Appendix I: Fixed Radius Plot
APPENDIX I: FIXED RADIUS PLOT
A fixed radius plot is used to sample trees that are less than the specified breakpoint
diameter. These sample trees are determined to be “in or out” at ground line. If the
measured distance from plot center to the central axis of the tree at ground line is equal to
or less than the fixed plot radius the tree is tallied as a sample tree. If this distance is
greater than the fixed plot radius, the tree is not tallied.
On level ground, the fixed plot radius is determined by holding the measuring tape or pole
in a horizontal position from plot center to the central axis of the sample tree. On slopes
greater than 9 percent, if a measuring tape or pole can not be held horizontally from plot
center to the central axis of the sample tree, the fixed plot radius is corrected for the slope
percent by using one of the following two methods.
1. Correct the fixed plot radius for slope percent using the “Circular Plot Radii Corrected
for Slope” table and then measuring distances parallel to the ground line. This method
always results in a circular plot on the slope.
Example - 1/300 acre fixed plot on 50 percent slope. Corrected fixed plot radius is 7.2 feet.

2. Determine the slope limiting distance to borderline trees by using the “Slope Correction
Table.” (The slope being corrected is the slope from plot center to the tree, not the
overall plot slope.) Measure the distance parallel to the ground line to the borderline
tree. This method always results in an oval plot on the slope. Following is a list of fixed
plot sizes and the specific radius for each:

To determine the slope limiting distance, multiply the plot radius for the appropriate
plot size by the appropriate slope correction factor.
Example 1: 1/300 acre fixed plot with a borderline tree on a 45 percent slope. A
1/300 acre plot equals a 6.8 foot radius and the slope correction factor for a 45 percent
slope is 1.10. 6.8 x 1.10 = 7.48; thus, a tree on a 1/300 acre fixed plot at a 45 percent
slope can be 7.5 feet from plot center.

Region 1
Appendix I: Fixed Radius Plot
Example 2: The same plot has another borderline tree on a 25 percent slope. The
slope correction factor for a 25 percent slope is 1.03. 6.8 x 1.03 = 7.0; thus, a tree on a
1/300 acre fixed plot at a 25 percent slope can be 7.0 feet from plot center.

APPENDIX J: VARIABLE RADIUS PLOT
Introduction
In or out determination is made at the DBH or DRC of each tree. For information on the
theory and mathematics of variable plot cruising; and formulas for determining the plot
radius factor for any given BAF, the reader is referred to Log Scaling and Timber Cruising,
1973, J. R. Dilworth. OSU Book Stores, Inc., Corvallis, Oregon.
The experienced field person using a wedge prism, angle gauge, or relaskop can quickly tell
in most cases which trees are “in” or “out” on the variable plot. However, there are certain
trees that are questionable (borderline) for tally because they are located at the outer
limits of the variable plot radius. This narrative deals with the procedures needed to
ascertain if these borderline trees should be tallied: the mechanics of using plot radius
tables in the field, the associated measurements, and corrections of variable plot radii for
slope.
Measurement of Borderline Trees to Determine “In or
Out” Status
In variable plot sampling, the plot radius varies according to the DBH or DRC of each tree.
Therefore, to determine whether a tree is to be sampled requires measurement of its DBH
or DRC and its distance from plot center. Tables J-1 through J-5 display limiting distances
(the maximum horizontal distance from plot center to the face of the tree at breast height
for a tree to be considered “in”) for various tree diameters and commonly used basal area
factors (BAF).
Once the DBH or DRC of the borderline tree is taken, the limiting distance is found by
entering the table appropriate for the specified BAF. This limiting distance is then
compared to the horizontal distance between plot center and the nearest face of the tree
at breast height. If the measured horizontal distance from plot center is less than or equal
to the limiting distance from the table, the tree in question is “in” and is tallied as a sample
tree. However, if the measured horizontal distance from plot center is greater than the
limiting distance, then the tree in question is “out” and is not tallied.
1. Measure the diameter to the nearest tenth of an inch.
2. Measure the percent slope from the face of the tree at DBH or DRC to plot center.

3. If the slope is less than ten percent look up limiting distance in Tables K-1 through K5 or use the BAF correction factors listed below.

(*This is a corrected plot radius factor, corrected for determining the limiting distance to the face
of the tree. A standard plot radius factor is used to determine limiting distance to the center of a
tree, and is computed by 8.696/SQR (BAF). A corrected PRF subtracts 1/24 (.041666) from the
standard plot radius factor)
Example 1:
BAF =
40
DBH = 20.9 inches
Slope = 5%
Limiting Distance
= Plot Radius Factor * DBH
= 1.333 * 20.9 = 27.9 feet
4. If the slope is greater than ten percent, first determine the slope correction factor.
The slope correction factor and the slope corrected plot radius factor can be obtained
by using the formula below or by referring to Table J-6. Then, multiply the slope
correction factor by the plot radius factor identified in (3) above to obtain the slope
corrected plot radius factor. Finally, multiply the slope corrected plot radius factor by
the diameter to obtain the limiting distance.
Example 2:
BAF =
40
DBH = 20.9 inches
Slope = 20%
Slope Correction Factor
Slope Corrected Plot Radius Factor
Limiting Distance
= SQR (1 + (slope /100)²)
= SQR (1 + (20/100)2
= 1.0198
= Slope Correction Factor * Plot Radius Factor
= 1.0198 * 1.333
= 1.359
= Slope Corrected Plot Radius Factor * DBH
= 1.359 * 20.9 = 28.4 feet

5. Measure the distance from plot center to the face of the tree, nearest plot center, at DBH
or DRC. Both the slope measurement and distance measurement must be taken at plot
center. If the measured distance is less than the limiting distance, the tree is “in.”
Figure J-1. Determining limiting distance on a slope.
Example 3:
BAF=
DBH=
Slope=
Slope Distance =
40
15.0
50%
21.0 feet
Referring to Table K-6, the Combined Factor for a slope of 50% with a 40 BAF is 1.490.
Limiting distance
= DBH * Combined Factor
= 15.0 * 1.490
= 22.35
Since 21.0 is less than or equal to the limiting distance of 22.35 feet, the tree is “in” and
is tallied as a sample tree.
Measuring “In” or “Out” Down Trees
Down trees are “in or out” of the variable plot radius based on where the DBH or DRC now
lies, not on where the tree once stood. The distance measurement is taken from plot center
to the nearest face of the tree at breast height.

Table J-6: Limiting Distance to Face of Tree and Slope Correction Factors for Various Basal
Area Factors
This table provides an expanded list of slope correction factors to the face of the tree for use with various
basal area factors. To use the table, measure the slope and the distance from plot-center to the face of the
tree at DBH. To obtain the corrected limiting distance to a tree multiply the trees DBH by the “combined
factor” shown under the appropriate BAF heading.

Definition
A position facing or commanding a given direction; exposure. Aspect is the
compass direction of the prevailing slope with respect to true north.
A horizontal angular measure from true north to an object of interest.
The cross-sectional area of the stem or stems of a plant or of all plants in a stand,
generally expressed as square units per unit area. For trees, measured at 4.5 feet
above ground, for forbs and grasses, measured at the root crown.
The straight-line distance measured parallel to the main bole of a tree, from its
base to its tip.
A point located on the uphill side of the main stem, by measuring 4.5 feet along
the uphill side of the bole from ground level or the predominant root collar.
Preclude slight, non-compacted litter accumulations when establishing breast
height.
Classification and Assessment with LANDSAT of Visible Ecological Groupings. It
is a California-wide system for classifying vegetative and non-vegetative cover
types. The primary cover type relates to life form and uses a 3-character alpha
code.
The percent of a fixed area covered by the crown of an individual plant species
or delimited by the vertical projection of its outermost perimeter; small
openings in the crown are included.
The percent of the total height of the tree that supports a full, live crown. For
trees that have uneven length crowns, occularly transfer lower branches to fill
holes in the upper portions of the crown, until a full, even crown is created.
A land area, usually between 3,000 and 8,000 acres, easily identified on the
ground by physical features. A compartment is comparable in size to a subwatershed, or landscape management unit. It is used as a convenience for
maintaining stand records and planning vegetation management projects.
The relative position of the tree or shrub crown with respect to the competing
vegetation around it. Crown class for each tree or shrub is judged in the context
of its immediate environment, that its, those trees or shrubs which are
competing for sunlight with the subject tree or shrub.
The vertical distance from the top of the leader to the base of the crown,
measured to the lowest live branch-whorl with live branches in at least 3
quadrants, and continuous with the main crown.
The ratio of compacted live crown length to bole length. Lengths are measured
parallel to the bole from the base of the tree to the tip.
Digital Elevation Model. USGS geographic elevation data distributed in raster
form. Digital representation of the shape of the earth's surface. Typically, digital
elevation data consists of arrays of values that represent topographic elevations
measured at equal intervals on the Earth's surface.
The length of a straight-line segment passing through the center of an item and
terminating at its periphery.
A measure at breast height (4.5 feet), outside bark, of the tree bole,
perpendicular to the tree bole.
The straight line passing through the center of a cross section of a bole measured
at the root collar of a shrub or tree.
Stem material (conifer or hardwood) that is lying on the ground. If a stem
material is leaning more than 45 degrees from vertical, is not self-supporting,
and/or in contact with the ground, it is considered a down log.

Definition
Woody pieces of trees and shrubs that have been uprooted (no longer
supporting growth) or severed from their root system, not self-supporting, and
are lying on the ground.
Duff is the fermentation and humus layer of the forest floor. It does not include
the freshly cast material in the litter layer. The top of the duff is where needles,
leaves, and other cast-off vegetative material have noticeably begun to
decompose. Individual particles usually will be bound by fungi mycelium. When
moss is present, the top of the duff is just below the green portion of the moss.
The bottom of the duff is the start of the soil (“A” horizon).
Vertical distance from a datum, usually mean sea level, to a point or object on the
earth’s surface. Not to be confused with altitude, which refers to points above
the earth’s surface.
The fuel bed is the accumulation of dead, woody residue on the forest floor. It
begins at the top of the duff layer and above. It includes litter, dead limbwood
and bolewood from tree species, as well as dead material from shrub,
herbaceous, and grass species.
Mathematical descriptions of fuel properties (e.g., fuel load and fuel depth) that
are used as inputs to calculations of fire danger indices and fire behavior
potential.
Global Positioning System. A network of radio-emitting satellites deployed by
the U.S. Department of Defense. Ground-based GPS receivers can automatically
derive accurate surface coordinates for all kinds of GIS, mapping, and surveying
data collection.
The forest floor, made up by soil and duff layer. It does not include
unincorporated woody debris that may rise above the ground line. In reference
to a point of measure, it is the highest point of the ground touching the base of
the object being referenced.
A count of one or more items of the same type or species and recorded as a
single line entry.
A measure of the increase in growth layers for a specified time frame.
The increase in height over a set period of time.
Measurement of diameter at a point where the sampling plane intersects the
geometric center of the object being tallied. No adjustment is made for stem
irregularities at the point of intersection.
The deflection from vertical, > 15 degrees of a straight line passing through the
geometric center of the base and top of the main stem.
The measurement of the extent of something along its greatest dimension.
Species and individuals that are grouped into classes on the basis of their
similarities in structure and function. A growth form that displays an obvious
relationship to important environmental factors.
A comparative measurement between the subplot radius and the distance from
the subplot center to the center of the object. The comparison is used to
determine whether the object is IN or OUT of the fixed area subplot.
IN - The object is “in” if the measured distance is equal to or less than the subplot
radius.
OUT - The object is “out” if the measured distance is greater than the subplot
radius.
The straight-line distance measured parallel to the main bole of a tree, from the
top of the live crown to the base of the live crown.

Definition
The identification of the legal owner/administrator on both the surface and
subsurface estates.
The major subdivision of a genus or subgenus of a plant being described or
measured.
The size and shape of the sampling unit (plot) and the spatial arrangement of
subplots within that unit.
A sub-sample of a plot or stand exam. This is the unit on which data are
recorded to individual trees, snags, logs, understory vegetation, and fuels. Data
can be collected on either a fixed area or variable radius area.
Units of the National Forest System as originally proclaimed or designated by
Congress.
The diameter of the tree of average basal area.
The increase in tree radius over a period of time at breast height, or occasionally
at the base.
Any method of sample selection based on the theory of probability (degree of
certainty). At any stage of the operation of selection, the probability of any set of
units being selected must be known. It is the only method that can provide a
measure of precision of the estimate.
A code used to reflect the status of an individually tallied item with regards to
previous surveys.
A deviation from the horizontal.
A code that represents a fundamental category of taxonomic classification of an
organism.
A spatially continuous group of trees and associated vegetation having similar
structures and growing under similar soil and climatic conditions.
Basic data collection method for stand exams. It consists of a set of plots,
separated by equal distances on a grid pattern. The lines of the grid (transects)
are oriented in cardinal directions. There is a predetermined distance between
plots. The number of transects and grid plots will vary depending upon the size
and shape of the stand.
A method of sampling forest resources where stands or polygons of similar
properties are lumped into strata. This improves the efficiency of an inventory
by reducing the variability within a given population. The less variability there
is within a strata, the fewer samples will need to be taken to achieve a
statistically valid result.
A group of stands within a condition class; similar characteristics such as forest
type, tree size class, and canopy density.
The woody base of a tree remaining in contact with the soil after the trunk or
main stem has been severed at a point less than 4.5 feet above ground height
(measured on the uphill side).
A woody perennial plant, typically large, with a single well-defined stem carrying
a more or less definite crown.
Total age of the above ground stem of a tree (not age of the root stock or the total
age from seed). Total age is usually the annual ring count to the pith of the tree
at breast height plus an estimate of the number of years it took the tree to reach
breast height.

Contains fine, very porous, and continuous herbaceous fuels that have cured or are nearly cured.
Generally less than one-third of the area contains shrubs or timber. Grasslands and savanna are
represented along with stubble, grass-tundra, and grass-shrub combinations. A nnual and perennial grasses
are included in this fuel model.
Herbaceous material with litter and dead-down stem wood from the open shrub or timber overstory. Open
shrub lands and pine stands or scrub oak stands that cover one-third to two-thirds of the area. Stand may
include clumps and may include pinyon-juniper
Stands are tall, averaging about three feet, but considerable variation may occur. Approximately one-third
or more of the stand is considered dead and cured. May include cultivated grains that have not been
harvested, tall prairie, and marshland grasses.
Stands of mature shrubs, 6 feet or more tall such as California mixed chaparral, the high pocosin along the
east coast, the pine barrens of New Jersey, or the closed jack pine stands of the north-central states.
Besides flammable foliage, stand may contain dead woody material. May contain a deep litter layer.
Shrubs are young with little dead material, and the foliage contains little volatile material. Usually shrubs
are short and almost totally cover the area. Young, green stands with no dead wood qualify: laurel, vine
maple, alder, or even chaparral, manzanita, or chamise.
The shrubs are older, but not as tall as model 4, nor do they contain as much fuel as model 4. This model
covers a broad range of shrub conditions: intermediate stands of chamise, chaparral, oak brush, low
pocosin, Alaskan spruce taiga, and shrub tundra. May include hardwood slash that has cured. Pinyonjuniper shrub lands may be represented.
Stands of shrubs are generally between 2 and 6 feet high. Palmetto-galliberry understory, with a pine
overstory, are typical. Low pocosin may be represented. Black spruce shrub combinations in Alaska may
also be represented.
Contains closed canopy stands of short needle conifers or hardwoods that have leafed out. The compact
litter layer is mainly needles, leaves, and occasionally twigs because little undergrowth is present.
Representative conifer types are white pine, lodgepole pine, spruce, fir, and larch.
Both long-needle conifer stands and hardwood stands, especially the oak-hickory types, are typical.
Closed stands of long-needled pine like ponderosa, Jeffrey, red pines, or southern pine plantations are
grouped in this model. May contain concentrations of dead-down woody material.

Dead-down fuels include quantities of 3-inch or larger limb wood resulting from over maturity or natural
events that create a large load of dead material on the forest floor. Any forest type may be considered if
heavy down material is present; examples are insect- or disease-ridden stands, wind thrown stands,
overmature situations with deadfall, and aged light thinning or partial cut slash.
Contains slash and herbaceous material intermixed with slash. Light partial cuts or thinning operations in
mixed conifer stands, hardwood stands, and southern pine harvests are considered. Clearcuts generally
produce more slash than represented here. The less than 3-inch material load is less than 12 tons per acre.
The greater than 3 inch is represented by not more than 10 pieces, 4 inches in diameter, along a 50 foot
transect
The visual impression is dominated by slash and much of it is less than 3 inches in diameter. The fuels
are well distributed. Heavily thinned conifer stands; clearcuts, and medium or heavy partial cuts are
represented. The material larger than 3 inches is represented by encountering 11 pieces, 6 inches in
diameter along a 50 foot transect
There is a continuous layer of slash. Large quantities of material larger than 3 inches are present.
Clearcuts and heavy partial cuts in mature and over mature stands are depicted where the slash load is
dominated by the greater than 3 inch diameter material. Fuels less than 3 inches are generally only 10
percent of the total load. May include situations where the slash still has “red” needles attached.
Land covered by urban and suburban development. The area must not support wildland fire spread. In
some cases the area may experience structural fire losses during a wildland fire incident; however,
structure ignition in those cases is either house-to-house or by firebrands, neither of which is directly
modeled using fire behavior fuel models. If sufficient vegetation surrounds structures such that wildland
fire spread is possible, then choose a fuel model appropriate for the wildland vegetation.
Land covered by permanent snow and ice. Areas covered by seasonal snow and ice can be mapped to two
different fuels models.
Agricultural land maintained in a nonburnable condition; examples include irrigated annual crops, mowed
or tilled orchards, and so forth. However, there are many agricultural areas that are not kept in a non
burnable condition. For example, grass is often allowed to grow beneath vines or orchard trees, and wheat
or similar crops are allowed to cure before harvest; in those cases use a different fuel model.
Land covered by open bodies of water such as lakes, rivers and oceans.
Land devoid of enough fuel to support wildland fire spread. Such areas include gravel pits, arid deserts
with little vegetation, sand dunes, rock outcroppings, beaches and so forth.
The primary carrier of fire is sparse grass, though small amounts of fine fuel may be present. The grass is
generally short, either naturally or by grazing, and may be sparse or discontinuous. The moisture
extraction is indicative of a dry climate fuelbed, but may also be applied in high-extinction moisture
fuelbeds because in both cases predicted spread rate and flame length are low compare to other grass
models.

feet.
The primary carrier of fire is continuous humid-climate grass. Load is greater than 105 but depth is about
the same. Grass is less coarse than 105.
The primary carrier of fire is continuous dry-climate grass. Load and depth are greater than 104. Grass is
about 3 feet tall.
The primary carrier of fire is continuous, very coarse, humid-climate grass. Load and depth are greater
than 106. Spread rate and flame length can be extreme if grass is fully cured.
