Appendix I: Fixed Radius Plot
APPENDIX I: FIXED RADIUS PLOT
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:

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 sub-watershed, 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.

Definition
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 selfsupporting, and/or in contact with the ground, it is considered a down
log.
Woody pieces of trees and shrubs that have been uprooted (no longer
supporting growth) or severed from their root system, not selfsupporting, 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.

Definition
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.
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.

Definition
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.

Detailed Description
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.
Annual 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. Pinyon-juniper 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 deaddown woody material.

Detailed Description
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.
The primary carrier of fire is grass, though small amounts of fine dead fuel may be present.
Load is greater than 101, and fuelbed may be more continuous. Shrubs, if present, do not
affect fire behavior.
The primary carrier of fire is continuous, coarse, humid-climate grass. Grass and herb fuel
load is relatively light; fuelbed depth is about 2 feet. Shrubs are not present in significant
quantity to affect fire behavior.
