THE FOREST RESEARCH LABORATORY
WORKS FOR OREGON
The Forest Research Laboratory at Oregon State
C
University has a long-standing tradition of research to support good forest stewardship. For 60 years, since it was
E
established by the Oregon State Legislature in 1941, the
FRL has pursued a wide-ranging research program directed at overcoming the challenges
that stand in the way of taking good care of Oregon’s forests.
R
In the 1940s and 1950s, as Oregon moved out of the dry Depression years, a big
challenge was the presence of vast acres of burned-over forest land. One of the FRL’s earli-
I
est projects was to provide research and technological support for the reforestation of the
Tillamook Burn. The success of that reforestation is evident in the vigorous young forest
now growing across the rugged Coast Range landscape.
D
The target of our research has broadened over the years. Forestry problems have grown
in complexity. The focus has shifted from the productivity of a single, big resource—the
timber—to an enhanced understanding of the relationships among the many resources of
Oregon’s forests.
The challenges are many. How shall we thin insect-damaged trees to reduce fuels in
E
dry east-side forests? How shall we grow forests in a way that helps them soak up excess
carbon dioxide from the atmosphere? How do we know how our management activities
will affect the forest decades into the future? How can we use our wood resource in the
H
most efficient, least wasteful way? How can we reach out to sometimes-warring constituents and help them reach agreement on tough forest-management questions?
As you will see from the profiles in this book, our researchers are pursuing answers to
T
these questions and more. Their work helps Oregon’s forest landowners, policymakers,
and citizens work toward sustainable stewardship of our forests now and in the future.
The research summaries in this report tell of some of the exciting things our scientists
are doing. I hope you’ll enjoy reading them, and I hope you’ll also take a look at the long
list of research publications. The depth and breadth of this published research is a testi-
M
mony to the rigor and relevance of FRL science.

solving problems and serving Oregon through sound forestry research remains the same.

THE FRL—
ENHANCING STEWARDSHIP
The word “stewardship” is commonly proposed as a model of the
human relationship with nature. The word is often invoked to mark out a
middle ground between the extremes of unchecked exploitation and unheeding preservation. It is a large middle ground, and people sometimes
have different ideas about where its boundaries lie. Still, researchers at
the OSU College of Forestry and the Forest Research Laboratory (FRL)
think stewardship is a principle worth upholding.
This report showcases the ongoing contributions to stewardship of
more than a dozen scientists at the College of Forestry and the FRL, the
College’s state-mandated research arm. Before we tell their stories, it
might be helpful to look back at what “stewardship” originally meant.
The dictionary traces the word to medieval times in England. “Steward” derives from the Old English words “stig,” meaning enclosure or
hall (our word “sty,” as in “pigsty,” comes from the same root), and
“weard,” meaning someone who guards or looks after.
The word originated during a time when most people in Europe lived
and toiled on large estates, under the protection and care (not always of
the highest quality) of the feudal lords who owned and managed these
estates. The chief steward of such an estate would be a trusted servant of
the lord, one who had the responsibility for the smooth running of the
entire estate.
Good stewardship required knowledge, first of all. The steward had
to know how to grow rye, how to breed sheep, how to store turnips, how
to keep the books. It also required a sense of responsibility. A steward was
responsible not only for the continued care of the land, not only for the
productivity of crops and livestock, but also for the well being of the
people whose livelihood depended on the estate’s continued prosperity.
Thus the principle of stewardship implies both knowledge and responsibility. It’s a principle that is even more important today. We no
longer live in medieval times. Our estate is the whole Earth, and that
makes our stewardship responsibility a heavy one indeed.
5
Scientists of the FRL contribute in many ways to the knowledge that
good stewardship demands. They also, in their work and in their lives,
exemplify a keenly felt responsibility for taking care of the Earth’s resources.
In this report you will read of the work of K. Norman Johnson, Pete
Bettinger, John Sessions, and Michael Wing, whose detailed and layered
mapping and modeling of Oregon’s forest lands makes it possible to take
care of the forest resource today and long into the future, for the well
being of our children and grandchildren.
You will learn how John Garland’s experiments with synthetic-fiber
rope and other harvesting innovations are taking care of workers by making the woods safer for those who harvest trees. You will read about the
efforts of Charles Brunner and Jim Funck to improve the utilization of
small logs, and Loren Kellogg’s work on efficient and environmentally
benign harvesting of these logs. You’ll learn about Darrell Ross’s work on
managing bark beetles with pheromones. All these researchers are helping owners take care of insect-damaged forests.
You’ll read about John Simonsen’s and Phil Humphrey’s work in engineering wood into brand-new materials— helping safeguard the forest
resource by enhancing the performance of wood and thereby stretching
the wood supply. You’ll read about Barbara Gartner’s investigations into
the cell-level processes of trees, which may lead to ways to cultivate wood
with better structural properties and thus help improve performance and
reduce waste.
You’ll see how Bruce Shindler and John Bliss are, through their socialscience research, helping policymakers take care of those who own and
work on the land, as well as those who are affected by how it is managed.
You will learn now Mark Harmon and Jim Wilson are, in a diversity of
research projects, helping citizens take care of the whole Earth by contributing to solutions for the problem of global warming. And you’ll meet
Jim Boyle, whose work on planted forests makes a strong case that these
forests are essential for global forest sustainability.

These scientists are all working toward the good stewardship of
Oregon’s forest resource today, but that is only the beginning. We believe
their ongoing work is crucial to the continued well being of our natural
resources and our human resources, here and around the world, now
and in the years to come.
PUTTING THE PIECES TOGETHER
“The strength of the CLAMS approach
is that it enables people to see that
the future they will experience will be
the consequence of choices they
make today.”
F
orests represent a complicated web
of links among biophysical processes
and human actions. Managers are increasingly trying to understand how their decisions will ripple across the landscape, and how
they will influence the forest over time.
Such understanding requires a detailed and
deep set of data about a particular landscape—a
richness of information that, before the advent K. Norman Johnson explains a
CLAMS map.
of satellite imaging and high-powered computers, was simply not available.
Five years ago, a partnership between Oregon State University, the USDA
Forest Service Pacific Northwest Research Station, and the Oregon Department of Forestry (ODF) was formed to launch CLAMS (Coastal Landscape
Analysis and Modeling Study), an ambitious project to compile information about Coast Range forests into a deep, layered, and finely resolved
database.
The CLAMS database is nearing completion. Researchers are running the
data through computer simulations to determine how various management strategies might play out in Coast Range watersheds over the next 100 years.
The computer-simulated outcomes are shown in detailed (and beautiful) maps of how the landscape will appear at various points in the future—
how much forest of differing ages there will be, and how its condition and
distribution will affect wildlife habitat, recreational opportunities, and the
economic well being of Coast Range communities.
The CLAMS database, says K. Norman Johnson, is a powerful tool for
showing policymakers and the public what the forests of the Coast Range
might look like at various points in the future if certain management choices
are set into motion today.

“These maps seem to draw people into the analysis,” says Johnson, professor in the Department of Forest Resources and a lead researcher with
CLAMS. “People can picture themselves in the landscape and envision what
the outcomes of various policies might be. That makes the maps a great tool
for joint learning.”
With its rugged topography, dynamic history of natural disturbance,
diverse ownership patterns, and disparate effects of past land management,
the Coast Range is about as varied as a landscape can be. “We’ve had some
practice at projecting the outcomes of various management strategies for
the whole landscape, but only in the aggregate,” says Johnson. “Now we
have the capability of simulating the spatial distribution of these activities
across the forested landscape, and we can project what our forests might
look like in the future in the different watersheds, mountains, and valleys
that make up the Coast Range.”
CLAMS’s co-leaders are Johnson and Tom Spies, a research ecologist
with the Pacific Northwest Research Station. Johnson and his Forest Resources colleagues Pete Bettinger, Becky Johnson, Jonathan Brooks, and Alissa
Moses, and Forest Science colleagues Rob Pabst and Steve Garman, are the
CLAMS team members from the College of Forestry. Forest Service partners include Gordon Reeves, Gordon Grant, Janet Ohmann, Kelly Burnett,
Mike McGrath, David Boughton, and Mike Wimberly. Gary Lettman, an
economist, and Andrew Herstrom, a GIS analyst, are team members from
the Oregon Department of Forestry.
Creating the database was a painstaking process. The Coast Range modeling area covers 7.7 million acres of ridges, slopes, hillsides, and valleys
stretching from Astoria to Port Orford and from the ocean to the Willamette
Valley margin.
The researchers began by dividing the landscape into parcels averaging
25 acres in size. The parcels are not identical squares in a grid, however.
They are delineated within each watershed according to the land’s contours,
and their irregularity of size and shape captures more closely the similarities
and differences of the land’s features.
Using GIS and satellite imagery, Janet Ohmann and Matt Gregory
(OSU) developed a vegetation map that Jonathan Brooks and Andrew
Herstrom used to develop the parcel layer. They overlaid the parcel map
and vegetation layer with boundaries representing ownership of Federal,
State, forest industry, and nonindustrial private forest lands.
Then the researchers made the resolution even finer. Pixels of 25 square
meters—the smallest unit of resolution possible with satellite images—were
grouped together according to shared characteristics, such as slope of the
ground, distance from a stream, and cover of vegetation.
These grouped patches range from a single pixel to several acres in size, but
their average size is about two-thirds of an acre. The patches are the “basic simulation units,” or BSUs, of the CLAMS computer-simulation process. It is the
changes in these BSUs that are tracked through the computer simulation.
The researchers also entered information about how Coast Range forest
lands had been managed in the past, and how owners and managers intend
to manage it now and in the future. This information was developed from
landowner surveys conducted by the Oregon Department of Forestry.
To simulate various potential futures, Johnson, Bettinger, and their colleagues feed into the computer information associated with a variety of
management scenarios. What are the management objectives of each owner
class? What does it cost to do a precommercial thinning? A commercial
thinning? A clearcut harvest? What price will the owner likely get for the
logs? Which lands have been harvested recently, and so are not expected to
be harvested again for a while? Which lands are withdrawn from harvest, or
restricted in some way?
Projecting changes in these attributes over time, the model produces a
detailed report and a set of maps of how the landscape will change decade
by decade. These maps show where the forests will lie on the ground, how
old the trees will be, and how much timber the land will yield. The maps
also facilitate an understanding of how wildlife habitat and recreational opportunities will be affected in different locations. The wildlife portion of
the model includes information on the western bluebird, pileated woodpecker, marbled murrelet, spotted owl, and elk.
One set of simulations shows what Coast Range forest cover looks like
today and should look like in 50 and 100 years, if forest owners continue to
manage their forests as they are managing today, or as they have indicated
they intend to manage in the future. This simulation assumes that federal
matrix lands (those available for harvest under the Northwest Forest Plan)
will continue to be harvested at a rate of no more than 1 percent per year in
each large watershed (5,000 to 50,000 acres) and that late-successional reserves will receive some selective thinning.
The simulation assumes that State lands will be managed with thinning
and clearcut harvests with the goal of achieving a full distribution of forest
structures within each large watershed. It also assumes that industrial landowners will continue to harvest by clearcut and thinning methods to achieve
an even flow of timber over time, with rotations averaging 50 years.

The maps show an increasing divergence between the forest condition
on public and private land, with the recent policies on public land focusing
on growing older, multi-structured forest, and those on private land focusing on growing and harvesting younger forest.
“The strength of the CLAMS approach,” says
Johnson “is that it enables people to see that the future

BUILDING A FOREST: LOOKING
TWO HUNDRED YEARS AHEAD
“Nobody assumes you’re seeing the
future perfectly, but you can use the
analysis to make a relative comparison among alternatives.”
A
tree planted today may take 100
years to grow to maturity. John
Sessions, a professor in the Department of Forest Engineering, says, “Foresters
routinely look 100 to 200 years into the future. Other businesses look 20 to 50 years ahead
at most.”
When the Oregon Department of Forestry
wanted to analyze the long-term effects of their John Seessions looks into the future.
draft management plan for the northwest Oregon State Forests—over 600,000 acres that includes the Tillamook and
Clatsop State Forests—the agency asked Sessions to help.
In the early to mid-twentieth century, much of northwest Oregon’s State
forest lands, then privately owned, had been burned by huge wildfires or
logged without replanting. Many acres of these lands had defaulted to Oregon counties for nonpayment of taxes. The counties agreed to let the Oregon Department of Forestry (ODF) reforest and manage the lands, and in
return, the counties would receive most of the revenues when the trees were
large enough to harvest.
Starting in the 1950s, ODF, replanted and reseeded these forests and
turned the burned or logged-over landscape into a growing forest. Today,
40- to 60-year-old, densely stocked stands of mostly Douglas-fir cover about
70 percent of northwestern Oregon State Forests. The remaining land is
covered by forest stands of other ages.
The Board of Forestry gave ODF the challenging task of developing a
new management plan for these State Forests. To meet policy direction,
ODF must manage the State Forests to provide habitat for threatened species such as the northern spotted owl, marbled murrelet, and several salmon
species, as well as more than 100 other wildlife species.To provide a full
11
12
range of social and economic benefits, the agency also must produce timber
from the forests and manage for recreation. Finally, the agency must manage the forests sustainably, so that the northwest Oregon State Forests will
provide wildlife habitat, clean water, recreation, and timber over the decades and centuries to come.
In partnership with the Oregon Department of Fish and Wildlife, ODF
developed an integrated management approach to meet all these goals. Their
approach is called structure-based management (SBM).
The old timber management approach looked at trees mainly as a future supply of lumber. This planning team looked at the way trees build a
forest. Trees give structure to a forest. The structure varies depending on the
sizes, ages, and species of trees, the number of snags and fallen trees, and the
types of shrubs and plants present. A healthy forest is a dynamic mosaic of
structures. These structures and their changing patterns make a forest what
it is.
The planning team’s goal was to grow half of the northwestern State
Forests into the two more-complex types of forest structures, known as “layered” and “older forest structure” types, as quickly as possible, in just a few
decades.
Would SBM work? The team turned to Sessions, who has developed
several computer models that analyze the short- and long-term consequences
of forest management actions.
Sessions developed a unique computer model designed specifically for
the northwest State Forests. For the analysis, planning team members divided these forests into 23,000 stands. The stands were further subdivided
into 131,000 smaller parcels, with separate parcels for riparian zones and
variations within the stands.
The next step was to use the computer model to simulate the management activities. For example, foresters could thin a 50-year-old stand of
trees, removing some trees and allowing the remaining ones to grow bigger.
Years later, the stands could be harvested for timber. After final harvest, the
area would be planted with new trees, and as these trees grew, thinning
decisions could be made again.
Working with College of Forestry graduate student Jeff Hamann and
ODF staff, Sessions entered 55 different thinning regimes, or pathways,
into the computer model, and 15 to 20 final harvest possibilities, varying by
the structure and age of the stand, the land allocation, and the type of harvest. The computer model then analyzed the possible decisions that could
be made to reach the SBM goals. For each of the 131,000 parcels, one of the
55 possible pathways was picked for the existing stand, along with the final
harvest age. After the final harvest, the stand could go down any one of the
55 pathways again. The model looked at the effects by decade for 200 years.
“On some stands you have potentially more than a million choices over
the next 200 years,” Sessions explains. Multiply the million choices by the
total number of stands, and the number of possibilities became almost astronomical just for one alternative. The team wanted to analyze seven alternatives.
Sessions began his work with the Oregon Department of Forestry in
November 1999. His computer model was able to analyze the seven alternatives and show the differences among them. “Nobody assumes you’re seeing
the future perfectly,” Sessions explains, “but you can use the analysis to
make a relative comparison among alternatives.” The team made their initial presentations to the Board of Forestry in March 2000, and the final
presentations in May 2000.
Sessions points out that the computer model does not replace on-theground fieldwork. Forest managers will still go out in the forest, collect data,
and make decisions. They will regularly monitor what actually happens on
the forest. The computer model gives some idea of the long-term consequences of a course of action. But even with all its data, the model is not
comprehensive. It is only a simulation. Unpredictable changes occur, such as
fires, windstorms, and most unpredictable of all, changing human values.
The Board of Forestry began the process to adopt the Northwest Oregon State Forests Management Plan as an administrative rule on September 6, 2000. After public review, the plan was approved in January 2001,
and SBM became the new management direction for Oregon’s northwest
State Forests.
Sessions’s computer analysis helped the planning team understand the
cumulative effects of their plan. The team looked 200 years ahead and was
able to say with more confidence that structure-based management would
produce a healthy, sustainable forest.
“Stewardship is strongly associated with sustainability,” Sessions says.
“It means sustainability of forest structures and forest conditions, and also
the types of ouputs that society values—sustainability of local communities
and employment. Then we’ve added sustainability of forest structure for
wildlife and water also.”
Although he refers to his computer model as a “harvest scheduling
model,” Sessions points out that the model is more than that. “The model
addresses not only what goes, but what stays.”

forest managers see a need to thin
these stands. But the pole-sized trees are usually less than 10 inches in diameter. Traditionally such trees have had little value to mills.
“The people who own the forest want to do stand management economically, but they can’t right now because the mills won’t bid on smalldiameter timber, or they bid very low,” says Jim Funck. He and Charles
Brunner, associate professors in the Department of Forest Products, are working on a project to find the most value in the harvest and use of smalldiameter timber.
Brunner’s and Funck’s study is one part of the Fund for Rural America
Small-Diameter Timber Project, funded by the U.S. Department of Agriculture. The overall project has three key objectives: to promote good forest
stewardship, to provide jobs to rural communities, and to make small-diameter timber more economically viable.
Brunner and Funck are working with their Forest Products colleague
John Punches, the Forestry Extension agent in Douglas County. Other participants are researchers in various divisions of the USDA Forest Service;
specifically, the Pacific Northwest Research Station, the Rogue River National Forest, the Forest Products Laboratory in Madison, Wisconsin, and
the State and Private Forestry program.
Typically, when a mill bids on a timber sale, says Funck, it assigns values
to logs based on their potential value as boards. Smaller logs can be more
valuable as cut stock (that is, window frames, doors, moldings, and other
manufactured products), and indeed the mill might eventually capture higher
profits by selling some boards to a cut-stock manufacturer. However, there
is no guarantee that such a market will be available, and thus no reason for
the mill to pay a higher price for small logs at the outset.
Brunner and Funck are working on a method to determine the best
utilization, and hence the highest value, of small-diameter logs. Ultimately
their work could help sawmills maximize the value of timber sales in smalldiameter stands. If small logs are more valuable, it may become more profitable to thin fire-prone forests to reduce fuels.
The researchers’ first need was to gather information about the quality
of lumber that comes from small-diameter logs. Brunner and Funck developed a method for tracking a small log through the felling, bucking, and
sawing processes and measuring the defects and other characteristics of the
resulting boards. Then, using a computer model, they devised a process for
virtually reassembling the boards back into the configurations of the original logs.
The trees being studied are Douglas-fir and ponderosa pine logs between 5 and 10 inches in diameter, thinned from stands on the Rogue River
National Forest. The researchers took detailed measurements of each felled
tree, including knot and branch patterns, stem size, and stem taper. The
trees were then bucked into 16-foot logs and sawn into flitches—unedged
boards. The flitches were “mapped” according to where they had come from
within each log.
The flitches were hauled to the
laboratory at the College of Forestry. Brunner and Funck used a
track-mounted camera to take pictures of each flitch. The photographic images recorded the shape
of the flitch and size and placement Scan of a log, virtually reassembled by the computer,

nificant feature.
The images were scanned into a computer database, and then reassembled
by the computer into an image of the original log. These computer log
forms can be “sawn”—virtually speaking—over and over again in different
ways. The computer model enables Brunner and Funck to explore all the
15
possibilities for the best utilization of a particular log in light of the current
value of different types of products.
For larger trees, the optimal yield is usually from plain lumber. But for
these small-diameter logs, says Funck, the knots and other defects and the
variations in the taper of the log results in lumber of widely varying grades.
“We needed to look at the next step beyond lumber, at making cut-stock
parts, to see if the tree could be worth more than its value as lumber,” Funck
says.
Subsequent economic analyses found that, for most configurations tested
through the computer model, the wood was worth more as moldings, trims,
and other specialty wood products than it was as plain lumber.
If these higher values could be routinely captured, small-diameter trees
could be worth much more to bidders on timber sales. However, say Brunner
and Funck, few mills are now set up to take advantage of these higher values. Sawmills and cut-stock mills will need to cooperate, perhaps forming
partnerships, in order to realize the maximum value from these small logs.
He and Funck will be bringing their research to the attention of mill
managers and buyers through an outreach effort, soon to be undertaken in
cooperation with OSU Forestry Extension and the Forest Service’s State
and Private Forestry Program.
The good news, say Brunner and Funck, is that good forest stewardship
has at least the potential for being economically viable. It’s hard for forest
managers to get needed thinning done when there’s no money in it, says
Funck. “But more-profitable thinning may at least reduce the subsidy that
has to be paid to get someone to do stand management for stewardship
purposes.”

ACTIVELY RESTORING EAST-SIDE FORESTS
The expertise and technology
exists to harvest trees from
these distressed forests in an
environmentally sensitive way.
L
ast summer’s devastating fires
throughout the western United
States served as a reminder that
the dry conifer forests of eastern Oregon
and much of the inland West are still vulnerable to catastrophic fire.
Managers now have choices beyond
simply letting nature take its course.
Loren Kellogg’s work shows ways to reduce
Loren Kellogg’s studies in small-log harfuels profitably in stressed east-side forests.
vesting on Forest Service lands in Oregon’s
Blue Mountains are showing that it is possible to reduce the risk of fire in
these forests—and generate a profit at the same time—while benefiting the
environment.
The problems in east-side forests have been nearly a century in the making. Historical logging of the dominant ponderosa pine, coupled with a
policy of suppressing the frequent, small wildfires that periodically swept
through pine stands, has changed the composition of these forests markedly
from what it was before European-American settlement.
Once-open understories are now crowded with Douglas-fir, grand fir,
western larch, and lodgepole pine, species vulnerable to attack by the mountain pine beetle and the western spruce budworm. The dry spell of the mid1980s through the mid-’90s stressed the trees and exacerbated the insect
attacks, resulting in high concentrations of dry fuels on the ground, as well
as standing dead trees.
Kellogg and several OSU scientists coauthored a 1995 report to Governor John Kitzhaber on the state of forests in eastern Oregon’s Blue Mountains. Most of the forest is alive, wrote the authors, but much of it is severely
stressed. Kellogg and the other scientists suggested that active management
could move these stands closer to the historical mosaic of forest conditions
that existed immediately before white settlement.
17
18
Kellogg has been working for several years on ways to actively manage
stands and reduce fuels in these forests. He and his doctoral student, Peter
Matzka, recently completed an experiment in thinning and prescribed burning on several fire-prone stands in the Wallowa-Whitman National Forest
near Enterprise, Oregon. The study, called Hungry Bob, was located in the
Wapiti Ecosystem Management Project Area. It compared three different
management scenarios for east-side forests: thinning alone, prescribed fire
alone, and thinning combined with prescribed fire.
Kellogg and Matzka wanted to know not only the yield and profitability of the harvested timber, but also the costs of prescribed fire and how
different stand conditions affect the economics of forest operations. Other
scientists in this multidisciplinary study are investigating how each treatment will affect the production of morels, an edible fungus that can be a
valuable secondary forest product. Also being studied is the degree of damage to the residual stand from thinning and prescribed burning.
An important objective of Kellogg’s and Matzka’s research is to develop
a decision matrix that will help forest managers evaluate different stand conditions and other variables and decide what to do in particular situations.
“There are so many variables,” Kellogg says. “Stand structure and composition are different in each stand. The amount of fuel loading varies, and the
type of fuel varies. The economic feasibility varies depending on log prices,
transportation costs, and the expense of the equipment. Potential environmental effects vary depending on the terrain and proximity of streams, as
well as the impacts of the different harvesting equipment on the site. The
risk of introducing prescribed fire certainly varies from site to site.”
The decision matrix, a major component of Matzka’s dissertation, will
be something like a flow chart that lets managers step through these variables one at a time, identifying economic and environmental tradeoffs that
occur among different stand management treatments and forest operations
techniques.
The thinning at Hungry Bob was carried out in 1998 with a cut-to-length
system that employed a harvester and a forwarder. A harvester is a sophisticated
machine that fells the tree, shears off the branches, and bucks the bole into
desired log lengths. The forwarder loads the logs and transports them to the
roadside. The severed branches and their twigs and needles are left on the ground
to provide cushioning to the soil against the weight of the machine. The sites
receiving prescribed burning were burned the following fall.
Economics of the operation were carefully projected, says Kellogg. Because
the machines are expensive to purchase and operate, and the timber value pro-
vided by these distressed stands is usually low, the harvesting must be planned
carefully. “We were working in stands where you have maybe 10 to 30 percent
high-value sawlogs, and the rest is low-value pulpwood,” he says.
The Hungry Bob study is a fully replicated scientific experiment building on information gleaned from two earlier studies Kellogg conducted in
the Blue Mountains. The Hungry Bob results are not yet complete, but
these earlier studies provide reason for optimism. Kellogg and his students
investigated various combinations of small-log harvesting equipment to
determine the economic and environmental effectiveness of each alternative, and found that harvesting could achieve both stewardship and profit.
The first study, called Deerhorn, took place in 1994 on a site about 50
miles southwest of Pendleton. Trees were felled, limbed, and bucked by a
harvester and yarded by a small skyline yarding system. Objectives of the
harvest were to reduce fuels, improve conditions for the remaining trees,
and minimize damage to the soil and the trees. Kellogg and his master’s
student, Cameron Brown, found that the harvester-yarder combination succeeded in all these objectives, and made a profit besides. Although only 29
percent of the yield was in sawlogs, a good log price at that time ($515 per
thousand board feet) allowed that segment of the operation to more than
cover losses from harvesting and utilizing the pulpwood.
In the second study, called Limber Jim, Kellogg and his master’s student, James Doyal, worked with researchers from the University of California at Davis to compare a harvester-skyline yarder combination, the system
used at Deerhorn, with a cut-to-length system.
Conditions in that forest were different from those at Deerhorn. Only
12 percent of the yield was sawlogs for the skyline system, only 6 percent for
the forwarder. In addition, log prices were lower, $425 per thousand board
feet. Both harvesting systems produced similar and acceptable results in
terms of fuels reduction and low soil disturbance, but at different stump-tomill costs: $42 per green ton for the harvester-forwarder system, versus $72
per green ton for the harvester-skyline system.
The good news from these studies, says Kellogg, is that the expertise and
technology exists to harvest trees from these distressed forests in an environmentally sensitive way, reducing fuels and lessening the risk of catastrophic fire.
And if such management can also turn a profit, there’ll be less need for
government subsidies. “For people to buy timber sales and invest in these
half-million-dollar machines,” says Kellogg, “these operations have to be
profitable. And they can be. With the right system and careful planning, it
can be done.”

SPEAKING THE DOUGLAS-FIR
BEETLE’S LANGUAGE
Pheromones are not pesticides—they
do not actually kill any insects, and
they do not have any of the health or
environmental concerns associated
with many pesticides.
D
20
ouglas-fir beetles “speak” to each
other in the language of pheromones—chemical signals that send
messages to other Douglas-fir beetles. Research
done at Oregon State University in the 1970s
contributed to the identification of these chemicals and the messages they transmit.
Darrell Ross, associate professor in the DeDarrell Ross with a bag full of
Douglas-fir beetles.
partment of Forest Science, is taking this research to the next stage. He is investigating how
to use these signals to manage the beetles and their impacts on forests. “I’m
learning to speak the Douglas-fir beetle’s language,” says Ross.
Ross is devising techniques for, among other things, using pheromonebaited traps to attract and kill Douglas-fir beetles. Pheromones are not pesticides—they do not actually kill any insects, and they do not have any of
the health or environmental concerns associated with many pesticides. The
traps catch the beetles and kill them with a small amount of pesticide used
in the trap’s collection cup. No spraying is involved.
Pheromone techniques are beginning to be used operationally as part of
an integrated program of forest stewardship—as an additional tool in the
manager’s toolbox, along with silvicultural tools such as thinning and salvage logging.
Douglas-fir beetles feed on and breed in the phloem of recently dead
Douglas-fir. The phloem is the tissue between the bark and wood. Since
dead and dying trees are normally scarce in the forest, the Douglas-fir beetle
has evolved an aggregation pheromone—a chemical signal that tells other
Douglas-fir beetles in the area, “here’s a dead tree.” The signal attracts large
numbers of beetles to the tree.
When the tree cannot support any more Douglas-fir beetles, the beetles
send out another chemical signal, an antiaggregation pheromone called 3methylcyclohex-2-en-1-one (MCH). “The antiaggregation pheromone serves
as a ‘No Vacancy’ sign,” Ross says. “It tells the other beetles the tree is full,
and keeps them from overpopulating the resource.”
The beetles are normally present in low numbers in the forest. But when
a windstorm or forest fire kills a large number of Douglas-fir trees, a beetle
outbreak can occur. The beetles move into the dead trees and lay eggs, then
their broods overwinter. When a new generation of beetles emerges the next
spring, the beetles seek out live trees, if there are not enough dead ones.
Because the Douglas-fir beetles can survive only in dead trees or dead parts
of trees, they need to kill the live trees. It takes many beetles to kill a large
Douglas-fir, their preferred target. The first beetles to colonize a live Douglas-fir send out the aggregation pheromone, a signal that calls other beetles
to the tree. The beetles make a mass attack on the live tree and overwhelm
the tree’s self-defense.
In the past, foresters responded to Douglas-fir beetle outbreaks by salvage-logging the dead trees and the live trees attacked by the beetles. But
two things changed, Ross explains. First, particularly on national forest lands,
foresters now manage with goals of forest stewardship and ecosystem management, rather than primarily for timber.
Second, not many large, old Douglas-firs remain in the mixed-species
forests of eastern Oregon, Washington, Idaho, and Montana. Forest managers in eastern Oregon usually want to retain all the large, old Douglas-fir
they have. Using techniques developed by Ross and his cooperators, these
managers can use pheromones to protect some trees from beetles, to trap
and kill beetles, and to attract remaining beetles to areas where some tree
mortality is acceptable. In these areas, beetle-killed trees can either be harvested or left for snags.
In their studies on the Wallowa-Whitman National Forest and other
locations, Ross and Gary Daterman, of the USDA Forest Service Pacific
Northwest Research Station, are conducting many trials to refine their techniques—to speak the beetles’ language more effectively. They are learning
the best ways to apply the pheromones, what doses are most effective, and
which trap designs and locations work best.
In one strategy, the antiaggregation pheromone, MCH, packaged in
plastic capsules, is placed in trees and then removed at the end of the season.
Ross has found that MCH keeps Douglas-fir beetles away from trees that
would otherwise be attacked.
21
The antiaggregation pheromone was registered by the Environmental
Protection Agency in 1999 and is now available to foresters for operational
use. Just in the past year, forest managers have used MCH and Ross’s techniques in eastern Oregon, Washington, Idaho, and Montana. Applied once
in the spring, MCH is effective all year. A Douglas-fir beetle outbreak typically lasts two to three years, so MCH will have to be applied for several
years in a row.
The research has reached the point where pheromones such as MCH
can now be used on a landscape level. “It won’t be used on thousands of
acres,” Ross says, “but rather in specific areas over a large landscape. Managers might treat old-growth Douglas-fir in recreational areas or other highvalue areas. Other areas could tolerate some tree mortality or might benefit
from additional snags, or salvage logging could be done. Then managers
could draw the beetles to those areas.”
The large forest fires of the summer of 2000 left thousands of acres of
dead and fire-damaged trees. The scorched trees and live trees near burned
areas will be highly susceptible to Douglas-fir beetle outbreaks over the next
few years. Ross expects a lot of interest from forest managers in using pheromone techniques to protect mature trees.
“We can use MCH to change the beetles’ behavior,” Ross says. “We can
protect the large, mature trees, of which we have a shortage, until other trees
grow to those ages and sizes.” By speaking the Douglas-fir beetle’s language,
Darrell Ross is helping forest managers achieve their objectives in a way that
works with natural processes.

TAKING CARE OF THE PEOPLE WHO TAKE CARE OF
THE FOREST
Sometimes the discussions
about better forestry do not
mention the people who actually do the work—as if stewardship could somehow be accomplished without them.
M
odern forestry emphasizes
stewardship of forest resources. Harvesting operations are designed to protect wildlife,
water quality, and fish. But sometimes the John Garland (right) acquaints a
colleague with synthetic rope.
discussions about better forestry do not
mention the people who actually do the work—as if stewardship could somehow be accomplished without them.
“Who takes care of the forest?” John Garland (Forest Engineering) asks.
“We have an idea that it’s foresters, because they’re the ones who make decisions and make plans on computers. But the people out in the woods doing
the work are essential to the success of the project. The loggers are the applied ecologists.”
Throughout his career, Garland has focused on stewardship of the human resource in the forest. He has worked to improve safety and working
conditions in the forest. He has also designed and taught training programs
that teach loggers about forest ecology and silviculture, safety, changing forest regulations, Best Management Practices, and sustainable forestry.
“If we want to practice sustainable forestry,” says Garland, “we need to
train the people who actually do the work on the ground.” His training
programs respect and incorporate the extensive knowledge that loggers already have about the forest.
Currently Garland is working with the Oregon Occupational Safety and
Health Administration (OR-OSHA) to make ergonomic improvements in the
logger’s workplace. Ergonomics is the applied science of designing a workplace
that maximizes productivity by minimizing worker fatigue and discomfort.
23
24
Although working in the forest has many inherent risks that cannot be
eliminated, much can be done with the equipment and practices that loggers use, in order to reduce fatigue, improve safety, and improve productivity. “If we can lighten the workload,” Garland says, “then we have good
prospects for reducing fatigue and injuries.”
Garland is researching a synthetic rope, a new product that helps loggers do their job better. The synthetic rope is much lighter than traditional
steel rope but equally strong. That in itself is an improvement, but the synthetic rope has other benefits as well. It offers greater flexibility in where
lines are placed in logging operations, and thus presents new options for
tree harvesting and logging systems.
Garland first learned about synthetic rope from a logger, and was intrigued by its possibilities and how it might change the logging workplace.
Garland received a grant from OR-OSHA to study synthetic rope and its
potential applications in logging operations. Under this grant, Garland is
working with a twelve-strand braided rope made of ultrahigh molecular
weight polyethylene. It resists ultraviolet light and abrasion, and it floats.
Wire rope has a tendency to develop, needle-like splinters, and workers
have to take precautions to avoid injuries from these “jaggers.” Synthetic
rope does not have this problem. However, being more flexible than traditional wire rope, synthetic rope is more likely to get accidental knots. Moreover, there are still questions about synthetic rope’s stretch and durability,
and synthetic rope may not replace steel rope in all situations.
Although it is not against the safety codes to use the synthetic rope right
now, Garland cautions that a degree of restraint should be used. Much is
still unknown about the synthetic rope’s capabilities, and it could be dangerous if used inappropriately. The synthetic rope is being used for static
guylines, straps, and intermediate support lines. Garland is investigating its
use for chokers, winch lines, running lines, and skylines.
Garland is also working on several improvements and refinements. For
example, it is difficult to connect synthetic rope to traditional wire rope.
Garland is seeking another grant to develop end connectors that make it
possible to connect the two types of rope. A satisfactory design will open
opportunities for companies to manufacture the connectors.
Another possible development is the placement of a fiber optic strand
down the center of the synthetic rope when it is manufactured. It is currently impossible to detect damage in the center of ropes, yet this unseen
damage can lead to rope failure. A fiber optic strand transmits light no matter how many bends or coils a rope has. Thus, a person could shine an
ordinary flashlight into the fiber optic strand at one end of the rope, and if
the strand were intact, light would come out of the rope’s other end. The
fiber optic strand would be an additional safety feature, allowing a simple
test for unseen damage.
Although the synthetic rope costs about four times as much as wire
rope, it weighs only about one-sixth as much. In Garland’s test operation, a
steel rope guyline weighed 111 pounds. A guyline of synthetic rope weighed
18 pounds and was able to carry the same payloads. If the synthetic rope
leads to a gain in productivity,
Garland says, it could easily pay
for itself.
The synthetic rope has been
tested by Oregon State University’s
student logging crew. It reduced
the physical demand of logging,
as measured by the heart rates of
student workers. Women crew
members carried the synthetic
rope up a 40 percent slope, and
found it much easier than carry- These instruments are used to monitor heart rates
of crew members.
ing wire rope.
“The forest industry in Oregon is alive and well, and it’s changing rapidly,” Garland says. “Timber is
being harvested with a high-tech approach. Harvests now are likely to selectively remove trees and logs. Synthetic rope is helpful with these more selective operations.”
Oregon State University has long been known as a leader in the development of logging technology and innovative forest products. Garland’s
research continues this work. In addition to his studies of new products,
Garland is working on improving workplace safety. He is the university
representative on a committee working with OR-OSHA, helping the agency
to revise Oregon’s Forest Activities Safety Code.

MAPPING THE MANY LAYERS OF SALMON HABITAT
“If we can find a way to make
these workshops portable and
present them to the watershed
councils in their own districts,
we can help empower the
councils to conduct watershed
assessments.”
I
26
n the 1990s, the decline of salmon
emerged as a major environmental
problem in Oregon. But little was
known about the current condition of
Michael Wing, knee-deep in the South
freshwater salmon habitat in the streams
Santiam.
where salmon spawned.
Work done by Michael Wing, of the Department of Forest Engineering,
will help people better measure stream conditions, and thus better target restoration work. Government agencies, watershed councils, and volunteer groups
will all be able to use Wing’s analysis and his techniques to get a better understanding of habitat quality and restoration needs for individual streams.
The Oregon Department of Fish and Wildlife (ODFW) developed the
Aquatic Inventory Project in 1990 to collect better information on freshwater habitat in Oregon streams. The agency also developed a detailed protocol and training sessions to create a standard survey approach for measuring
aquatic habitat conditions. Through the project, stream survey data were
collected consistently by crews from several agencies and organizations,
making it possible for ODFW to gather data from many more streams than
their own crews could cover alone.
Since 1990 this protocol has been used to collect information on thousands of streams across Federal, State, private, and tribal land ownerships,
creating a huge database. The great volume of data has made analysis very
challenging, however. Given current concerns about salmon habitat, the
FRL Advisory Committee has made the analysis of the database a research
priority.
Michael Wing was hired by OSU’s Department of Forest Engineering
to tackle the challenge of analyzing the database. In collaboration with For-
est Engineering professor Arne Skaugset and an advisory group composed
of College of Forestry and agency representatives, the decision was made to
transform the stream survey database into a geographic information system
(GIS) environment. GIS is a computer system that stores and analyzes spatial data.
Spatial data are better known as information that can be displayed on a
map. Once spatial data are digitized, or entered into the computer, GIS can
be used to organize the data in layers, or themes. The system can add new
layers of data, merge data layers, and analyze the data in ways not possible
with conventional maps.
“GIS is a great tool,” says Wing. “We would have been very hard-pressed
to move ahead with analyzing this database without GIS. It opens up the
database and allows us to make it stronger.”
Most GIS projects cover only one watershed or a district. It took Wing
and his assistants nine months to create a GIS database with the survey data
from hard-copy maps of 1,370 streams in western Oregon, an area from
Astoria to Ashland and from the Coast to the Cascades.
In their fieldwork, the survey crews divided the streams into 3,793
reaches, using criteria such as stream junctions and changes in forest cover.
The crews collected data on roughly 80 variables important to salmon habitat, including the amount of large wood in and near a stream, the number
of pools and their depth, and the type of stream substrate, and the material
that forms the streambed.
At that point, Wing had stream habitat maps for much of western Oregon. Those maps were valuable, but GIS could do even more. “The real
advantage was that GIS allowed us to add information that was not included in the survey data,” Wing explains.
GIS allows a researcher to overlay data sources, a computerized and
more-sophisticated version of transparency overlays for maps. Wing obtained
GIS maps that showed geology and land ownership from the Oregon State
Service Center for GIS (SSCGIS) in Salem. On the computer, he draped
those layers on top of his stream habitat map. Maps could then be printed
with one, some, or all of the layers for any surveyed stream or watershed.
Wing also used a program that added stream-order information into
the GIS database. The uppermost streams in a watershed can be classified as
first-order streams; at the first junction with another stream, a second-order
stream is formed, and so on down the watershed. It would have been extremely time-consuming to classify stream order from topographical maps,
but the new program classified the streams in a matter of hours.
27
With the new data, Wing was able to find relationships not revealed by
the original database. He found that, for streams on forest land, stream
order was the most important variable related to the amount of large wood
in the streams. First- and second-order streams in the upper watersheds had
much more large wood than did higher-order streams farther down in the
watershed. Land ownership was not a significant factor influencing the
amount of large wood in the streams.
Wing found that when comparisons were made among different types of
ownerships—for example, between Federal and private forest lands—there
were only small differences in the amount of large wood or the number of
pools in the streams. The significant differences emerged between streams
on forest land and streams in different land uses, such as agricultural or
urban areas.
“Our forested streams are in relatively good condition, including streams
on forest industry lands,” Wing says. He suggests that restoration work might
be focused on streams lower in the watersheds, which generally have less
large wood and fewer pools, and yet are often the streams most accessible to
salmon.
Currently Wing is working on a finer scale of analysis. Within the stream
reaches, survey crews identified habitat units, which are identified by the
pools, riffles, or rapids that define the streams, and are usually no longer
than the stream is wide. The database contains 350,000 habitat units. A
single analysis at this level of resolution may take days for the computer to
complete.
Forest managers and watershed councils can use the results of these analyses to guide their actions and improve their stewardship of streams. Wing is
teaching people how to use GIS through continuing education workshops
at OSU. Once a person has completed one of Wing’s workshops, he or she
has the skills to access the ODFW database on the Internet and query on
specific information for a stream or watershed.
Wing is working on a proposal that will make the GIS workshops more
accessible to Oregon’s watershed councils. Many of these groups have limited resources for training members, who are mostly volunteers. “If we can
find a way to make these workshops portable and present them to the watershed councils in their own districts,” Wing says, “we can help empower
the councils to conduct watershed assessments. GIS has emerged as one of
the most significant and widely used tools available for forestry and natural
resources research.”

PUTTING NUMBERS ON WOOD’S ENVIRONMENTAL
PERFORMANCE
“Consumers, through their
architects and builders, will be
able to choose the best ways to
reduce energy use or CO2
emissions.”

though it is sustainable, renewable, recyclable, and manufactured with relatively little in the way of toxic ingredi- Jim Wilson is documenting the

ents or emissions.
Now Wilson is taking part in a comprehensive, nationwide study that
will provide valuable information to consumers and policymakers on the
environmental performance of wood. It will help them consider all the factors that affect whether a given building technology—wood, concrete, steel,
or plastic—is environmentally friendly or not.
“We believe strongly in the environmental friendliness of wood,” says
Wilson, professor in the Department of Forest Products. “What we’re doing
now is documenting it.”
Wood, he says, has another advantage over concrete and steel, its two
main competitors as structural building materials. A growing forest is a carbon sink that scrubs the air of excess carbon dioxide (CO2) emissions. Planted
forests have been proposed by some policymakers as a means for removing
excessive amounts of CO2, a so-called greenhouse gas, from the atmosphere.
What’s more, structural wood products tie up carbon as long as they remain
intact. Wood releases carbon, in the form of CO2, back to the atmosphere
only when it decomposes or is burned.
Wilson is working with a team of scientists from 15 universities and the
Forest Service to assess the environmental performance of wood building
materials, “from cradle to grave.” In a process known as life-cycle analysis,
the team is looking at all the material and energy inputs and outputs, from
29
30
the planting of the seedling, to the growing of the tree, through harvesting,
transportation, manufacturing, home construction, home use and maintenance, and eventual disposal or recycling of the wood.
Consider all the inputs—material and energy—required to build and
occupy a 2,000-square-foot new home throughout its service life. How much
electricity, gas, other fuels, and water are consumed in the course of growing
and harvesting the trees for the wood products used to build the house?
How much energy is used to manufacture the lumber, plywood, beams, and
trusses? How much adhesive is used to hold the plywood and laminated
beams together? How much material and energy is needed for heating and
maintenance?
Then consider the outputs. How much carbon monoxide is emitted by the
truck that carried the logs to the mill? How much formaldehyde and volatile
organic compounds go into the air and water in the manufacturing process?
How much carbon is sequestered in the lumber? How much carbon is absorbed
by the trees planted to replace those logged? How much CO2 and methane gas
will be released into the atmosphere if the lumber is allowed to decay, or is
burned, after the house is torn down? How much less CO2 will be released if the
lumber is recycled rather than dumped in a landfill?
Finally, what is the combined effect on the environment of all these
inputs and outputs multiplied by the 1.4 million new houses built in the
United States each year?
These are some of the questions that the six-year, $5-million study will
address. The answers, says Wilson, will help counter the false perception
that harvesting trees to make wood products harms the environment. The
study will also help the wood-products industry address real environmental
concerns through cost-effective management practices and process improvements.
“What would the environmental impact and cost be of, say, changing
from wood-fired boilers to gas-fired,” says Wilson, “or adding more pollution control devices to the wood dryer or hot presses? Pollution control
devices typically use a lot of energy—electricity and natural gas, both of
which are rapidly increasing in price and are becoming limited in availability. What are the best alternatives and tradeoffs? When the study is completed, manufacturers will be able to answer those questions more accurately.” This capability will help the industry maintain its competitive edge
over steel, concrete, and plastic for building materials.
Wilson’s study is funded by the Forest Service and the participating
universities, with additional funding from wood-products manufacturers
and manufacturing associations. It expands on a 1976 project undertaken
by the Committee on Renewable Resources for Industrial Materials
(CORRIM), sponsored by the National Academy of Sciences at the request
of President Jimmy Carter during the last U.S. energy crisis.
That study considered only the energy and material inputs of wood
products used in homes, and only from manufacturing through construction. By adding emissions and carbon balance to the scope of research, and
by looking at the entire life cycle of wood products from planting trees to
eventual disposal or recycling, “our study has greatly expanded those boundaries,” says Wilson.
Wilson is on the steering committee for the whole project. He oversees
the technical subcommittees dealing with the forest resource, manufacturing, wood structures, and the use and disposal or recycling of wood products.
The current study, CORRIM II, is now in its first phase, a two-year,
$1.2-million effort to gather the quantities of data that will be required and
to refine the analysis and modeling procedures. The team is working on
interfacing the analysis methods with those used in similar studies in Canada
and Europe, to provide a basis for comparing wood’s environmental performance internationally.
The scientists will calculate all the energy and emissions per unit of
material, then multiply those numbers by the amount of material used.
They will figure inputs and outputs for each step in the manufacturing
process. How much of every kind of energy and emissions is associated with
peeling a log for veneer? For generating the steam to soften the wood? For
drying the veneer? For hot-pressing it together into a piece of plywood?
How much for various fuel sources? How much for emission control devices?
When it is finished, says Wilson, the CORRIM II study will provide a
powerful tool for answering all kinds of questions about the environmental
performance of wood. Application of the study’s results will help manufacturers efficiently improve their environmental performance and provide
comparative numbers to consumers about the environmental benefits and
costs of building with wood, steel, concrete, or plastic.
“Consumers, through their architects and builders, will be able to choose
the best ways to reduce energy use or CO2 emissions, if these are priorities,”
says Wilson. “And our elected leaders will have access to good data as they
make decisions about natural resources that affect all our lives.”

FORESTS AS CO2 SPONGES
“If we allowed forests to
grow longer between harvests, and if we left more
live and dead trees out
there to drive up the average storage on a site, I think
it might be possible to
double the store of carbon

is it? Early in his scientific career, Mark Harmon was answering that question on a very small
scale, measuring carbon in bags of leaves and pieces of wood. His master’s
program advisor, ecologist Jerry Olson at the University of Tennessee, was
looking for carbon on a broader scale—across watersheds and landscapes
around the globe—with the help of increasing quantities of gathered data
and early mathematical and computer models Harmon and others were
developing.
Tracking down carbon may seem an esoteric pursuit, but it can help
policymakers address an urgent, worldwide issue. Carbon, in the form of
carbon dioxide, or CO2, released into the atmosphere by the burning of
fossil fuels, is a chief factor in the gradual warming of the Earth’s atmosphere that many scientists think is triggering a global climate change.
Both living plants and decomposing dead ones play a crucial role in the
balance of the world’s atmospheric carbon dioxide. All living plants absorb
CO2 from the air—it is a building block of all organic matter. Young, fastgrowing plants, rapidly adding biomass, absorb it faster than older plants.
Policymakers concerned with global warming are looking to forests to help
absorb excess CO2 from the atmosphere.
Harmon, who holds the Richardson Chair in the Department of
Forest Science, began his career at OSU studying rotting logs on the
H.J. Andrews Experimental Forest, on the west slope of the Oregon
Cascades. When he joined the faculty in 1984, Harmon initiated a 200-
year study of carbon release and many other processes associated with
decomposition of wood.
These days, following in his advisor’s footsteps, Harmon has broadened
his search for carbon to a worldwide scale, looking for CO2 uptake and
release patterns in the temperate forests of North America and the boreal
forests of northern Russia. Thanks to powerful computer models, remote
sensing, and other high-tech investigative tools, he says, it is becoming possible to know at least approximately how much carbon there is in a forest, a
watershed, a region, a continent, even the whole world. He is in the midst
of several carbon-related studies, collaborating with Forest Science colleague
Warren Cohen, a remote-sensing expert; OSU economist Joe Kerkvliet; and
others.
In one study, Harmon and Forest Science colleague Olga Krankina are
working with seven Russian forestry scientists to refine measurements of
dead wood in Russia’s vast taiga, the conifer-forested region that occupies
nearly half Russia’s land area and stretches from the Baltic to the Pacific.
Almost one-fifth of the world’s forests lie in that boreal belt.
In the past decade, scientists have become aware that, around the world,
carbon is being taken up faster than it’s being given off—good news for
global warming. But nobody knows why there’s a “carbon sink,” or exactly
where it might be.
“We haven’t been able to balance the books globally,” says Harmon.
“Because the Russian forests are so extensive, we felt it was important to
know what they’re actually doing in the carbon budget.”
From taking surveys of salvageable dead trees, the Russian forest service
already had rough estimates of the amount of dead wood in its forests. But
these surveys weren’t accurate on certain measures critical to the carbon
equation, such as the volume of trees too rotten to salvage. Harmon and
Krankina are helping the Russian scientists devise more-precise ways of
measuring the dead wood.
Some scientists, Harmon says, think the missing carbon sink is in North
America, where formerly deforested lands, especially in the East and Midwest, are growing trees again. “There’s a political dimension to this question,” he says. “We in North America are the biggest users of fossil fuels—
which put carbon into the air—while we have only 5 percent of the world’s
forests.” Knowing the role of Russian forests will give policymakers more
information as they tackle the question of how to assign responsibility for
abating global warming.
33
34
The idea of using forests to help scrub the air of CO2 has added more
controversy to an already controversial issue. “How a forest is managed,”
says Harmon, “can make a big difference in how much carbon it stores, or
releases.”
One suggestion, plausible on the surface, is to harvest older forests, which
aren’t doing very much in the way of CO2 uptake, and replace them with
young plantations. That proposal, unsurprisingly, was not popular with conservation groups. In a controversial 1990 paper published in the journal
Science, Harmon and colleagues Jerry Franklin (University of Washington)
and Bill Ferrell (OSU Forest Science) noted things weren’t quite that simple.
“The complicating factor is scale,” says Harmon. “The argument was
that old forests have dead trees in them that give off carbon. That’s true, but
it proved to be irrelevant at the landscape scale. There’s a difference between
one rotting log on one site and a whole forest that contains many rotting
logs and a lot of living biomass.”
Harmon’s top graph on the opposite page (A) compares projected carbon storage in a modeled forest blown down and then left alone for 300
years with carbon storage under a scheme of clearcut harvests every 50 years.
The unmanaged forest would store on the average almost twice the carbon
over its 300-year life, about 95 megagrams per hectare (a megagram equals
a million grams), compared with about 50 in the managed forest. “Carbon
storage in a forest is not constant, but fluctuates as forests develop,” says
Harmon. “After disturbance, carbon storage goes down for a period, and
then it goes up. In an unmanaged forest, there’s a bigger change, but the
total carbon storage is also higher.”
The lower graph (B) shows carbon flux, or changes in the total store of
carbon. The managed forest would oscillate between taking up carbon as the
trees grew and giving it off with each clearcut harvest. The forest would lose as
much carbon as it gains on each 50-year rotation. Bringing it under management would result in a net loss of carbon of about 45 megagrams per hectare
over a period of 50 to 100 years. Left unmanaged, the forest would take up
carbon at an increasing rate until about age 70. Carbon uptake would gradually
level off, but there would be a net gain of carbon until age 300.
On a practical level, Harmon’s research points out that plantations of
certain ages are indeed carbon sponges, but they don’t stay that way forever.
And as they mature, other, older stands elsewhere on the landscape are being cut. “Older forests do not take up a lot of carbon, it’s true, but they do
store carbon, and when those forests are cut, much of it is released to the
atmosphere,” Harmon says.

In sum, says Harmon, any strategy to use forests to absorb atmospheric
CO2 must stay mindful of all the growing and dying going on across the
landscape, including the decomposition of wood products.
Harmon’s findings also indicate that longer rotations could make forests much more efficient at taking up carbon. “If we allowed forests to grow
longer between harvests, and if we left more live and dead trees out there to
drive up the average storage on a site, I think it might be possible to double
the store of carbon in a forested landscape.” Wood volume harvested from
these older forests will also be larger and, in some cases, more valuable.
Longer rotations could cost landowners in delayed income from their
forests. However, incentives to abate atmospheric CO2 are emerging in some
developed countries, including a market in carbon credits that can be bought
and sold. “These monetary incentives might not completely offset the revenue from cutting the timber,” says Harmon, “but they might ease landowners’ transition into a less-profitable style of forestry.”

PLANTED FORESTS—A NECESSARY DIMENSION OF

they are necessary if the world is ever
to achieve sustainability of forests, trees, and wood fiber. “Sustainability
argues for inclusive thinking,” Boyle says. “Planted forests are essential—we
can’t get along without them”—especially in a country that consumes wood,
and everything else, as lavishly as ours does.
Planted forests, says Boyle, deserve a respected place alongside native
forests in a comprehensive quest for sustainability. A forester and soil scientist, Boyle, a professor in the Department of Forest Resources, is coauthor
and coeditor of the book Planted Forests: Contributions to the Quest for Sustainable Societies. The book arose from a 1995 conference Boyle helped organize and to which he contributed the opening paper, wherein he set forth
the need for planted forests and the many benefits they provide around the
world.
Fellow scientists and foresters from 13 countries contributed chapters
on the philosophies underlying planted forests, the technologies used to
create and manage them, and practical experience with planted forests in a
wide range of ecological, social, and economic settings.
Boyle, son and grandson of Iowa farmers, was raised in an environment
of practical land stewardship. “I grew up learning that there is a very close
relationship between human welfare and good stewardship of the land,” he
says. Educated in forestry at Iowa State and Yale, he served on the faculty of
the University of Wisconsin from 1968 to 1973 and then the University of
Michigan from 1973 to 1980. He’s been at OSU since 1981.
It was at Michigan that he became well acquainted with the writings of
another Iowan, Yale student, and Wisconsin professor—Aldo Leopold. As a
Forest Service game biologist and, later, as the patient restorer of a worn-out
“sand farm” in Wisconsin, Leopold, through his writings, became a prophetic voice for the conservation and environmental movements taking shape
after World War II.
It was Leopold’s breadth of vision, taking in both the ecological and the
economic aspects of the human-land relationship, that resonated with Boyle’s
own thinking about people and forests. “Within his vision of sustainability
of the land,” says Boyle, “Leopold includes the need to account for human
use and human economics. My forestry education was not at all biased toward timber production; it was a well-rounded scientific education with a
broad ecological vision. But I also realized that we’re all dependent on wood,
and it’s got to come from some place.”
At Michigan, Boyle was looking at the sustainability of the soil resource—
specifically, what happens to the soils of second-growth hardwood and aspen forests when whole trees are logged and removed to make chips, compared to what happens when trees are logged and processed on the site and
the slash left to return to the soil.
Whole-tree harvesting doubles the loss of biomass, but that impact has
less-severe consequences on some sites than on others. “My work on soils
and harvesting impacts led me to understand that there’s a tremendous range
of resiliency in the capacity of soils to sustain ecological processes under
intensive management.”
In other words, intensive forestry may not be a good idea everywhere,
but it works well in some places—perhaps many places. Boyle draws an
analogy to farming: “We have tried intensive farming for a long time, and
in many places it works well,” he says. “We don’t ask ourselves the question, ‘Should we have farming?’ but ‘What kind of farming should we
have, and where?’ We should be asking ourselves the same questions about
forestry.”
Boyle arrived in the Northwest in the early 1980s and joined the OSU
faculty in 1981 as head of the Department of Forest Management (as it
then was called). By the late 1980s, he says, the idea that planted forests
have an important place in forestry did not seem to be getting much attention from policymakers.
37
When the subject of ecosystem management began to preoccupy the
Forest Service and other land-management agencies, “planted forests were
hardly mentioned in any discussion.” Most scientists and policymakers were
focusing on uneven-aged silviculture and other alternative management strategies in native old-growth forests.
Boyle felt it was time to broaden the conversation. In the early 1990s,
prompted by OSU colleagues Bill Atkinson and Bob Buckman, he began to
organize the 1995 symposium. “We had significant discussion among ourselves about what to call this conference,” he says. “We knew there’d be
people who would argue that a forest can’t be planted.”
Yet the nearest alternative, “plantation,” hardly seemed to fit. A plantation, says Boyle, connotes trees lined up in rows and columns, neat as a
cornfield. But in the Douglas-fir region of the Pacific Northwest and many
other parts of the world, planted forests are quickly colonized by other species, eventually developing a complexity of species and structures that makes
them belie their label. So, Boyle says, “‘planted forests’ it was.”
The conference, held in Portland, drew more than 200 people from
around the world to explore the utility and diversity of planted forests. The
subsequent book, published by Kluwer Academic Publishers, may be ordered from the OSU Bookstore.
Along with his undergraduate class in forest ecology, Boyle teaches a
university-wide class in conservation issues in natural resource management.
He introduces the students to Aldo Leopold’s ideas and their sometimesuncomfortable implications about human impacts. He also continues his
research on the effects of harvesting on soils and potential sustainability,
and he has recently assumed leadership of the forest-site working group of
the International Union of Forestry Research Organizations (IUFRO).
“We can’t sustain large-scale consumption around the world at the rate
we’re consuming in the United States,” Boyle says. “And because we all consume, we all participate in the dilemma. I tell my students, ‘I hope you will
begin to think about your role in these issues in a different way.’”
Planted forests, he says, “are an essential part of any thorough strategy
to achieve global sustainability.”

WHAT IS THE ROLE OF PRIVATE
FORESTS?
“What unique social, economic, and
ecological roles do private forests play in
our fast-changing landscapes?”
W
hen most people think of Oregon’s forests, they may picture either national
forest lands, with generally big, old trees,
or expanses of private industrial forestland, with evenaged, younger stands.
What may be less obvious is the mosaic of forestland owned by nonindustrial private forest (NIPF) owners. These smaller parcels tucked in amid public and
industry lands make up 17 percent of Oregon’s total John Bliss explores the
forest land. Because many are the legacy of nineteenth- complicated dynamics of
private forest land ownership.
century homesteads, they are more likely than other forest ownerships to be located along waterways—politically volatile territory in
light of current concerns about watershed health and fish habitat.
The owners are a diverse group of people—farmers, ranchers, investors,
descendants of homesteaders, urban escapees, and many others—with a diverse set of motivations for owning forest land and diverse approaches to
forest stewardship.
It’s important to understand what is happening on nonindustrial private forests, says John Bliss, because owner decisions make a big difference
in whether these forests are healthy or stressed, whether they stay in a forested condition or are converted to some other use.
Bliss is a Forest Resources professor and holder of the Starker Chair in
Private and Family Forestry at OSU. “These forests don’t exist in a vacuum,”
he says. “They fit within a landscape, and that landscape includes the social
and psychological dimensions of human behavior.”
The number of acres owned by nonindustrial forest landowners in Oregon has decreased in recent decades, while the number of owners has increased. To some researchers this suggests a trend of smaller parcels receiving less-efficient management, but another statistic complicates the situation: Between 1961 and 1994, about 763,000 acres of nonindustrial private
land in Oregon were acquired by private industry.
39
40
“The dimensions of the nonindustrial private forest resource are constantly changing,” says Bliss. “Across the nation, NIPF lands at the urban
fringe are being broken into smaller and smaller parcels and converted to
residential and commercial uses. Central to my interest is the question, ‘What
unique social, economic, and ecological roles do private forests play in our
fast-changing landscapes?’”
In trying to understand the dynamics of nonindustrial forest ownership, Bliss and his graduate-student colleagues are exploring questions that
link the natural and social sciences. Why do nonindustrial owners make the
management decisions they do? How do these decisions play out on the
landscape? How do past management decisions affect what the forest landscape looks like today? How do nonindustrial owners get along with their
federal, state, tribal, county, and industrial neighbors?
Studying the interplay between humans and their landscape requires an
approach from several angles—a concept known as “triangulation” in the
world of social science, from which many of Bliss’s research methods are
drawn.
Bliss’s student, Brooks Stanfield, used triangulation in a recent case study
exploring ownership and forest cover patterns in the Coast Range. Using a
method from the social-science side, Stanfield interviewed landowners on
watershed history and local knowledge and values. He and Bliss used information from these interviews, analyzed and sorted according to theme, to
trace patterns on today’s landscape back to historical changes in forest ownership and management.
Stanfield and Bliss also chose a quantitative approach that used GIS
and a computer model known as FRAGSTATS to analyze forest cover in 66
Coast Range watersheds. Stanfield identified and mapped forest cover by
age and dominant vegetation species, delineating the sizes and contours of
patches and the locations and sizes of forest edge and interior. He and Bliss
used these data to explore the relationship between forest ownership and
forest habitat diversity.
“Brooks and I found that, yes, there is a significant link between ownership patterns and forest habitat diversity patterns,” says Bliss. They found
that ownership explains some 38 percent of the variation in forest habitat
diversity in the Coast Range. Nonindustrial private forests, for example,
tend to be widely diverse in age and forest cover, and more fragmented in
terms of habitat than either public or industrial lands. They also contain a
higher proportion of hardwoods (which is partly explained by their morefrequent situation along streams).
“The message,” says Bliss, “is that ownership matters. Different ownership classes—nonindustrial, industry, and public—make different contributions to habitat diversity.” The contribution of each to a particular watershed is related to how much forest land each class owns and where that land
lies on the ground within the watershed.
Another of Bliss’s students, Stefan Bergmann, is using social-science
methods to find out what factors lead to cooperation—or conflict—among
neighboring public and private landowners in the John Day Valley. In the
study area, private ranchers and forest landowners live and work next to the
Malheur National Forest. Bergmann is interested in how these neighbors
cooperate, or don’t, on prescribed-fire efforts.
Bergmann is using a controversial social-science method known as Participant Action Research, or PAR. In PAR the researcher tries to become part of the
community he or she is studying—to the point of allowing the community’s
opinions and information to shape and refine the research questions.
“PAR has its detractors,” says Bliss, “because if you’re not careful you
can compromise your objectivity and fairness.” But properly used, PAR can
lead to the most useful and interesting information. “Typically we researchers think we are the best qualified to determine the research questions. But
by getting involved with the people you’re studying, you allow yourself to
be led to the questions that are really relevant—questions that you might
not think of at the outset.”
With the help of a research fellowship from the Ford Foundation’s Community Forestry program, Bergmann plunged into his work last summer,
interviewing land managers and local officials, observing meetings, listening to oral histories, digging through archives, and taking part in community gatherings.
On a day when Bliss was visiting, he and Bergmann started the day with
a ride in a local citizen’s private airplane—an informal (and informed) aerial
survey of where all the ownership parcels lay, whom they belonged to, and
where and when range fires and forest fires had occurred. “We spent the rest
of the day in interviews,” says Bliss, “and then we ended with a community
potluck supper.”
While Bergmann’s results are still preliminary, he did find “a very high
level of frustration” with the Forest Service among neighbors, Bliss reports.
“There were many beefs—too much Federal management, not enough Federal management, a revolving door with managers coming in and out, policy
confusion.” Bergmann’s analysis should help explain some of that frustration, and perhaps even help the John Day neighbors work out a more harmonious relationship.

THE SERVICES OF WOOD
“Why do trees have the amount of
sapwood they do? How much sapwood is needed to transport the
water? Is there some other service
sapwood is providing to the tree?”
E
42
verybody knows that trees are made of
wood, but what does the wood do for the
tree? Barbara Gartner, biologist and Forest Products associate professor, has some answers. “It may seem odd to say that wood provides services to the tree, but that’s exactly what
it does,” she says. Transporting and storing waBarbara Gartner explores the

and store nutrients and helps it defend itself
against injury and insect attack.
Among conifer species, these various functions are performed by different types of wood in the same tree. “In softwoods, 93 percent of the cells are
responsible for mechanical and hydraulic support,” says Gartner. That is,
they both help the tree transport water and help it stand upright. These cells
are called tracheids. The remaining 7 percent of cells, called parenchyma
cells, store nutrients and sugars and provide the tree’s defenses against disease and injury.
Structural support provided by the tracheid cells is not uniform—it
gets better as the wood grows out from the slender pith at the very center.
Tracheid cells in the newer wood, added in yearly growth rings just under
the bark, are thicker-walled than are those closer in, and so they provide
better mechanical support. They also transport water better under ordinary
conditions (although less well in drought conditions).
For these and other reasons, a tree’s wood varies quite a lot in mechanical and structural properties. These differences are of great interest to manufacturers of wood products, because for almost every application, the more
uniform the structural characteristics of the raw material, the better the
quality of the product.
Gartner is trying a variety of experiments to find out why a tree produces the types of wood it does, and why these types appear when they do in
the life of the tree. Her work could ultimately lead to silvicultural strategies
to fine-tune tree growth to produce more wood with a particular set of
qualities—making it possible to cultivate raw material targeted toward a
particular product.
She is investigating, among other
things, the formation of sapwood—the
outer shell of wood under the bark—
to which a growth ring is added each
year. A mature Douglas-fir tree carries

Douglas-firs, about 200 years.
How does sapwood function in
the life of a tree? “Different tree species have enormous variability in the
amount of sapwood they have,” says Gartner. “But why do trees have the
amount of sapwood they do? How much sapwood is needed to transport
the water? Is there some other service sapwood is providing to the tree?”
Because most of the water in a tree is transported by its sapwood, “the
amount of sapwood in a tree is directly tied to how much water the tree can
transport,” says Gartner. However, as we have seen, sapwood of different
ages varies in its water-transport capability. Sapwood is also important in
holding the tree up, and that represents a tradeoff in water transport: “The
strongest cells for mechanical support are the ones least capable of transporting water in drought conditions.”
All a tree’s growth functions are extremely dependent on the environment
in which the tree is grown, says Gartner. “Soil, rainfall, insect populations, wind,
sunshine, slope, aspect—all these are related to the tree’s structure and function.” Gartner’s work is aimed at clarifying and quantifying these relationships.
43
44
Leaf area, for instance, is a major indicator of many growth functions. A
tree’s capacity to transport water is directly related to leaf area, because it is
from the leaves (needles), that water evaporates. “How much leaf area is
there in proportion to sapwood volume? If there are more leaves, is there
more sapwood? What is the relationship between sapwood volume and root
area?” To help answer these questions, she is drawing not only on her own
measurements but on a large body of research by College of Forestry colleagues Barbara Bond, Dick Waring, and Doug Maguire, among others.
In another line of inquiry, Gartner is studying juvenile wood, a littleunderstood component of softwood species. As the name implies, juvenile
wood is the first wood a tree grows, and so there is more of it in younger
trees. The trunk of a typical 15-year-old Douglas-fir tree is entirely composed of juvenile wood. At age 65, that same tree will contain perhaps 40
percent juvenile wood. The proportion will become smaller over the years
as the tree keeps adding mature wood at the outside, although juvenile wood
continues to grow at the tip.
Thus, there is juvenile wood at the heart of every softwood tree, and
this wood is structurally very different from the mature wood added later.
Juvenile wood is less dense, and its cellular structure is weaker. The tiny
fibers in its cell walls, called microfibrils, are arranged at a 45-degree angle,
diagonal to the cell. In mature wood, the microfibrils are lined up along the
length of the cell. “Imagine taking hold of both ends of a Slinky and pulling
the whole thing apart,” says Gartner, “and then just pulling on a short stretch
of the coil. The short stretch of metal doesn’t give nearly as much. That’s like
the difference in strength between mature and juvenile wood.”
Juvenile retains its weaker properties even as the tree grows old. When
most harvested trees were taken from older forests, the presence of juvenile
wood was of little concern. But these days, trees for structural wood products tend to come from younger, planted forests. They are harvested at a
younger age than in years past: 60, 50, or even 40 years.
“As rotation ages get shorter,” says Gartner, “trees are harvested when
they’re smaller, and they contain a larger proportion of juvenile wood.” That
can present a problem for wood quality. “It’s a common complaint that
studs aren’t what they used to be,” says Gartner. “They aren’t as strong, they
warp—the reader will know all about that.”
Gartner is trying to determine how juvenile wood is formed, when it
stops being produced, and what function it performs for the tree. Her early
findings suggest that juvenile wood may be especially good at protecting the
young tree and the tree tip from drought. “Seedlings don’t have much water
storage capacity, so they are, in effect, in a drier environment than a mature
tree growing nearby.”
Gartner conducted measurements and found that, under dry conditions, juvenile wood conducts water to the top of a tree better than mature
wood does. “So we may find that the tree needs a certain proportion of
juvenile wood” to help it survive and grow in a variety of environmental
conditions.
“If we can find out why the plant is making juvenile wood,” Gartner
says, “then we may find silvicultural ways to hasten the maturing process,”—
or, alternatively, find good reasons to let the tree pursue its own maturing
strategies.
Ultimately, Gartner’s research will help silviculturists better understand
how certain manipulations of a site will affect the quality of the wood in the
trees growing there. Her findings will help managers encourage trees to produce more of the type of wood desired for the final product, or produce it
sooner.

instrument specially
developed to test adhesives.
“The internal structures of bones or trees or insect shells are elaborate—they involve complex mixes of cells of different
types and different orientations,” says Philip Humphrey, associate professor
of Forest Products at Oregon State University. Humphrey believes the concept of bone structure will someday lead to a revolution in the materials
used in buildings, cars, and even aircraft.
Trees, like bones, are sophisticated pieces of natural engineering. Each
cell is shaped and oriented to perform a specific function. Cutting a 2 by 4
is thus a rather inefficient way of using a tree’s cells. “When we cut a board,
we violate the tree’s structure and end up with a product which is highly
variable. As a result, we have to be conservative in estimating how much
load it can bear.”
Humphrey’s research could eventually lead not only to savings in manufacturing costs, but to the development of more-effective materials that are
also kinder to the environment. These improvements could come about
through a shift from using metals to using wood composites for a wide
range of applications.
Currently, Humphrey is looking for ways to take advantage of wood’s
natural strength by efficiently arranging the fibers in composites—matching form to function as elegantly as bones do. But Humphrey didn’t grow
up expecting to be a scientist. He spent his teen years in England building
clavichords, lutes, and harps. Learning about wood at university, he thought,
would help him make better musical instruments. Although he soon found
the research itself exciting, his early interests haven’t been wasted: “Designing and making things is a good foundation for being creative in research.”
Humphrey’s plans for the future have emerged from his experience with
traditional wood composites. Composites are made from fibers, flakes, wafers, or strands of wood bonded with small amounts of glue in processes
involving both heat and pressure. “Making composites,” Humphrey points
out, “is a way of taking a natural material—wood—and finding out how to
make the best use of its attributes. It’s not just using it, but making something new from it.”
When Humphrey began his career, little was known about the physics
of making composites. His doctoral work led to the development of mathematical models that described changes in heat and gas movement during
the wood–adhesive bonding process. This work puts the manufacture of
wood composites on a scientific footing. “The physics is very complicated,”
Humphrey explains. “It’s important to know the speed at which the bonds
develop strength and how the fibers squeeze together.” If these processes are
not understood, the changes that occur with heat and pressure can cause so
much internal stress that the panels are damaged or blown apart. To examine these changes, Humphrey has developed an automated bonding evaluation system (ABES) that measures the effects of time, temperature, and pressure on the development of bonding strength.
In Humphrey’s laboratory, elegantly constructed machines line the
benches. Each of these miniature, automated gadgets tests some aspect of
wood or glue strength. To test a bond, Humphrey glues together the ends of
two wafers, each about half the size of a Popsicle stick, and punches some
numbers into a laptop: “Let’s try 40 seconds at 110 degrees C.” Inserting
the dry end of each stick into a small clamp, he flips a switch on the ABES,
and the miniature pressing plates move to squeeze and heat the glued connection. In 40 seconds, the heating stops and the pressure is released. Gently, the clamps tug the sticks apart. Almost immediately, the bond fails and
the sticks separate with a little hiss. A graph on the computer records the
action.
Each of these tests produces new data on heat or gas movement within
a tiny subdivision of the bond, as well as measuring its strength. Because
each property is affected by every other factor, the data points multiply fast.
“We’re looking at the bond’s hygro-thermo-visco-elastic properties,”
Humphrey explains. “That is, how heat, moisture, and pressure affect the
speed of strength development.”
47
48
The interest is not just academic. In the wood-products industry, panels
are produced in continuous presses costing $150 million that turn out the
equivalent of about twenty 4- by 8-foot panels a minute. Consequently,
production speed is critical. Humphrey’s mathematical models of the intricacies of bonding behavior and composite pressing aim to improve the efficiency of these machines.
It is the prospect of developing revolutionary new products, however,
that excites Humphrey the most—products inspired by bones, trees, and
insect shells. Like natural structures, the new products would have both a
specific external shape and a complex internal structure. Envisioning such
products is a form of biomimetics—borrowing ideas from nature. “We’re
not copying the bones, but we’re using the philosophy of bones to control
shape and to micromanage internal structure. We use mathematical models
both to identify what we should make and to find ways of making it.”
The new products would overcome the problem of passive fibers in
existing wood-based composites; the fibers fill space, but their particular
strengths aren’t used efficiently. No matter what fibers are used, their arrangement is crucial. “The challenge is to assemble the fibers so they work
for us. They need to bond in such a way that each contributes to the strength
and stiffness of the product.”
It’s an awareness of these shortcomings that inspires Humphrey’s goals
for the future; what’s been learned from conventional composites will help
with the formulation of new ones. Eventually, new products from natural
fibers could replace some of the load-bearing parts used in aircraft and other
products. Each piece would be individually designed, with computers
reconfiguring the same machines to produce different parts. “With this new
approach, we’re aiming for products highly tailored to particular uses—
products that are environmentally better and more efficient than other materials such as aluminum alloys,” says Humphrey. “What we’ll be forming
are objects designed to perform very specific functions very efficiently, rather
than commodity products which can be used in a lot of situations with only
moderate efficiency.”
Humphrey is particularly attracted by the idea of creating substitutes
for the metal alloys used in planes and cars. “The environmental impact of
using alloys is great. Smelting ore uses large amounts of energy and produces toxic wastes. Composites from natural fibers are much more environmentally friendly and can be assembled to perform as well or better structurally.”
Developing these new products is more than just a dream. Humphrey’s
group has already created prototypes in the lab, and initial demo products
might include a load-bearing part of a car suspension or steering system.
Ultimately, the goal is to make the most efficient use possible of natural
resources. “If we’re going to use wood from forests, we’re morally bound to
use it efficiently.”

John Simonsen: improving the
performance of wood-plastic composites. you’re in a Ford Thunderbird, notice the
little shelf on which you rest your elbow. It’s made of wood. More precisely,
it is made of a material called a wood-plastic composite.
More and more, nonstructural products like car door panels and trim,
home window frames, and porch railings are being made from plastic mixed
with ground-up bits of wood. Both the plastic and the wood often come
from recycled materials—discarded wooden pallets and plastic milk jugs.
Combining these materials offers a way to reduce waste of natural resources, make more use of recycled materials, and fill certain market niches
better than either pure wood or pure plastic materials.
Wood-plastic composites, says John Simonsen, have lately become a
hot marketplace item as new products and new applications have been developed in the last several years. An industry trade journal estimates that the
total production of wood-plastic composites tripled from 1997 to 1999.
“It’s still a small part of the market,” says Simonsen, “but it’s growing at
about 40 percent a year.” Simonsen, a professor in the Department of Forest Products, is a chemist whose research is helping to make wood-plastic
composites stronger, stiffer, and easier and cheaper to manufacture.
The idea of adding wood to plastic to enhance its structural properties
is not new. Bakelite, the very first commercially developed plastic, had wood
fiber as part of its mix back in 1907. Over the years, many materials have
been added to plastic as “filler,” but wood is a particularly good one, says
Simonsen. Wood fiber adds strength and stiffness to plastic. It makes the
final product lighter in weight and, in some cases, faster to manufacture.
For its part, plastic adds something to wood: resistance to rot and insect
damage, and ease of manufacturing.
Wood-plastic composites are best suited for nonstructural products like
panels, molding, window frames, picnic tables, and highway signposts. They
turn up in some less-likely products, too, like drumsticks—the musical variety. “I’ve heard that the all-plastic ones are too floppy and all-wood ones
are too dull-sounding,” says Simonsen, “but that these are just right.”
Composites do not work well for structural uses, and for that reason
they’ll probably never replace dimension lumber, Simonsen says. The closest thing to a structural product commercially available now is wood-plastic
composite decking. It resists mold, rot, and staining (although it is not impervious), but it can’t compete with real lumber for strength and stiffness.
Try to use it like conventional lumber, and you’ll get “creep”—the propensity of plastic to be malleable; to sag, twist, and otherwise lose its structural
integrity.
As a chemist, Simonsen is interested in the interface between plastic
and wood, two very different materials: “Scientifically, that’s where the action is.” In general, wood attracts water (it’s hydrophilic), while plastics
repel water (they’re hydrophobic). So making composites is “like mixing oil
and water,” Simonsen says. “You have to get them to stick together, and
they don’t easily do that.”
Simonsen and his colleague, Kaichang Li (Forest Products), are working on ways to create hybrid molecules, half wood and half plastic, in the
lab. Adding small amounts of these molecules, called “compatibilizers,” to
the composite mixture helps the ingredients blend better. It also greatly
improves the strength and stiffness of the product.
Molecules of this sort have been developed in other laboratories to help
blend different types of plastics, says Simonsen. “We’re taking molecules of
polypropylene and ‘grafting’ another chemical to it. For reasons not well
understood, these hybrid molecules make wood and polypropylene mix more
easily.”
Another interesting problem is how to make a pure plastic surface material stick to a wood-polymer base. Molded countertops and similar products are now made with pure wood bases. Simonsen and his Forest Products
colleagues are working on better ways to bond the tops to the bottoms.
“The adhesion is done in a hot press, and now the press tends to melt the
51
plastic.” The work involves both adhesive chemistry and trials of different
application processes.
Wood-plastic composites, says Simonsen, are a very practical way to
improve the stewardship of natural resources. “If we’re going to provide the
standard of living people want with the resource base available, we’re going
to have to do more with less. Using recycled plastic and recycled wood to
make new materials and new products is a way to achieve that.”

THE HUMAN FACTOR
Deciphering people’s feelings about
and attitudes toward the land may be
the most difficult as well as the most
important task facing forest managers
in this new century.
F
orest managers know a lot about how forests function, and their knowledge is growing. They can even make reasonable projections about what a forest will look like in the
future if certain management practices are followed today.
What they cannot predict with much success
is how people will respond to those management
decisions. The human factor can make all the dif- Bruce Shindler: What do people

on forest lands?
out forest practices successfully.
What makes a particular forestry practice acceptable or not? Bruce
Shindler, associate professor in the Department of Forest Resources, is using social-science research methods to get at this most elusive of questions:
What do people find acceptable and appropriate on forest lands, and what
factors influence their judgment? “There is a gap in understanding of the
full range of social factors and how they fit into natural-resource management,” Shindler says.
This gap has caused no end of trouble between forest managers—both
public and private—and the people to whom their decisions matter. Natural-resource debates have been called “wicked” problems because they are
too big and complex to be solved by top-down technical analysis. “Wicked
problems are interrelated ones of organized complexity that cannot be solved
in isolation from one another, but also hinge on differing sociopolitical values that clash in the political arena,” wrote Shindler and coauthor Lori Cramer
(OSU Department of Sociology) in a recent article in the Western Journal of
Applied Forestry.
But it is not enough to throw up the hands, as frustrated forest managers
have been tempted to do, and declare such problems unsolvable. Social-science
53
54
techniques are proving useful in understanding the patterns that exist in public
attitudes and citizen behaviors about natural-resource management.
Although not as reliable as measurements of ecological processes, says
Shindler, social assessments can provide valuable information about the various
“publics” managers encounter. A better understanding of how and why people
accept—or reject—natural-resource management strategies will help resource
professionals make more effective, and ultimately more durable, decisions.
In his newest study, Shindler and colleague Mark Brunson of Utah State
University are evaluating public responses to certain ways of treating fuels
in fire-prone forest and range settings, particularly lands at the urban fringe.
They are using surveys, focus groups, interviews, and other social-science
research methods to illuminate how, and under what circumstances, people
decide whether prescribed fire, thinning, mechanical mowing, and other
treatments are acceptable or not.
Because the human dynamic is complicated, decision pathways are not
easily elucidated, Shindler says. “Nor can we count on social processes being
replicated. You can’t just make up a checklist and feed it into a computer
model.” In fact, this common assumption of scientific methodology may be
part of the problem when it comes to the human factor. Researchers and
managers sometimes assume that good science alone will guarantee a good
forest plan. But many wicked natural resource problems hinge on managers’
and citizens’ different ways of seeing the world.
“For example, ‘landscape,’ to a forester or an ecologist, usually means a
place where the traditional boundary of the forest stand or watershed has been
expanded to take in a range of biophysical and geological processes,” Shindler
says. “But to lay people, a landscape is often a particular place with well-defined
boundaries, one that has meaning for them apart from its physical processes.
For example, forest places often have an identity among local communities, and
people are concerned about maintaining access to the site for the activities they
currently enjoy.”
In other words, people hold powerful feelings about a place that a mere
biophysical definition of “landscape” does not begin to capture. These personal forms of knowledge about place are hard to incorporate into management plans based on scientific and rational knowledge. Traditional landmanagement agencies often have difficulty knowing what to do with such
“squishy” information, says Shindler. A one-size-fits-all management plan
that does not take people’s personal meanings into account runs a high risk
of being judged unacceptable by those people most affected by it, and thus
becoming the target of extended debate.
For that reason, an awareness of context is crucial, says Shindler. “Not
only the spatial context—how big an area are we managing?—or the temporal—what will this landscape produce over time?—but just as importantly, the social and political context.” Contextual questions involve the
unique characteristics of the place, how the land has been managed over
time, and the expectations of the community for allocation of the resources.
For example, a management plan is more likely to be acceptable to the
public if its framers consider questions like these: Who lives nearby, and
who lives farther away, and how do their interests merge or diverge? How
will decisions about the forest’s future be made, and by whom? What are the
risks and costs of treatment alternatives? Who wins and who loses in different management scenarios?
The quality of the decision-making process is also important in whether
decisions are acceptable to the public, says Shindler. If citizens perceive that
the process is open and fair, that they have enough information to make real
choices, that their concerns are taken seriously, and that decisionmakers are
genuine and trustworthy, then they are more likely to accept the decisions
that emerge.
It may seem that the natural resource management arena is nothing but
a battleground. “As scientists studying the social side of resource management, I sometimes feel we cast ourselves in a doomsday role, pointing out
all the problems,” says Shindler with a smile. “But we’re also finding many
examples of positive interactions between citizens and resource managers.
We’ve found common elements across settings that are helping us establish
a core set of criteria for public acceptance of management practices.”
Some of those successful elements were identified by Shindler and colleague Julie Neburka in a recent Journal of Forestry article on public participation in forest planning. Among them are selecting committed participants, encouraging full group interaction, clearly defining the group’s mission, making the decisionmaker a regular and full participant, disseminating current and reliable information, defining key terms, answering questions promptly and directly, and tending to such “care and feeding” touches
as providing drinks and snacks at long meetings to show participants that
their efforts are valued.
Deciphering people’s feelings about and attitudes toward the land may
be the most difficult as well as the most important task facing forest managers in this new century. From a research perspective, social scientists like
Bruce Shindler are playing a significant role in helping land managers arrive
at lasting, acceptable decisions.

A glance at the graph of research expenditures on the following page
shows that the bulk of the Forest Research Lab expenditure comes from
grants and contracts from funding agencies and organizations outside the
University. Many of these grants are awarded to faculty members through
competitive selection, and for most of them the competition is stiff. FRL
researchers have been consistently rated first among those at all U.S. universities in obtaining outside funding for forestry and forest products research.
Success in this arena makes the FRL a vital center for all kinds of research in
many forestry-related disciplines. All this research ultimately contributes to
better stewardship and sustainability of our nation’s forests.
Of FRL research expenditures from these outside grants and contracts,
about 65 percent derives from Federal sources, and about half of that amount
comes from the U.S. Department of Agriculture. The U.S. Department of the
Interior and the National Science Foundation are the other principal Federal
contributors to FRL grant-and-contract research. Other funds are provided by
the National Aeronautics and Space Administration (NASA), the U.S. Department of Energy, and the U.S. Environmental Protection Agency.
FRL research is directly supported by Federal appropriations under the
McIntire-Stennis Cooperative Forestry Research Act, which provides research
funds to states on the basis of a formula that considers forest land area, annual
timber harvest, and nonfederal funds provided for research. FRL research also is
supported by a direct appropriation in the State’s biennial budget.
The forest-products industry supports FRL research through the Oregon
Forest Products Harvest Tax, levied on all timber harvested in Oregon and dedicated in part to FRL research. Individual companies participate in FRL research
also through industry memberships in the FRL’s several research cooperatives
and through direct research contracts. The State of Oregon and the Federal
government also participate beyond their direct appropriations through membership of some natural-resource agencies in research cooperatives.
These various sources of funds reflect the diverse research concerns of
the FRL’s broad constituency. But our stakeholders share a common concern about good stewardship of forests. The starting point for good stewardship is good science. It is that essential fact that gives our research programs shape and purpose.

The Forestry Media Center has been producing and distributing videotapes (VT), films, and slide-tapes (S-T) since 1972. More than a million students in educational institutions, government agencies, and private industry throughout the world
have used these audiovisual programs for training and education. Although most of
the programs have been prepared for professional foresters and forestry students,
many are of interest to small-woodland owners, high school classes, other special
groups, and the general public. In the past two years, specialists from the College of
Forestry have completed two new programs. The Center now has over 123 presentations available for purchase or rent. For a complete listing, please contact:

The forest products industry employs over 1.4 million people in the United
States; it ranks among the top 10 manufacturing employers in 46 states. However,
few educational programs about forestry and forest management are targeted at this
audience. As a result, employees are often no better acquainted with forestry issues
than the general public.
Project FLOW (Forestry Learning Opportunities for Workers) is the product of
a cooperative effort between Oregon State University’s Forestry Media Center and
the Oregon Forest Resources Institute. Its purpose is to increase the basic forestry
knowledge of Oregon’s forestry workforce.
Project FLOW is a set of teaching packages with the following components:
•
www.forest learn.org — A website that presents objective information on forestry issues in a lively and timely manner.
•
”Oregon Forest Journal” — a video magazine whose Issues in the Forest segments
address forestry issues in brief, compelling short episodes. The Faces of Forestry
provide an additional human interest story highlighting forest products workers
and activities in natural resources.
•
Vol.1, “Looking for a Clearcut Answer,” focuses on clearcutting, exploring why
and when foresters use this often-controversial silvicultural tool. (1170 V-T)
•
Vol 2., “Habitat, Sweet Habitat,” looks into some of the science of wildlife habitat and explores what foresters are doing to protect the abundance and diversity
of wildlife in our managed forests. (1171 V-T)
Each video is accompanied by a viewer summary, presenter’s guide, and other
support materials.

West-side forests in Oregon and Washington are increasingly dominated by dense
young stands as a result of decades of timber harvesting. The Endangered Species
Act and the Northwest Forest Plan have focused attention on biodiversity within
these stands. The Young Stand Biodiversity Project compared vegetation and fauna
in young thinned, young unthinned, and old-growth stands on BLM lands. In this
program, researchers who studied birds, moths, lichens, bryophytes, and understory
vegetation discuss their findings and possible implications for future management
of young forests.

The Forest Research Laboratory, in cooperation with other departments and units
in Oregon State University’s College of Forestry, offers an extensive array of continuing higher education and technology-transfer events, training workshops, short courses,
and conferences each year through its Outreach Education Office. Participants come
from a broad spectrum of the forest community, including mid-career silviculturists
and forest professionals, forest technicians and practitioners, mill managers and supervisors, logging specialists, contractors, other natural resource specialists, industry foresters, and private landowners. The mission of the Outreach Education Office is to
provide high-quality programs to meet the educational needs of natural resource scientists and professionals and to enhance public understanding of natural resources.
During the 1998–1999 and 1999–2000 academic years, 66 courses were offered and attended by a total of 4,537 people. All courses were carefully budgeted to
be fully supported by participant fees or outside grants and contracts.
Courses offer participants up-to-date forest research information and training
and a forum for discussing and evaluating current forestry issues. They also keep
open a vital channel of communication about application of the Laboratory’s research findings and future research needs. Many programs are cosponsored by other
forestry and natural resource agencies and organizations, providing further links
among users of research information.
