Abstract
During 1999-2000, the fifth inventory of West Virginia’s forest resources was
conducted by the Forest Inventory and Analysis unit of the USDA Forest Service’s
Northeastern Research Station. The survey included a subsample within the
Monongahela National Forest (MNF). The results showed that the MNF contains
899,000 acres of forest land, or 7.5 percent of the State’s total forest land. Mature
forests dominate the landscape within the MNF, timber quality is high, and average
annual growth to removals is positive—a ratio of 3.6 to 1. Species composition on the
Forest differs from that of the State as a whole. For example, nearly 80 percent of the
volume of red spruce in West Virginia grows on the Monongahela.

Introduction
Information on the extent, condition, and use of the
valuable resources within the Monongahela National
Forest (MNF) in West Virginia is essential to effectively
manage, protect, and allocate the numerous goods and
services available from the Forest. During 1999-2001,
the fifth forest inventory of West Virginia, was conducted
by the Forest Inventory and Analysis (NE-FIA) unit of
the USDA Forest Service’s Northeastern Research
Station. The survey was carried out under the authority
of the McSweeney-McNary Forest Research Act of 1928
and subsequent legislation, including the Renewable
Resources Planning Act of 1974 and the Renewable
Resources Research Act of 1978.
The NE-FIA unit conducts forest inventories in 13
Northeastern States. The first survey of West Virginia’s
forest resources was conducted in 1949. Subsequent
inventories were carried out in 1961, 1974, and 1989.
The 1999-2001 inventory in the Mountain State was
conducted in cooperation with the Monongahela
National Forest, West Virginia Bureau of Commerce,
and the landowners of West Virginia.
The sampling procedure in the most recent survey was
conducted in two phases, and included a sample of new
and remeasured plots. Satellite imagery was used to
stratify plots into forest and nonforest land-use classes.
This was followed by the establishment of new plot
locations on the ground, and the remeasurement of plots
that had been established during earlier inventories. All
land in West Virginia, including the MNF, was included
in the sample base. Of the 2,541 ground plots established
in the State, 151 plots are on the Forest (Fig. 1).
This report highlights the results of the 1999-2001 survey
as it relates to the MNF. A separate statistical report for
the entire State is available (Griffith and Widmann 2003)
and a detailed report on West Virginia’s forest resources is
being prepared. Also, several associated studies related to
the State’s forests were conducted in conjunction with
this program and NE-FIA’s general program of research.
These include ongoing studies of forest-land ownership
and the timber industry in West Virginia.

Reliability of the Estimates
The data in this report are based on a carefully designed
sample of forest conditions throughout West Virginia.
However, because the field crews did not measure every
tree or every acre in the State, the data are estimates. The
reliability of the estimates can be judged by two
important statistical criteria: accuracy and precision.
Accuracy refers to the success of estimating the true
value; precision refers to the clustering of sample values
about their own averages or to the variation among
repeated samples. We are interested primarily in the
accuracy of the inventory but in most cases we can only
measure its precision.
1
Although accuracy cannot be measured exactly, it can be
checked. Preliminary tables are sent to other agencies and
to outside experts familiar with the forest conditions in
West Virginia. If questions arise, the data are reviewed
and reanalyzed to resolve differences. Great care is taken
to minimize sources of procedural error through careful
training of both field and office personnel, frequent
inspection of field and office work, and application of
the most reliable inventory methods.
Because of the care exercised in the inventory process,
estimates of precision afford a reasonable measure of the
inventory’s adequacy. The precision of each estimate is
described by its sampling error. Sampling errors are
provided in several tables in this report. Additional
sampling error information is available upon request.
The following is an example of how the sampling error is
used to indicate reliability. The estimate of total forest
land for the Monongahela National Forest is 899,000
acres. The estimate has an associated sampling error of
0.5 percent, or 4,495 acres. This means that if there are
no errors in the procedure, we are 68 percent confident
that the true area is 899,000 ± 4,495 acres (at one
standard deviation), or that it is between 894,505 and
903,494 acres. Similarly, we are 95 percent confident that
the true area is 899,000 ± 8,990 acres (at two standard
deviations).
Estimates become less precise with increasing detail, both
spatially and in terms of more specific forest and tree
attributes. For example, while the sampling error for all
forest land on the Monongahela National Forest is 0.5
percent, the sampling error for the area in sawtimber
stands is 4.4 percent, the area in poletimber stands is
17.0 percent, and the area in seedling and sapling stands
is 39.0 percent.
The reason for these higher sampling errors is that as the
size of the sample in a particular condition decreases,
sampling error increases. County estimates were not
provided in this report for that reason. In many cases, the
sampling errors were too large for the estimates to be
meaningful. Estimates with sampling errors greater than
25 percent are suspect, and those larger than 50 percent
2
mean that because the resulting estimate is not
significantly different from zero (at two standard
deviations).
For many of the tables in this report, both the last
column and last row are labeled “SE.” These values are
the sampling errors of the column and row totals. The
last sampling error (SE) given is for the table total. It’s
possible to approximate the actual sampling error for a
table cell within certain tables.
To do so, use the following formula:
NOTE: this formula is reliable only for estimating sampling
errors of individual cells in the area tables.
SEij = 1/Pij((Pij (1- Pij))/n)1/2

Comparison Between Inventories
As a result of ongoing efforts to improve the efficiency of
the inventory, several changes in procedures and
definitions have been made since the previous inventory.
These changes prevent direct comparison between the
current estimates with those published previously. The
changes in methods and definitions include: (1) use of
the official land area of the Monongahela National Forest
rather than that estimated from state-level statistics, (2) a
new plot design, and (3) procedures to calculate levels of
stocking as it relates to stand size and forest type.
New Plot Design
To improve data consistency at the national level, a
standard plot design is being used by FIA units
throughout the country. The new plot design, a cluster of
four 24-foot-radius subplots covering a 1/6-acre area, was
used during the most recent inventory on both new and
previously measured plot locations.
In addition to the new plot configuration, field crews
recorded different conditions on the plot if certain
attributes (land use, forest type, stand origin, stand size,
tree density, owner) differed from those at plot center,
along with information that described the boundaries of
the conditions. This procedure was designed to reduce
bias in the estimates. In previous inventories, ground
plots were assumed to be wholly within the condition
that the plot was chosen to represent.
On all remeasured plot locations, a subsample of trees
that were recorded in past inventories was reconciled,
and growth and removals estimates were calculated using
these data.
Determination of Land Area
FIA uses Bureau of Census estimates of total land area as
the basis for area estimates for states. But between 1980
and 1990, the Bureau changed its estimating procedures.
Previously, the minimum width for streams had been 660
feet, and the minimum area for bodies of water was 40
acres. Now, inland-water streams more than 200 feet
wide and bodies of water 4.5 acres and larger in area are
identified. Changes in this procedure resulted in a
reduction in total land area in West Virginia of 20,600
acres.
This FIA report for the Monongahela National Forest
used the legal total-land area estimate of 910,000 acres
(as of September 2002) to make area estimates for the
Forest. This area estimate is believed to be more accurate
than the estimate obtained from FIA state-level statistics.
Estimates used in this report underestimate the amount
of nonforest land on the Monongahela, because FIA field
crews do not determine ownership of field plots that are
nonforest. The estimate of nonforest area is based on the
nonforest portions of plots where the plot center is
forested.

The 899,000 acres of forest land on the MNF represent
7.5 percent of the forest land in West Virginia. Ninetyone percent of these acres (814,600 acres) are considered
timberland. Timberland acres meet minimum
productivity standards and are considered potentially
available for timber production. Reserved forest land and
“other” forest land are not included as timberland.
Reserved acres represent 8 percent of forest land and
include designated wilderness areas. “Other” or
unproductive forest land represents 1 percent of total
forest land and includes areas not capable of growing at
least 20 cubic feet of wood per year. The acreage of
timberland on the MNF represents 6.9 percent of the
State’s total timberland.

Most Stands are Fully or Overstocked
Timberland on the MNF is well stocked with growingstock trees (trees of commercial importance with good
form). Most stands are classified as fully or
overstocked;— 58 and 8 percent of timberland,
respectively. Trees in these stands are fully utilizing the
site’s potential to grow valuable trees. Stocking levels on
the MNF tend to be higher than those for the State as a
whole. On MNF timberland, the average number trees 5
inches and larger is 175 per acre versus 146 for the State.

The 2000 forest inventory revealed that on an annual
basis, the net growth of trees averaged 25.8 million cubic
feet and harvesting averaged 7.1 million cubic feet. The
net growth of wood, which includes losses due to natural
mortality, was 3.6 times as much as was being harvested.
On average, the growing-stock volume increased by 18.6
million cubic feet (0.9 percent of total volume) per year.

Standard cord. A unit of measure for stacked bolts of
wood, encompassing 128 cubic feet of wood, bark, and
air space. Fuelwood cord estimates can be derived from
cubic-foot estimates of growing stock by applying an
average factor of 80 cubic feet of solid wood per cord.
For pulpwood, a conversion of 85 cubic feet of solid
wood per cord is used because pulpwood is more
uniform.
State lands. Lands owned by the state or leased to the
state for 50 years or more.
Stocking. The degree of occupancy of land by trees
relative to the growth potential utilized by a site. It is
expressed as a percent of the “normal” value presented in
yield tables and stocking quides. Two categories of
stocking are used in this report: all live trees and
growing-stock trees. The relationships between the classes
and the percentage of the stocking standard are:
nonstocked (0 to 9); poorly stocked (10 to 34);
moderately stocked (35 to 59); fully stocked (60 to 100);
and overstocked (greater than 100).

buildings and condominiums) and immediately adjacent
managed land.
Transportation right-of-way. Land associated with
highways and railroads.
Tree class. A classification of the quality or condition of
trees for sawlog production. Tree class for sawtimber trees
is based on their current condition. Tree class for
poletimber trees is a prospective determination—a
forecast of their potential quality when they reach
sawtimber size (11.0 inches d.b.h. for hardwoods, 9.0
inches d.b.h. for softwoods).
13

Whenever a 14- or 16-foot section of the butt 16-foot log is better than the best 12-foot
section, the grade of the longer section will become the grade of the tree. This longer
section, when used, is the basis for determining the grading factors, such as diameter
and cull deduction.
b
In basswood and ash, diameter inside bark at the top of the grading section may be 12 inches
and DBH may be 15 inches.
c
Grade 2 trees can be 10 inches diameter inside bark at the top of the grading section
if otherwise meeting surface requirements for small grade 1's.
d
A clear cutting is a portion of a face free of defects, extending the width of the face. A face is
one-fourth of the surface of the grading section as divided lengthwise.
e
Fifteen percent crook and sweep, or 40 percent total cull deduction are permitted in grade 2
if size and surface of grading section qualify as grade 1. If rot shortens the required clear
cuttings to the extent of dropping the butt log to grade 2, do not drop the tree's grade to 3
unless the cull deduction for rot is greater than 40 percent.

No tree will be designated below Grade 4 unless net tree scale is less than one-third of gross tree
scale.
SOUTHERN PINE TREE GRADES
Grade 1 - trees with 3 or 4 clear faces on the 16-foot grading section.
Grade 2 - trees with 1 or 2 clear faces on the 16-foot grading section.
Grade 3 - trees with no clear faces on the 16-foot grading section.
After the tentative grade is established, the tree will be reduced one grade for each of the following:
(1) Sweep. Degrade any tentative Grade 1 or 2 tree one grade if sweep in the lower 12 feet of the grading
section amounts to 3 or more inches and equals or exceeds one-fourth the diameter at breast height.
(2) Heart rot. Degrade any tentative Grade 1 or 2 tree one grade if conks, punk knots, or other evidence of
advanced heart rot is found anywhere on the tree stem.
NOTE: No tree can be degraded below Grade 3, provided the total scaling deductions for sweep and/or rot do
not exceed two-thirds the gross scale of the tree. Trees with total scaling deductions in excess of two-thirds are
classified as cull.
A face is one-fourth the circumference of the 16-foot grading section and extends the full length of the grading section.
Clear faces are those free from knots measuring more than 1/2 inch in diameter, overgrown knots of any size, and
holes more than 1/4 inch in diameter. Faces may be rotated, if necessary, to obtain the maximum number of clear
faces on the grading section.
One-log trees are graded by using the Southern Pine Log Grades. This is recommended because the entire
merchantable volume of the tree is contained in the graded section. The log grading system gives a more accurate
prediction of the lumber grade-yields for such trees than would the tree grading system.

Although 1,000 board feet are theoretically equivalent to 2.36 cubic
meters, this is true only when a board foot is actually a piece of wood
with a volume 1/12 of a cubic foot. The International 1/4-inch log rule
is used by the USDA Forest Service in the East to estimate the
product potential in board feet. The reliability of the estimate obtained
by conversion will vary with the size of the log measure. The
conversion given here, 3.48 cubic meters, is based on the cubic
volume of a log 16 feet long and 15 inches in diameter inside bark
(d.i.b.) at the small end. This conversion could be used for average
comparisons when accuracy of 10 percent is acceptable. Because
the board foot unit is not a true measure of wood volume and because
products other than dimension lumber are becoming important, this
unit may eventually be phased out and replaced by the cubic meter.

Includes all commercial forest land (500); special forest land such as highly visible sites or study areas where timber harvesting is a minor
management objective (600); land classed as marginal due to high development costs, low product values, or resource protection
constraints (700), lands tentatively suitable for timber production (699); and land classed as marginal due to steep slopes (720).
b
Includes all productive reserved land (300) that is designated as wilderness; productive deferred forest land that is withdrawn for possible
later inclusion as wilderness (400); and all unregulated land not appropriate for timber production (800), reserved for primitive recreation or
special use (810), and either currently excluded (820) or under study for possible exclusion (880) from the regulated commercial forest land
base.
c
Formerly known as unproductive forest land, it includes unproductive (900) and marginal unproductive (740).
e
includes all non forest land reserved from forest use, such as wildlife openings, rights-of way, or land incapable of supporting forests (200).
Because FIA does not collect ownership information on non forest plots these estimates are only from the nonforest portions of forested
plots: This results in an omission error in the estimate for non forest area.

Forest type groups are combinations of forest types that share closely associated species or site requirements. They broadly describe the dominent species
growing on the land. However most forests are composed of many different species, and individual species are not restricted to any single forest type or forest
type group.
b
Sampling Errors (SE) are expressed as a percent of the total and are included for only row and column totals. Cell values with estimates that have an associated
sampling error between 25 and 50 should be used with caution. Cell values with estimates that have an associated sampling error greater than 50 percent are
not significantly different from zero at two standard deviations.

Sampling Errors (SE) are expressed as a percent of the total and are included for only row and column totals. Cell values with estimates that have an associated
sampling error between 25 and 50 should be used with caution. Cell values with estimates that have an associated sampling error greater than 50 percent are not
significantly different from zero at two standard deviations.

Sampling Errors (SE) are expressed as a percent of the total and are included for only row and column totals. Cell values with estimates that have an associated sampling error
between 25 and 50 should be used with caution. Cell values with estimates that have an associated sampling error greater than 50 percent are not significantly different from zero
at two standard deviations.

During 1999-2000, the fifth inventory of West Virginia’s forest resources was
conducted by the Forest Inventory and Analysis unit of the USDA Forest Service’s
Northeastern Research Station. The survey included a subsample within the
Monongahela National Forest (MNF). The results showed that the MNF contains
899,000 acres of forest land, or 7.5 percent of the State’s total forest land. Mature
forests dominate the landscape within the MNF, timber quality is high, and average
annual growth to removals is positive—a ratio of 3.6 to 1. Species composition on the
Forest differs from that of the State as a whole. For example, nearly 80 percent of the
volume of red spruce in West Virginia grows on the Monongahela.
