	 This report presents a summary of the most recent inventory information for Wyoming’s forest lands. The report

includes descriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, removals,

and net change. Most of the tables are organized by forest type, species, diameter class, or owner group. The

reort also describes inventory design, inventory terminology, and data reliability.

	 Results show that about 18 percent, or 11.4 million acres, of the total land area of Wyoming is forest land. Fiftythree percent of the forest land is administered by the USDA Forest Service. About 33 percent of the forest land

in Wyoming is in reserved status. Lodgepole pine and spruce-fir forest types combined account for 40 percent of 

total forest land. Lodgepole pine totals 1.2 billion trees or 27 percent of all live trees on forest land. Gross annual

growth of all trees on forest land totaled 331 million cubic feet. Annual mortality of all trees on forest land totaled

172 million cubic feet.

Introduction ____________________________________________________

This report presents a summary of the most recent inventory data available for 

Wyoming’s forest lands. The purpose of this report is to summarize how much forest 

exists, where it exists, who owns it, how it may be changing, and how trees are growing compared to those that are dying in the State of Wyoming. Species composition, 

stand structure, and age of the forests are presented. State-wide population estimates 

of numbers of trees, inventory volume, inventory biomass, and various categories of 

these estimates are also presented. Estimates of tree growth, mortality, and removals 

are discussed in relation to forest health and timber supply assessments. Two sections 

address the forest resources in Yellowstone National Park and in areas designated as 

roadless. The information is presented in text, map products, and graphics.

The data reported here are results of inventories conducted by the USDA Forest 

Service, Interior West Forest Inventory and Analysis (IW-FIA) Program of the Rocky 

Mountain Research Station, as part of their national FIA activities. Forest Inventory 

and Analysis (FIA) is a national program that conducts strategic-level inventories for 

large-scale planning and monitoring. The IW-FIA is one of five regional FIA programs, 

and conducts inventories in eight States in the Interior West.

The plot design, sampling intensity, and grid layout used in the most recent inventory 

of Wyoming are nationally consistent, probability based, and sample all ownerships. 

The design of the field plot, where field crews take the measurements that generate the 

estimates in this report, is referred to as the mapped-plot design and is explained in the 

“Methods” section. The sampling protocol used in the Wyoming inventory, which was 

conducted between 1998 and 2003, differed from protocol used in earlier inventories. 

Caution should be used in comparing numbers in this report with forest statistics previously reported for Wyoming (Green and Conner 1989). Reserved lands and National 

Forest System lands were not inventoried by FIA in the 1989 inventory; they were 

inventoried by National Forest Systems. Additionally, definitions and classifications 

have been refined over time as FIA moves forward as a national program that samples 

consistently across regional boundaries.

This information can be used in many ways, such as assessing the sustainability of 

ecosystem management practices, supporting planning and decisionmaking activities 

undertaken by public and private enterprises, and evaluating habitat conditions. Key 

program customers include State and National Forest policy lawmakers, State foresters, forest industry consultants, environmental organizations, Forest Service officials, 

researchers, journalists, and interested private citizens.

It is beyond the scope of a State-level assessment to do a detailed analysis of small 

domains or address all pertinent natural resources issues. However, there are a variety 

of ways that a user can obtain more detailed analysis and data for Wyoming. Since the 

National Forest System controls over 50 percent of the forest area in Wyoming, with 

six different National Forests spanning two regions, additional information is available. A set of tables, similar to the set in this report, can be generated for each National 

Forest and supplied to an interested user. Eventually, a brochure will be published that 
 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

provides a detailed summary of forest conditions for each National Forest in Wyoming. 

A detailed analysis of Wyoming’s forest products industry has been published by Morgan and others, 2005. A Web-based data compilation and analysis engine—the Forest 

Inventory and Analysis Database—is available to the public and allows users to access 

data and results in a consistent manner for Wyoming and any other State in the country. 

A highly trained, professional IW-FIA staff, located in Ogden, Utah, is also available 

to answer questions, provide data, collaborate with the public, and do special analysis 

upon request.

Wyoming’s forest inventory is a broad-scale survey that provides statistically reliable estimates of forest conditions including forest area, inventory volume, growth, and 

mortality for large geographic areas. Users are cautioned about making assumptions for 

small geographic areas using FIA inventory statistics.

Land classification categories are individually defined in the “Terminology” section 

of this report. However, an overview of the classification relationships may provide a 

better understanding of how these groups are subdivided. Land area is divided into forest and nonforest land (fig. 1). Forest land is subdivided into reserved and nonreserved 

status and then subdivided into timberland and woodland. Nonreserved forest land is 

considered available for harvesting activity where wood volume is available to be used 

for timber products. Reserved forest land is withdrawn from management of timber 

products through statute or administrative designation.

Timberland includes forests of tree species traditionally used in the forest products 

industry, such as ponderosa pine and Douglas-fir. Woodland includes tree species such 

as pinyon, juniper, and oak that are not traditionally used for industrial wood products 

and typically have a multistem growth form. A map illustrating the spatial distribution 

of timberland, woodland, and nonforest land in Wyoming is found in figure 2. Each inventory location was classified as timberland or woodland depending on which category 

of species made up the majority of the stocking. Nonforest land includes rangelands, 

agriculture, urban lands, and water, and may have a small amount of tree cover.

This report and the included tables were developed based on historical demand and 

on recent requests from users including private landowners, agency and university 

researchers, forest industry officials and consultants, National Forest System managers, State and local planning staffs, and regional and national policymakers. The 1998 

through 2003 inventory was made possible through a major cooperative effort between 

Federal and State agencies. Substantial cooperation in terms of logistical assistance was 

received from many other public and private landowners.

Methods _______________________________________________________

The data in this report represent estimates for all forest land, including all owners 

and land status. The FIA inventory procedure for estimates in this report consists of two 

phases. Phase 1 refers to a grid of sample points systematically located across all lands 

on remote sensing imagery. Phase 2 refers to a systematic random sample of field plots 

established across the landscape, sampling all ownerships and status. Field crews visit 

Phase 2 field plots and take detailed measurements that generate inventory estimates 

such as forest cover type, forest inventory volume, forest growth, and forest mortality. 

Each Phase 2 plot is located on a grid across the State and represents approximately 

6,200 acres.

The current periodic inventory of Wyoming forests began in July 1998 and was 

completed in August 2003. A periodic inventory measures all of the Phase 2 plots in 

the State over a period of time, and usually takes several years to complete. Subsequent 

inventories occurred on an average of about 10 years.

The Phase 1 classification in Wyoming used Landsat Thematic Mapper (TM) satellite 

imagery obtained from the National Land Cover Data (NLCD) database. The spatial 

resolution of the imagery was 30 meters and was mapped in the Albers Conic Equal 

Area projection, NAD 83. The Phase 1 sample was a collection of points located on a 

1,000-meter-square grid overlaid on the Wyoming TM image. The State was subdivided 

into a number of stratified sample areas. Within each sample area, Phase 1 points were 

raster-classified into three land status strata (timberland, woodland, and nonforest). The 

area of timberland, woodland, and nonforest land was determined for each sample area 

by incorporating the Phase 1 and Phase 2 observations into a design that used double 

sampling with stratification (Cochran 1963).

The area estimator for timberland in each sample area in Wyoming is defined as:

n′

g = total number of Phase 1 points in sampling area g

yihg = condition proportion on plot i in stratum h in sampling area g

nhg = number of plots in stratum h in sampling area g

The field plot used in Phase 2 is the mapped-plot design (USDA Forest Service, 

1999), which consists of four fixed-radius subplots. Each 1/24-acre circular subplot 

samples trees 5.0 inches in diameter. A 1/300-acre circular microplot located within the 

subplot samples seedlings and saplings (trees up to 4.9 inches in diameter). The sampling protocols are essentially those presented in Scott and Bechtold (1995). One of the 

variables recorded for each plot is the proportion of plot area in each condition class. A 

condition class is defined as the combination of variables that identify different stand 

characteristics. In Wyoming, five attributes were used to determine if different conditions 

existed: land status (forest-nonforest), forest type, stand size, stand origin, and stand 

density. When the field crew determined a distinct difference in stand conditions on a 
USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 

subplot, the boundaries between conditions were mapped and trees were assigned to 

the appropriate condition class. All attributes measured on each location were assigned 

to their respective condition class. Of the 9,956 Phase 2 plots in Wyoming, 1,981 plots 

sampled forest land.

The FIA inventories provide a probability-based sample of forest resources across 

all ownerships that can be used for planning and analyses at local, State, regional, and 

national levels. The sample is designed to meet national standards for precision in State 

and regional estimates of forest attributes.

A measure of the variability of inventory statistics is provided by standard errors, 

listed in table 2, for estimates of area, volume, growth, and mortality on forest land for 

the entire State. These data indicate a sampling error of ± 1.30 percent for the estimate 

of total forest land, 2.32 percent for total net volume of live trees, and 9.74 percent for 

net annual growth of all live trees. As the totals are broken down by forest type, species, tree diameter, or other subdivisions, the sampling error increases. A 95 percent 

confidence interval can be computed for any estimate by multiplying the estimate’s 

percent standard error (SE) by 1.96, multiplying that product times the estimate, and 

then adding and subtracting that product from the estimate to get the bounds. The 95 

percent confidence interval for total forest land area in Wyoming is between 11.1 and 

11.7 million acres. Similarly, the estimate of total forest land volume ranges between 

18.9 and 20.7 billion cubic feet.

Users may compute statistical confidence for subdivisions of the reported data using 

the formula below. Because sampling error increases as the area or volume considered 

decreases, users should aggregate data categories as much as possible. Sampling errors 

obtained from this method are only approximations of reliability because homogeneity 

of variances is assumed. The formula is:

 SẼg = SE Y

where:

SẼg = approximate percent standard error of ˆ

Yg

SEt = percent standard error of ˆYt

ˆY = table variable of interest

g = table cell or group of cells of interest

t = totals from tables 2 or 3

Overview of Tables______________________________________________

Area of forest land, number of trees, wood volume and biomass, growth, mortality, 

and removals are the primary categories for which statistics are summarized and presented in the tables. There are five groups of tables. Tables 1 through 27 are for all forest 

land, both reserved and nonreserved. Tables 28 through 43 are for nonreserved forest 

land—forest land not withdrawn from tree utilization through statute or administrative 

designation. Tables 44 through 81 are for nonreserved timberland, that is nonreserved 

forest land that is 10 percent stocked and where timber species—those species traditionally used for industrial wood products—comprise more than half of the total stocking 

on the site. Tables 82 through 89 are for nonreserved woodland, meaning forest land 

where timber species make up less than half of the total stocking. The last group of 

tables, 90 through 111, is a set of tables comparable to similar sets presented by other 
 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

FIA groups across the nation and used in the Resources Planning Act Assessment to 

represent lands traditionally referred to as productive timberland. These “Core” tables 

are primarily for nonreserved timberland that has a minimum productivity of 20 cubic 

feet per acre per year.

Map Products___________________________________________________

This report contains a number of map-based figures that were generated using ArcGIS software. Some of the maps used modeling techniques to produce the coverage. 

For example, figure 8 illustrates a map displaying coverage of the major forest types in 

Wyoming. The modeled coverage in this map was generated by the Cubist procedure 

(Quinlan 1993) —a rule-based predictive model that estimates forest attributes. The forest 

type classification at each forested sample location was used to train the model in relation to the various predictor variables extracted from over 50 data layers. Approximately 

half of these data layers were 2002 Moderate-resolution Imaging Spectrordadiometer 

(MODIS) scenes and the other half were ancillary GIS data layers. By using MODIS 

imagery and the Cubist modeling procedure, the resulting maps can be produced in a 

timely and attractive manner that contains a statistical measure of accuracy. Adding map 

layers such as shaded relief or digital elevation models enables the reader to compare 

the relationship of topographic features to forest type.

All map-based products that appear in this report have estimates of reliability, and 

have undergone an evaluation process to assess accuracy and identify potential for 

misinterpretation. This process may be referred to as predictive performance, which 

consist of visual and statistical evaluations.

Low estimates of accuracy and low correlation coefficients can be attributed to differences in scale, date inconsistencies, and problems with certain site-specific information. These map-based products should be used with caution especially when evaluating 

relatively small geographic areas (predictor layers were based on a 250-meter pixel for 

these models). Invariably, users of these products will attempt to draw conclusions for 

small domains. Not all FIA response variables yield the same prediction performance 

when using the same model.

Highlights of Inventory Results For Total Forest Land _______________

Area

The State of Wyoming encompasses over 62 million acres of land area (table 1). The 

forested areas of Wyoming located in the western and central portions of the State are 

part of two provinces referred to as the Southern Rocky Mountain Steppe and Middle 

Rocky Mountain Steppe (Bailey 1978). The Rocky Mountains are rugged glaciated 

mountains as high as 14,000 feet with local relief between 3,000 feet and 7,000 feet. 

Most of the forest land in Wyoming is concentrated in the northwest region of the State 

(fig. 2). An isolated area of forest land exists in the northeast area of the State where 

ponderosa pine forests have found an ecological niche in the higher elevations of the 

plains and foothills of the Black Hills. This province is referred to as the Black Hills 

Coniferous Forest Province (Bailey 1978).

Approximately 18 percent of the land area, or about 11 million acres, is classified as 

forest land (fig. 3). Fifty-three percent of the forest land is administered by the USDA 

Forest Service, and 17 percent is privately-owned, which includes Indian Trust land 

(fig. 4). Fifteen percent is administered by the National Park Service, 11 percent is 

administered by the USDI Bureau of Land Management (BLM), and the remaining 4 

percent is owned by State, county, and miscellaneous Federal agencies. About one-third

of the total forest area is in a reserved status. Figure 5 spatially illustrates the location 

of the major owner groups on forest land in Wyoming.

The area variables discussed below describe the structure and composition of Wyoming’s forests. Some of the variables were originally developed to describe forests in 

terms of growing-stock and timber production and have been adapted for use in describing all trees on all forest land.

USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 

Forest type—Forest type refers to the predominant tree species in a stand based 

on tree stocking, and is considered an indicator of forest diversity. The lodgepole pine 

type is the most abundant forest type in Wyoming, covering over 2.6 million acres, or 

23 percent of forest land (table 3). Second in abundance, the spruce-fir type covers 1.8 

million acres or 16 percent of the State’s forest land. Third, ponderosa pine totals 1.1 

million acres and accounts for 9 percent of forest area. Douglas-fir and Engelmann spruce 

each make up 8 percent of the area; juniper, 8 percent; aspen, 6 percent; whitebark pine 

5 percent, and limber pine 4 percent. Nonstocked forest land accounts for 10 percent of 

total forest land. Nonstocked forest land includes sparsely stocked woodland, recently 

cut and burned areas, and other areas that fall below a 10-percent stocking threshold 

of live trees. Figures 6 and 7 illustrate the distribution of forest type on timberland and 

woodland. Lodgepole pine predominates on timberland, whereas juniper is the most 

abundant forest type on woodland.

Figure 8 is a map displaying the major forest types and forest type groups overlayed 

with a shaded relief map layer in Wyoming. This display illustrates the very evident and 

somewhat predictable nature of vegetation zones in relation to mountainous topographic 

features. Vegetational zonation in the Southern Rocky Mountain Steppe is controlled by 

a combination of elevation, latitude, direction of prevailing winds, and slope exposure. 

The uppermost (alpine) zone is characterized by alpine tundra and the absence of trees. 

Directly below is the subalpine zone dominated by Engelmann spruce and subalpine fir.

Figure 7—Area of woodland by forest type, Wyoming, 2002.

Below this area lies the montane zone, characterized by ponderosa pine and Douglas-fir, 

depending on aspect. Ponderosa pine favors drier, exposed slopes, whereas Douglas-fir 

prefers the higher, moist, sheltered areas. Below the montane zone is the foothill zone 

where mountain-mahogany and several species of oak are present. Lodgepole pine is 

heavily concentrated in the northwest region where Yellowstone National Park is located. 

This area is part of the Middle Rocky Mountain province characterized by basins and 

ranges. The spruce-fir types indicate an elliptical pattern surrounding the harsh, exposed 

environment of the alpine zone. Douglas-fir follows the east-facing coves at the higher 

elevations. Ponderosa pine is heavily concentrated in the northeast region where the 

Black Hills National Forest is located.

Stand size—Stand size is a classification of forest land based on the predominant 

diameter class of live trees presently forming the majority of live tree stocking (tables 4 

through 7). The names of two of the four stand-size classes (sawtimber and poletimber) 

are often misinterpreted by readers of FIA reports. Sawtimber and poletimber refer 

only to a tree-size category and do not imply a commercial species classification. Both 

timberland and woodland tree species can fall into the sawtimber and poletimber standsize class. Figure 9 illustrates area of forest land by stand-size class. The majority of 

stands (56 percent) are comprised of large-diameter trees (sawtimber stand-size class). 

Eighteen percent of forest stands are composed of small trees (sapling/seedling standsize class), such as newly regenerated areas following harvesting activity or fire. The 

distribution of forest land by stand-size class varies significantly between timberland

and woodland (fig. 10). The proportion of sawtimber and nonstocked stand-size classes 

is higher on land classified as woodland as opposed to timberland.

Stand age—Figure 11 illustrates area of forest land by stand-age class. Like stand 

size, age is an indicator of forest structure, but difficult to quantify in stands comprised 

of trees of many different ages. Therefore, interpretation of stand-age statistics should 

be used with caution especially when making certain assumptions such as old-growth 

conditions. Stand age is a computed variable using only those ages of trees within the 

computed stand-size class and weighted by trees per acre. If a computed stand-size class 

is nonstocked, the age class is defined as unclassified. Ninety-one percent of all forest 

stands in Wyoming are estimated to be less than 200 years old and less than 1 percent 

is over 300 years old. Figure 12 illustrates how stand-age class distribution differs between timberland and woodland. Figure 13 spatially depicts stand age distribution on 

forest land in Wyoming. Note the prevalence of stands in the youngest age class in the 

northwest region of the State. Many of these stands are young lodgepole pine forests 

that regenerated after the large-scale fires that occurred in 1988.

Basal area class—Basal area (BA) is the cross-sectional area of a tree stem associated with a diameter measured at a specified point on the stem, expressed in square feet. 

Basal area of a forest stand is the sum of the basal areas of all individual live trees in the

stand and is often used to measure site occupancy. Figure 14 illustrates area of forest 

land by basal-area class, and indicates that more than half (52 percent) of forest land in 

Wyoming is in stands with basal areas of live trees greater than 75 square feet per acre. 

Mean basal area of live trees averages 91 square feet per acre on all forest land. Mean 

basal area of live trees on timberland is 93 square feet per acre on timberland and 67 

square feet per acre on woodland. Stands with a high level of basal area are often in a 

state of competition where the trees are stressed and highly susceptible to invasion by 

disease and insects. Eventually, many trees die and accumulations of standing dead and 

down material create a fuel source for fires.

Stand density index—Stand density index (SDI), as developed by Reineke (1933), 

is a relative measure of stand density that quantifies the relationship between trees per 

acre, stand basal area, average stand diameter, and stocking of a forested stand. Western 

silviculturists often use SDI as one measure of stand structure to meet diverse objectives 

such as ecological restoration and wildlife habitat. Originally developed for even-aged 

stands, SDI can also be applied to unevenaged stands (Long and Daniel 1990; Shaw 

2000). SDI is usually presented as a percentage of a maximum SDI for each forest type 

(USDA Forest Service 1991). SDI was computed for each condition that sampled forest 

land using maximums shown in table 12, and the results were grouped into six classes. 

A comparison between the distribution of forest area on timberland and woodland 

by SDI class is illustrated in figure 15. A site is considered to be fully occupied at 35

slowed growth rates. The IW-FIA survey estimates that 35 percent of all forest stands 

in Wyoming are at or above 35 percent of SDI maximum.

Number of Trees

The number and distribution of individual tree species is another indicator of forest 

diversity. Softwood species are predominate, with lodgepole pine being the single most 

abundant species on forest land in Wyoming. Lodgepole pine totals 1.2 billion trees, or 

27 percent of all live trees on forest land. Second in abundance is subalpine fir, which 

accounts for 25 percent of all live trees on forest land, and Engelmann spruce is third 

at 11 percent.

Lodgepole pine also predominates on forest land that is classified as timberland, followed by subalpine fir and Engelmann spruce. Together, these three species account for 

two-thirds of all live trees on timberland (fig. 16). The number of live trees on forest 

land that is classified as woodland totals 232 million trees. Rocky Mountain juniper is 

the single most abundant species occurring on woodland in Wyoming and accounts for 

45 percent of the woodland total (fig. 17). Second in abundance is Utah juniper, which 

totals 72 million trees or 31 percent of the woodland total. Other species recorded on 

woodland include Rocky Mountain maple, curleaf mountain-mahogany, and ponderosa 

pine.

Figure 18 illustrates the distribution of numbers of live trees on timberland and 

woodland by diameter class (includes d.b.h. and d.r.c.). Sixty-one percent of all live 

trees on forest land are less than 5 inches in diameter. Less than one percent of all live 

trees are larger than 22 inches in diameter.

Dead trees, often referred to as snags, are a significant component of forest ecosystems, 

contributing to habitat for many species of wildlife and soil nutrients. Snags also play 

an important role in fire-related analysis because of their contribution to fuel sources. 

The most recent inventory of Wyoming forests recorded slightly less than 1 billion 

standing dead trees, and 45 percent were greater than 5.0 inches in diameter. Lodgepole 

pine accounted for the majority (39 percent) of standing dead trees in Wyoming and 

subalpine fir was second in abundance (21 percent). The mean number of standing dead 

trees 5.0 inches in diameter and larger averages 38 trees per acre on forest land, 42 on 

timberland, and 9 on woodland. These averages represent total forest land area and do 

not account for the uneven distribution of standing dead trees caused by fire, disease, 

and insect outbreaks. For example, there are significant numbers of standing dead trees 

in Yellowstone National Park as a result of the large scale fires that occurred in 1988. 

The average number of standing dead trees 5.0 inches in diameter and larger on National 

Park land in Wyoming is nearly 89 trees per acre.

Biomass and Volume

The total oven-dry biomass of all live trees in Wyoming is 350 million tons. Biomass 

includes boles, bark, and branches of all live trees. Biomass on timberland totals 345 

million tons (fig. 19) and 5 million tons on woodland (fig. 20 ). Lodgepole pine accounts 

for 30 percent (105 million tons) of the biomass total in the State. Figure 21 spatially 

displays oven-dry biomass of live trees in Wyoming.

Net volume of wood in live trees 5.0 inches in diameter and larger in Wyoming totals 

19.8 billion cubic feet. Softwoods account for 96 percent of this total volume. Lodgepole 

pine, Engelmann spruce, and subalpine fir collectively account for 70 percent of the 

total softwood volume in the State. Aspen accounts for the majority (73 percent) of the 

hardwood volume total, and plains cottonwood accounts for 15 percent.

Growth and Mortality

Forest growth, for FIA reporting purposes, is an estimate that provides additional 

information about trends in the population estimate of inventory volume. As time passes, 

the total volume of live trees in a region or State increases, decreases, or remains the 

same. These changes can be explained, in part, by examining the dynamics of live tree 

growth, tree mortality, and trees removed by harvesting practices. Forest growth is a 

complex estimate for broad-scale inventories. It is not always easy to measure, it is very 

sensitive to changes in sampling procedures over time, and can be defined in several 

different ways.

For these and related reasons, it is necessary to divide forest growth into component 

parts to arrive at consistent definitions. All estimates of growth and mortality are for 

trees 5.0 inches and larger in diameter at the year of inventory. Live tree growth is determined from increment core measurements and is expressed as an annual average over 

a 10-year period. Survivor growth is the average annual change in volume for trees that 

are alive in the current inventory and were estimated to be equal to or greater than 5.0 

inches in diameter 1 year prior to the current inventory. Ingrowth is the current volume 

of trees that are alive in the current inventory and were estimated to be below 5.0 inches 

in diameter 1 year prior to the current inventory. Mortality is the average annual net 

volume of trees that have died in the 5 years prior to the year of inventory. Removal 

volume is the average annual net volume of trees that were removed from the inventory as the result of harvesting activity. The estimate of Wyoming’s removal volume 

was obtained from a separate study and is explained in the “Nonreserved Timberland” 

section. Gross annual growth is the sum of survivor growth, ingrowth, and mortality. 

Net annual growth is gross annual growth minus annual mortality.

Gross annual growth of all trees on forest land in Wyoming totaled 331 million cubic 

feet. Gross growth of all trees averaged 327 million cubic feet on timberland and 4 million 

cubic feet on woodland (figs. 22 and 23). Annual mortality of all trees on forest land in 

Wyoming averaged 172 million cubic feet. Annual mortality of all trees averaged 171 

million cubic feet on timberland and less than 2 million cubic feet on woodland.

The relationship between mortality and gross growth can be used to assess overall 

forest health. High levels of mortality relative to gross growth often indicate deteriorating 

stand conditions due to stagnation, fire, disease, insects, weather, or a combination of 

factors. This relationship is usually expressed as a percentage of annual mortality that is 

deducted from the annual gross growth estimate. Across all forest land, annual mortality 

reduced gross growth by 52 percent. The amount that annual mortality reduced gross 

annual growth varied significantly by species (figs. 22 and 23). Of those species occurring on timberland, annual mortality of whitebark pine reduced gross annual growth 

by 82 percent followed by subalpine fir at 79 percent. Of those species occurring on 

woodland, annual mortality of ponderosa pine and Douglas-fir reduced gross annual 

growth by 110 percent.

Highlights of Inventory Results for Nonreserved Timberland ________

Area and Volume

Wood products are important to local and regional economies, and the majority of 

these products are obtained from the harvesting activities that occurred on nonreserved 

timberland. Nonreserved forest land is not withdrawn from management for production of wood products through statute or administrative designation, and the timberland 
24 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

classification generally refers to forest land comprised of tree species suitable for timber 

products. Nonreserved timberland in Wyoming totals 57 percent (6.5 million acres) of 

the total forest area. National Forest lands account for 62 percent (4.0 million acres) of 

nonreserved timberland; nonindustrial private lands account for 23 percent, and land 

controlled by other public owners account for the remaining 15 percent of nonreserved 

timberland in the State.

The total volume of growing stock on nonreserved timberland is over 11.5 billion 

cubic feet, with 78 percent occurring on National Forest land. Lodgepole pine comprises 

the greatest percentage (29 percent) of growing-stock volume on nonreserved timberland. The volume of sawtimber on nonreserved timberland totals 37.3 billion board feet 

(Scribner rule), with 80 percent occurring on National Forest land. Engelmann spruce 

comprises the greatest percentage (26 percent, or 9.6 billion board feet) of sawtimber 

volume on nonreserved timberland. Second in abundance, lodgepole pine comprises 

23 percent (8.5 billion board feet) of the sawtimber total.

The evaluation of growing-stock volume on a per-acre basis minimizes the effect of 

differences in the amount of area by ownership class. Across all ownerships, the average net volume per acre on nonreserved timberland is 1,780 cubic feet, and 2,251 cubic 

feet per acre on National Forest Systems land. In contrast, net volume per acre on other 

public and nonindustrial private land averages 999 and 1,044 cubic feet, respectively 

(fig. 24). Sawtimber volume on National Forest land averages 7,442 board feet per 

acre compared to 2,681 and 3,220 board feet per acre on other public and nonindustrial 

private land, respectively (fig. 25). Figure 26 spatially illustrates net cubic foot volume 

per acre of growing-stock trees on forest land in Wyoming.

Removals for Timber Products

The net volume of growing-stock trees removed from the inventory by harvesting, 

cultural operations, land clearing, and changes in land use, is known as removals. This 

section deals with removals for timber products. These removals include both the volume processed in mills and the volume harvested or killed but not used. Removals, as 

reported here, are based on data from 1 year (2000). More details about Wyoming’s 

primary forest products industry can be found in Morgan and others (2005). Tables 79 

through 81 show harvest and removals by product, species, and ownership group in cubic 

feet for growing stock removals as well as board feet—Scribner and International—for 

sawtimber removals.

About 15.4 million cubic feet of wood, exclusive of land clearing volume and changes 

in land use, were removed from growing stock on Wyoming’s nonreserved timberland 

in 2000. Ninety-four percent of the volume was used for wood products, less than 1 

percent was used for industrial fuelwood, and 6 percent was left in the woods as logging residues. Sawlogs were the largest component of removals from growing stock, 

followed by posts, poles, and pilings.

National Forests supplied 19 percent of the volume removed from growing stock, 

other public landowners, including the Bureau of Land Management and the State of 

Wyoming, provided about 7 percent, and private landowners supplied the majority (74 

percent) (fig. 27).

Removals of sawtimber-size trees, or sawtimber removals, included 66.7 million board 

feet (Scribner log rule) or 74.7 million board feet expressed in International 1⁄4-inch log

rule. Logs harvested to produce lumber (sawlogs) dominated products harvested from 

sawtimber, accounting for 95 percent of removals. Logging residues accounted for 1.5 

percent of sawtimber removals.

Ponderosa pine was the dominant species harvested, accounting for 62 percent of 

growing stock removals and 67 percent of sawtimber removals. Lodgepole pine accounted for 25 percent of growing stock removals and 21 percent of sawtimber removals. Douglas-fir, spruces, and true firs accounted for nearly all of the volume of the 

remaining removals.

Components of Change

Net annual growth is defined as gross annual growth volume minus average annual 

mortality volume. Net change is defined as net annual growth volume minus the average 

annual volume removed due to harvesting activity (removals). Positive net change usually indicates an increasing inventory over time whereas negative net change indicates 

a declining inventory. Figure 28 illustrates the relationship of net growth of growing 

stock to annual removals for select species groups on nonreserved timberland. Note 

that the net growth estimate is an annual average based on 10 years for gross annual 

growth and 5 years for annual mortality, whereas the removals data were collected over 

a 1-year period. All of the listed species groups indicate that the estimated average an-

nual net growth exceeded the amount of wood volume removed for 1 year (fig. 28). 

When all of the listed species are combined, net growth of growing stock exceeded the 

growing stock removal estimate by a ratio of 8 to 1. The narrowest margin of growth 

to removals was indicated by ponderosa pine, where net growth exceeded removals by 

a margin of 2 to 1.

Wyoming, along with Idaho and Montana, is part of the Northern Rockies. The 

Northern Rockies is regarded as containing the largest resource for supplying timber 

products to the wood-using industry in the Interior West. Timber processing capacity 

is the volume of timber that could be used by existing timber processors if demand for 

products is firm and sufficient raw material is available. Timber processing capacity for 

the Northern Rockies has steadily declined over the past 2 decades, largely because of 

their dependence on National Forest timber. Historically, Federally owned timberland 

in Wyoming supplied the majority of growing-stock removals for the State. Now, National Forests only supply 19 percent of the growing-stock removals, yet they control 63 

percent of the nonreserved timberland in Wyoming. The restricted timber availability on 

Wyoming’s National Forests is the result of numerous constraints, such as appeals and 

litigation of timber sales, threatened and endangered species protection, and impacts of 

past harvesting practices on other natural resources, such as water quality and wildlife. 

The current relationship of growing-stock net growth to growing-stock removals on 

Wyoming’s nonreserved timberland suggests an adequate supply of inventory volume 

that will increase for the foreseeable future.
USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 29

Highlights of Inventory Results for Reserved Forest Land____________

Reserved lands are withdrawn from management for production of wood products 

through statute or administrative designation. Unlike nonreserved timberland, reserved 

forest land is usually set aside legislatively for preservation purposes, such as Yellowstone National Park. Reserved forest land totals 3.8 million acres in Wyoming. Nearly 

all of reserved forest land is classified as timberland. Fifty-two percent of reserved forest 

land is administered by National Forests and 46 percent is administered by National 

Parks (fig. 29).

Lodgepole pine is the predominant forest type on reserved forest land (1.4 million 

acres) (fig. 30). Next in abundance is the spruce-fir type (20 percent), followed by Engelmann spruce at 14 percent of reserved forest land. Whitebark pine accounts for 10 

percent of reserved forest land and nonstocked timberland accounts for 9 percent.

Lodgepole pine is the predominant species in terms of biomass and volume on reserved 

forest land (fig. 31). Oven-dry weight of lodgepole pine biomass is 36 percent (47 million tons) of the reserved biomass total. Second in abundance is Engelmann spruce at 

28 percent (37 million tons) of the total. Subalpine fir and whitebark pine account for 

13 and 12 percent, respectively.

Two noteworthy differences between reserved forest land and nonreserved forest 

land occur in the stand age profiles and gross growth/mortality relationships. Reserved 

forest land is more heavily comprised with older forest stands than nonreserved forest 

land (fig. 32). Over 33 percent of reserved forest land resides in stands greater than 

150 years of age compared to only 16 percent of nonreserved forest land. The annual 

estimate of gross growth exceeds the annual estimate of mortality on reserved land 

by 32 percent (fig. 33). In contrast, gross growth exceeds mortality by 143 percent on

nonreserved forest land. These inventory comparisons indicate that, overall, reserved 

forest land is comprised of older, slow-growing forest stands with elevated levels of 

mortality compared to nonreserved forest land. However, significant differences in 

stand structure exist within the forests classified as reserved. The following chapter on 

Yellowstone National Park’s forests, which are a component of reserved forest land, 

illustrate some of these differences.

Yellowstone National Park

In 1872, President Ulysses S. Grant signed a law declaring that the area known as 

Yellowstone would forever be “dedicated and set apart as a public park or pleasuring 

ground for the benefit and enjoyment of the people.” This was the first reservation of 

wild lands for recreational purposes under the direct management of the Federal government. This country’s first national park was considered unique by early explorers for its 

natural beauty, unique geothermal features (such as Old Faithful geyser), and abundant 

wildlife. This section describes inventory results for the area of Yellowstone National 

Park within the State of Wyoming.

The FIA’s estimate of total land area of Yellowstone National Park in Wyoming is 1.9 

million acres, of which 1.6 million acres (84 percent) is forest land. Figure 34 illustrates 

the area and distribution of forest and nonforest land in Yellowstone National Park in 

Wyoming. Nearly all of the forest land in Yellowstone is classified as timberland 

(fig. 35). Juniper, the only recorded woodland forest type, comprises less than 1 percent 

of Yellowstone’s total forest area. Lodgepole pine is the most predominant forest type in 

Yellowstone, covering nearly 60 percent (1 million acres) of Yellowstone’s forest land 

(fig. 36). Spruce-fir is the second most abundant forest type with 258 thousand acres 

(16 percent). Nonstocked timberland accounts for 11 percent of Yellowstone’s forest 

area. Over 36 percent of the forest area is classified as a sapling/seedling stand-size 

class (fig. 37). The majority (35 percent) of forest stands are estimated to be between 0 

and 51 years of age (fig. 38).

Figure 39 displays the distribution of number of live trees on Yellowstone’s forest 

land by species. Lodgepole pine makes up the largest percentage (58 percent) of number of trees; second in abundance is subalpine fir (22 percent), and Engelmann spruce 

comprises 9 percent of the total. Of particular interest is the status of whitebark pine 

in Yellowstone National Park. Whitebark pine seeds are a critically important fall food 

source for the grizzly bear, and whitebark pine is susceptible to significant mortality from 

white pine blister rust, a nonnative fungus that was introduced to North America from 

Europe. The current estimate of whitebark pine in Yellowstone is 32 million trees, or 6 

percent of total live trees. Figure 40 displays plot locations where at least one whitebark 

pine 1.0 inch in diameter or larger was measured, and whether or not there was at least 

one tree present in the overstory.

In the summer of 1988, the driest period in Yellowstone’s history, large-scale fires 

burned over one-third of the park. The fires created a unique forest ecosystem that has 

been extensively studied over the years to evaluate how forests and wildlife recover from 

severe disturbance. The most significant outcome is a skewed age-class distribution toward 

the younger stands that regenerated following the fires (fig. 38). In the 2002 inventory of 

Wyoming, field crews recorded evidence of fire and the year in which it occurred. The 

inventory estimate of forest area in Yellowstone National Park, Wyoming, that burned 

in 1988 is 803,000 acres. Sixty-four percent of this burned area is currently classified 

as a lodgepole pine forest type, and another 19 percent is nonstocked. Spruce-fir types

are sawtimber stands, and 5 percent are poletimber stands. These inventory statistics 

support what many other studies have concluded: despite the extensive fire-related 

mortality of large-diameter trees, especially lodgepole pine, most of these stands appear 

to be adequately stocked with saplings and seedlings that will eventually develop into 

healthy, mature stands.

Roadless Areas

Roadless areas are lands designated by Federal law that generally limits, with some 

exceptions, timber harvest and road construction on National Forests and Grasslands 

across the country. Figure 41 displays those areas currently designated as roadless in 

Wyoming. The FIA’s estimate of roadless areas in Wyoming is 3.1 million acres, and 71 

percent (2.2 million acres) is classified as forest land. The lodgepole pine and spruce/fir 

forest types together comprise 43 percent of roadless area forest land (fig. 42). Douglas-fir 

accounts for 17 percent and aspen accounts for 10 percent of roadless area forest land. 

By stand-age class, sawtimber stands comprise 60 percent of forest land, poletimber 

stands 22 percent, sapling seedling stands 14 percent, and nonstocked stands comprise 

4 percent of forest land in roadless areas (fig. 43). By stand-age class, most (56 percent) 

of the forest area is concentrated in stands between 50 and 151 years old (fig. 44). Less 

than 15 percent of forest area is in stands 1 to 50 years old and 25 percent is in stands 

greater than 150 years old.

The inventory estimate of live trees on forest land in roadless areas in Wyoming is 892 

million trees. Subalpine fir is estimated to make up the highest percentage (32 percent) 

of number of trees. In continuing order of abundance is lodgepole pine (29 percent); 

Engelmann spruce (11 percent); Douglas-fir (9 percent); aspen (6 percent); whitebark 

pine (5 percent); limber pine (3 percent); and ponderosa pine (1 percent) (fig. 45).

The inventory estimate of gross annual growth of all live trees on forest land on 

roadless areas totals 74.2 million cubic feet and annual mortality totals 35.6 million 

cubic feet. Annual mortality reduced gross growth by 48 percent. Figure 46 illustrates 

gross annual growth and annual mortality on roadless areas for the eight most abundant species. The relationships between gross growth and mortality indicate certain 

species are experiencing elevated levels of mortality and subsequent lower net growth. 

Annual mortality reduced gross growth 86 percent for subalpine fir and 80 percent for 

Douglas-fir. In contrast, annual mortality only reduced gross growth by 7 percent for 

ponderosa pine.

In terms of overall stand structure and composition, roadless areas in Wyoming bear 

a strong resemblance to reserved land. Elevated levels of mortality compared to gross 

growth are common to both roadless and reserved forests. The most unique aspect of 

roadless areas is the amount of area that is located in the subalpine zone of the Southern 

Rocky Mountain Steppe. This is evidenced by the significant areas occupied by Engelmann spruce, subalpine fir, and Douglas-fir.

Summary and Conclusions _______________________________________

At first glance, one might assume that Wyoming’s forests are rather homogenous with 

a predominance of softwood species occurring in mostly mountainous terrain. However, 

as indicated by the 2002 inventory findings, significant State-wide variability does exist 

in certain estimates related to species composition and stand structure. Several of the 

map products underscore these differences. Major differences in species composition 

and stand structure occur between timberland and woodland. These differences are 

largely attributable to moisture regimes—woodland typically occurs on very xeric 

sites whereas timberland progresses from drier sites at lower elevations to the moist, 

cool environments at the very highest elevations. Reserved forest land is characterized 

by older, slow-growing forest stands with higher levels of mortality than nonreserved 

forest land.

Barring significant legislative action, nonreserved timberland will most likely continue to produce timber products at a level well below its potential. The management of 

Federally owned timberland is far more complicated than it was decades ago because 

of the diverse demand that today’s public puts on natural resources. Every acre of National Forest timberland that is under consideration for a timber sale is subject to intense 

scrutiny, and any relevant environmental impact must be addressed.

Besides environmental-related restrictions, there are additional restrictions on the 

timber resource on nonreserved timberland. Figure 47 displays the results of a four-step 

screening process applied to the total area of nonreserved timberland in Wyoming. The

purpose of the display is to demonstrate how certain variables collected on FIA plots 

can be used for arriving at a more realistic estimate of nonreserved timberland area that 

might be available for timber harvesting. The four screening criteria are (1) roadless 

areas within nonreserved timberland, (2) areas greater than one mile from a maintained 

road, (3) slopes greater than 40 percent, and (4) nonstocked conditions. The assumption 

is that these four criteria present, to a certain degree, a deterrent to logging. After the 

6.5 million acres of nonreserved timberland have been deducted using the four criteria, 

less than 2.2 million acres (34 percent) remain.

Millions of visitors come to enjoy Wyoming’s National Parks every year. Yellowstone 

National Park is internationally famous, and is widely regarded as one of the most unique 

ecosystems in the world. When the large-scale fires struck in 1988, there was understandable concern about the impacts on the Park’s ecosystem. Although unprecedented 

in the 125-year history of the Park, the scientists reviewing the effects of the 1988 fires 

reminded the public that fires of such scale burned elsewhere in similar ecosystems during 

this century, and earlier in the landscape’s history. Much of the severely burned forest 

area naturally regenerated to extremely dense, young lodgepole pine stands. However, 

lodgepole pine is regarded as a fire-maintained subclimax species, and fire is critical for 

perpetuating the lodgepole pine ecosystem. The 2002 inventory statistics, especially the 

stand-age profile, support the conclusion that most of the Park’s landscape will evolve 

into what Yellowstone National Park resembled over 100 years ago.

The information in this report points to several opportunities for further analysis, 

investigation, and studies. There are significant differences in the stand-age distribution between reserved and nonreserved forest land. Analysis of where these old stands 

are located, what their species composition is, and evaluating their sustainability could 

help to address some of the old growth issues. The relationship between gross growth 

and mortality should be examined in more detail with emphasis on how the relationship 

differs on each of the National Forests. Gross growth and mortality are often used to 

explain why the live-tree inventory is increasing or decreasing, and can also indicate a 

state of forest health. Supply-related studies that examine how much of the live inventory 

is available for harvest, where this available inventory is located geographically, and 

what opportunities exist for harvesting this material would be of interest to the forest 

products industry. The per-acre analysis of growing-stock volume and sawtimber volume 

indicates that National Forest lands support significantly higher levels of live inventory 

compared to other ownership groups in Wyoming. The large-scale fires that occurred in 

1988 in Yellowstone National Park provided unique opportunities for evaluating how 

ecosystems respond to fire. The inventory data collected in Yellowstone between 1998 

and 2003 could be used for a broad-scale assessment of current stand conditions for 

those plots that showed evidence of fire-related disturbance in 1988.

Standard Forest Inventory and Analysis Terminology ______________

Note: For a more complete glossary, please go to: http://www.fs.fed.us/rm/ogden/

state_report/state_reports.html

Basal area (BA)—The cross-sectional area of a tree stem/bole (trunk) at the point where 

diameter is measured, inclusive of bark; BA is expressed in square feet. For timber 

species the calculation is based on diameter at breast height (d.b.h.); for woodland 

species it is based on diameter at root collar (d.r.c.).

Biomass—The quantity of wood fiber, for trees 1.0 inch in diameter and larger, expressed 

in terms of oven-dry weight. Includes aboveground portions of trees: bole/stem (trunk), 

bark, and branches. Biomass estimates can be computed for live and/or dead trees.
44 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

Bole—A trunk or main stem of a tree; seedlings and saplings are specified as having 

stems rather than boles. Woodland trees are also referenced as having stems.

Condition—Generally defined as an area of relatively uniform ground cover, such as 

homogeneous vegetative cover, meeting minimum size requirements.

Cubic-foot volume (merchantable)—See “Volume.”

Diameter at breast height (d.b.h.)—For timber species: the diameter of a tree bole/stem 

(trunk) measured at breast height (4.5 feet above ground); measured outside the bark. 

The point of diameter measurement may vary for abnormally formed trees.

Diameter at root collar (d.r.c.)—For woodland trees: the diameter of a tree stem(s) 

measured at root collar or at the point nearest the ground line (whichever is higher) 

that represents the basal area of the tree; measured outside the bark. For multistemmed woodland trees, d.r.c. is calculated from an equation that incorporates the 

individual stem diameter measurements. The point of diameter measurement may 

vary for woodland trees with stems that are abnormally formed. With the exception 

of seedlings, woodland stems qualifying for measurement must be at least 1.0 inch 

in diameter or larger and at least 1.0 foot in length.

Diameter class—A grouping of tree diameters (d.b.h. or d.r.c.) into classes of a specified range. For some diameter classes, the number referenced (for example, 4, 6, 8 

inches) is designated as the midpoint of an individual class range. For example, if 

2-inch classes are specified (the range for an individual class) and even numbers are 

referenced, the 6-inch class would include trees 5.0 to 6.9 inches in diameter.

Field/plot location—A reference to the sample site or plot—an area containing the 

field location center (LC) and all sample points. The mapped-plot design field location consists of four subplots and four microplots distributed over approximately 

2.5 acres.

• Subplot – A 1/24-acre fixed-radius area (24-foot horizontal radius) used to sample 

trees 5.0-inches d.b.h./d.r.c. and larger and understory vegetation.

• Microplot – A 1/300-acre fixed-radius plot (6.8-foot radius), located at the center 

of each subplot, and used to inventory seedlings and saplings.

Fixed-radius plot—A circular sample plot of a specified horizontal radius: 1/300 

acre = 6.8-foot radius (microplot); 1/24 acre = 24.0-foot radius (subplot).

Forest industry lands—See “Private lands.”

Forest land—Land that is at least 10 percent stocked with live tally tree species (timber 

or woodland species), including land that formerly had such stocking and that may 

be regenerated naturally or artificially. The minimum area for classification of forest 

land is 1 acre and 120 feet wide. Unimproved roads, trails, streams, and openings in 

forest areas are classified as forest land if they are less than 120 feet wide or 1 acre in 

size. For field use, sufficient tree crown cover (5 percent cover of tally tree species) 

or the presence of sufficient reproduction (40 tally tree species seedlings/saplings 

per acre) is used to represent 10 percent forest land stocking.

• Timberland—A subset of forest land, where the designated forest type is derived 

from timber species.

• Woodland—A subset of forest land, where the designated forest type is derived 

from woodland species.

• Nonstocked forest land—Formerly stocked forest land that currently has less 

than 10 percent stocking but has the potential to again become 10 percent stocked. 

Examples include recently harvested, burned, or windthrow-damaged areas.
USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 45

Forest type (historic IW-FIA method)—A classification of forest land based on and 

named for the tree species presently forming a plurality of live-tree stocking. Stocking 

is an expression of the extent to which growing space is effectively utilized by live 

trees. Some exceptions to the single predominant species concept used for classifying forest type apply to sites where (1) hardwoods and softwoods occur together in a 

stand, or (2) when Engelmann spruce and subalpine fir occur together in a stand, and 

in combination they compose the predominant live-tree stocking. When hardwoods 

(for example, maple, oak, or aspen trees) and softwoods (for example, Douglas-fir 

or ponderosa pine trees) occur together within a stand, forest type is determined as 

follows: First, the stocking percents of all softwoods are summed as a group, and 

then again for hardwoods, in order to determine which of the two overall groups has 

the most live-tree stocking. Next, the individual tree species from the group with 

the majority of stocking is selected as the forest type. When Engelmann spruce and 

subalpine fir (or corkbark fir) occur together in a stand, and in combination they 

constitute the predominant live-tree stocking, forest type is computed using the following criteria: First, all stocking percents are adjusted from an absolute base to a 

relative base, where the sum of all percents are equal to 100 percent maximum. Next, 

a stand is classified as an Engelmann spruce type if Engelmann spruce individually 

is greater than or equal to 20 percent relative stocking, and subalpine fir is less than 

20 percent relative stocking. For all other stands where subalpine fir and Engelmann 

spruce together have plurality, the stand is classified as the spruce-fir type.

Growing stock—A term often used in cubic foot volume tables to describe which trees 

are included in the net volume, annual growth, and annual mortality estimates. Includes 

growing-stock trees 5.0 inches d.b.h. and greater (excludes woodland species).

Growing-stock tree—See “Tree class – Sound tree.”

Growth—

• Gross annual growth—The average annual increase in the volume of live trees 

(less deductions for cull volume).

• Net annual growth—Gross annual growth minus average annual mortality 

volume.

Hardwood trees—Trees that are usually broad leaved and deciduous (leaves that fall 

off or shed at specific seasons).

Indian Trust lands—See “Private lands.”

Industrial wood—See “Logging residue/products.”

Large trees (Sawtimber trees)—See “Tree-size class.”

Logging residue/products—

• Industrial wood—All commercial roundwood products, excluding fuelwood.

• Logging residue—The unused portions within the merchantable sections of 

sound (growing-stock) trees cut or killed during logging operations.

• Primary wood-processing plants—An industrial plant that processes 

roundwood products, such as sawlogs, pulpwood bolts, or veneer logs.

• Pulpwood—Roundwood, whole-tree chips, or wood residues that are used 

for the production of wood pulp.

• Roundwood—Logs, bolts, or other round sections cut from trees.
46 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

Mapped-plot design—A sampling technique that identifies (maps) and separately classifies distinct “conditions” on the field location sample area. Each condition must 

meet minimum size requirements. At the most basic level, condition class delineations include forest land, nonforest land, and water. Forest land conditions can be 

further subdivided into separate condition classes if there are distinct variations in 

forest type, stand-size, stand origin, and stand density, given that each distinct area 

meets minimum size requirements.

Medium trees (Poletimber trees)—See “Tree-size class.”

Microplot—See “Field/plot location.”

Mortality tree—A standing or downed dead tree, 1.0 inch d.b.h./d.r.c. and larger, that 

was alive within the past 5 years.

National Forest System (NFS) lands—See “Public lands.”

National Park System (NPS) lands—See “Public lands.”

Net annual growth—See “Growth.”

Nonforest land—For the FIA mapped-plot design baseline inventory, nonforest land 

includes three main categories: (1) nontree land, (2) nonsampled tree land, and (3) 

other tree land.

• Nontree land—This is land that (1) has never supported tree cover/stocking 

sufficient for classification as forest land (for example, barren, alpine tundra), 

or (2) was formerly tree land, but has been converted to a nontree land status 

(for example, cropland, improved pasture). Other examples of nontree land 

are improved roads of any width, graded or otherwise regularly maintained for 

long-term use, and rights-of-way of all powerlines, pipelines, other transmission 

lines, and operating railroads. If intermingled in forest areas, unimproved roads 

and nonforest strips must be at least 120 feet wide and 1 acre in size to qualify 

as nontree land. This category also includes formerly stocked woodland areas if 

they are currently nonstocked due to a treatment (such as chaining, other land 

clearing). These areas are treated to eliminate woodland trees for the purpose of 

enhancing or providing for nonwood commodities or uses (such as increasing 

herbage production).

• Nonsampled tree land—This is land that currently meets the cover or stocking 

requirements for forest land, but human activity on the site will preclude the 

natural succession of the stand (areas that might be included in this category are 

golf courses, cemeteries, picnic grounds, orchards, Christmas tree plantations, 

and home yards with mowed lawns).

• Other tree land—Land that is 10 percent stocked with trees defined as “other 

tree species” (nontally tree species) but has less than 10 percent stocking or 5 

percent cover in tally tree species. Examples would include land stocked with 

tree species such as paloverde, tamerisk, or Russian olive. See “Other tree species.”

Nonindustrial private lands—See “Private lands.”

Nonreserved forest land—Forest land not withdrawn from management for production 

of wood products through statute or administrative designation.

Nonstocked forest land—See “Forest land.”

Other private lands—See “Private lands.”
USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 47

Other public lands—See “Public lands.”

Other tree species (nontally species)—All species classified as trees (Little 1979) that 

have not at this time been designated nationally by FIA as tally tree species. For the 

purposes of classifying forest land, only tally tree species are used to determine if 

minimal stocking requirements have been met. Other tree species include turbinella 

oak, Russian olive, acacia, etc. See “Nonforest land – Other tree land.”

Poletimber-size trees (Medium trees)—See “Tree-size class.”

Poletimber stands (Medium tree stands)—See “Stand-size class.”

Primary wood-processing plants—See “Logging residue/products.”

Private lands—

• Forest industry—Land owned by a company or an individual(s) operating a 

primary wood-processing plant.

• Indian Trust—American Indian lands held in fee, or trust, by the Federal Government, but administered for tribal groups or as individual trust allotments.

• Nonindustrial private—All private ownerships except forest industry.

• Other private—Privately owned lands other than forest industry or Indian 

Trust.

Productivity—Developed for timber species, the potential yield capability of a stand 

calculated as a function of site index (expressed in terms of cubic-foot growth per 

acre per year at age of culmination of MAI). Productivity values for forest land 

provide an indication of biological potential. Timberland stands are classified by 

the potential net annual growth attainable in fully stocked natural stands. Woodland 

stands are given a default value of 10 cubic feet per acre per year. For FIA reporting, 

Productivity Class is a variable that groups stand productivity values into categories 

of a specified range. Productivity is sometimes referred to as “Yield” or “Mean annual increment (MAI).”

Public lands—

• Miscellaneous Federal—Public lands administered by Federal agencies other 

than the Forest Service, U.S. Department of Agriculture, or the Bureau of Land 

Management, U.S. Department of the Interior.

• National Forest System (NFS)—Public lands administered by the Forest Service, 

U.S. Department of Agriculture, such as National Forests, National Grasslands, 

and some National Recreation Areas.

• National Park—Public lands administered by the Park Service, U.S. Department 

of the Interior, such as National Parks, National Monuments, National Historic 

Sites (such as National Memorials and National Battlefields), and some National 

Recreation Areas.

• Other public—Public lands administered by agencies other than the Forest 

Service, U.S. Department of Agriculture. Includes lands administered by other 

Federal, State, county, and local government agencies, including lands leased by 

these agencies for more than 50 years.

Pulpwood—See “Logging residue/products.”

Removals—The net volume of growing stock removed from the inventory by harvesting 

or other cultural operations (such as timber-stand improvement), by land clearing, or 
48 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

by changes in land use (such as a shift to wilderness).

Reserved land—Land withdrawn from management for production of wood products 

through statute or administrative designation. Examples include Wilderness areas 

and National Parks and Monuments.

Sapling and seedling stands—See “Stand-size class.”

Saplings—See “Tree-size class.”

Sawlog portion (timber species)—That part of the bole of sawtimber-size trees between 

a 1-foot stump and the sawlog top.

Sawtimber—A term often used in board-foot-volume tables to describe which trees 

are included in net volume, annual growth, and annual mortality estimates. Includes 

growing-stock trees 9.0 inches d.b.h. and greater for softwoods, and 11.0 inches d.b.h. 

and greater for hardwoods.

Sawtimber-size trees (Large trees)—See “Tree-size class.”

Sawtimber stands (Large tree stands)—See “Stand-size class.”

Seedlings—See “Tree-size class.”

Site index—A measure of forest productivity for a timberland tree/stand. Expressed 

in terms of the expected height (in feet) of site trees at an index age of 50 (or 80 for 

aspen and cottonwood). Calculated from height-to-age equations.

Site productivity—See “Productivity.”

Site tree—A timber species tree used to provide an index of site quality. Timber species 

selected for site index calculations must meet specified criteria with regards to age, 

diameter, crown class, and damage (for example, no broken or dead top damage).

Snag—A standing dead tree. See “Tree class – Hard dead tree and Soft dead tree.”

Softwood trees—Coniferous trees that are usually evergreen (retain leaves year-round), 

and having needlelike or scalelike leaves.

Stand—A community of trees that can be distinguished from adjacent communities 

due to similarities and uniformity in tree and site characteristics, such as age-class 

distribution, species composition, spatial arrangement, structure, and so forth.

Stand density—A relative measure that quantifies the relationship between trees per 

acre, stand basal area, average stand diameter, and stocking of a forested stand. Stand 

density index (SDI), a widely used measure developed by Reineke (1933), is an 

index that expresses relative stand density based on a comparison of measured stand 

values with some standard condition. For FIA reporting, the SDI for a site is usually 

presented as a percentage of the maximum SDI for the forest type. Site SDI values 

are sometimes grouped into SDI classes of a specified percentage range. Maximum 

SDI values vary by species and region.

Standard error—An expression that denotes the precision of an estimate, obtained by 

statistical sampling methods.

Stand-size class—A classification of forest land based on the predominant diameter 

size of live trees presently forming the majority of live-tree stocking. Classes are 

defined as follows:

• Sawtimber stand (Large-tree stand)—A stand at least 10 percent stocked with 

live trees, in which half or more of the total stocking is from live trees 5.0 inches 

or larger in diameter, and with sawtimber (large tree) stocking equal to or greater 
USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 49

than poletimber (medium tree) stocking.

• Poletimber stand (Medium-tree stand)—A stand at least 10 percent stocked 

with live trees, in which half or more of the total stocking is from live trees 5.0 

inches or larger in diameter, and with poletimber (medium tree) stocking exceeding sawtimber (large tree) stocking.

• Sapling/seedling stand—A stand at least 10 percent stocked with live trees, in 

which half or more of the total stocking is from live trees less than 5.0 inches in 

diameter.

• Nonstocked stand—A formerly stocked stand that currently has less than 10 

percent stocking, but has the potential to again become 10 percent stocked. For 

example, recently harvested, burned, or windthrow-damaged areas.

Stocking—An expression of the extent to which growing space is effectively utilized 

by live trees.

Stocking condition (class)—A classification of forest land used to provide an indication of the extent to which a site is being utilized by live trees (including live cull 

trees).

• Overstocked—Sites at least 100 percent stocked.

• Fully stocked—Sites that are 60 to percent stocked.

• Medium to fully stocked—Sites that are 35 to 60 percent stocked.

• Poorly stocked—Sites that are 10 to 35 percent stocked.

• Nonstocked—Sites with a stocking value less than 10.

Subplot—See “Field/plot location.”

Tally trees—Tree species that have been selected to be included in the field inventory/

sample because they occur in a tree growth form throughout much of their range 

(Little 1979). Tally tree species are categorized as “timber” or “woodland” trees. Tally 

trees are evaluated for a variety of items (such as crown class, crown ratio, damage, 

rotten/missing material, form defect) and measurements (such as diameter, height) 

are taken on each tally tree. This information is used to obtain estimates of volume, 

growth, and mortality for the sample location. Tally tree data can also be used to 

obtain estimates for other site variables, such as site quality and health.

Timber species—Tree species traditionally used for industrial wood products. These 

include all species of conifers, except pinyon and juniper. Hardwoods included are 

aspen, box elder, cottonwood, and paper birch. Timber species are measured for 

diameter at breast height.

Timberland—See “Forest land.”

Tree class—A classification system based on a tree’s physical characteristics.

• Live trees are classified for Tree Class as follows:

– Sound tree (Growing-stock tree)—A live timber species, 5.0 inches d.b.h. 

or larger, with less than two-thirds (67 percent) of the merchantable volume 

cull, and containing at least one solid 8-foot section, reasonably free of form 

defect, on the merchantable portion of the tree. A live timber species sapling 

(1.0 to 4.9 inches d.b.h.) is also included in this category if it is expected 

to become a sound live tree, 5.0 inches d.b.h. or larger, with good form and 

vigor.

– Rough tree—A live timber species, 5.0 inches d.b.h. and larger, with two-
50 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

thirds (67 percent) or more of the merchantable volume cull, and more than 

half of this cull is due to sound dead wood volume loss, or severe form-defect 

volume loss (such as severe sweep, crook, forks). Also, a live timber species sapling (1.0 to 4.9 inches d.b.h.) that is not expected to become a sound 

(growing-stock) tree due to defect, or a timber species (5.0 inches d.b.h. and 

larger) that does not now, or prospectively, have at least one solid 8-foot section, reasonably free of form defect, on the merchantable portion.

– Rotten tree—A live timber species, 5.0 inches d.b.h. and larger, with twothirds (67 percent) or more of the merchantable volume cull, and more than 

half of this cull is due to rotten and/or missing material.

– Live woodland tree—A live tree of any woodland species.

• Dead trees (timber or woodland species) are classified for Tree Class as 

follows:

– Hard dead tree (Salvable dead tree)—A standing dead tally tree, 1.0 

inch d.b.h./d.r.c. or larger, that has a minimum of one-third of the original 

merchantable volume sound (less than two-thirds rotten and/or missing 

material). Also, a down-dead tally tree, 1.0 inch d.b.h./d.r.c. or larger, with a 

minimum of one-third of the original merchantable volume sound and intact. 

See “Downed tree” and “Standing tree.”

– Soft dead tree (Nonsalvable dead tree)—A standing dead tree, 1.0 inch 

d.b.h./d.r.c. or larger, that has less than one-third of the original merchantable volume sound (more than two-thirds rotten/missing material). Also, a 

down-dead tree, 1.0 inch d.b.h./d.r.c. or larger, with less than one-third of 

the original merchantable bole sound and intact. See “Downed tree” and 

“Standing tree.”

Tree-size class—A classification of trees based on d.b.h. for timber species and d.r.c. 

for woodland species. For woodland trees, with the exception of seedlings, stems 

qualifying for measurement must be at least 1.0 inch in diameter or larger and at 

least 1.0 foot in length:

• Seedling—An established tree smaller than 1.0 inch d.b.h. for timber species 

or 1.0 inch d.r.c. for woodland trees, and at least 4 inches tall for softwoods and 

12.0 inches tall for hardwoods.

• Sapling—A timber species 1.0 to 4.9 inches d.b.h.; also, a single-stemmed 

woodland tree 1.0 to 4.9 inches d.r.c., or a multistemmed woodland tree with a 

cumulative d.r.c. of 1.0 to 4.9 inches.

• Poletimber-size tree or medium tree—A timber species at least 5.0 inches 

d.b.h., but smaller than 9.0 inches d.b.h. for a softwood, and smaller than 11.0 

inches d.b.h. for a hardwood. A woodland tree 5.0 to 8.9 inches d.r.c. (single 

stem measurement or computed multistem measurement) is also included in this 

category.

• Sawtimber-size tree or large tree—A timber species that is at least 9.0 inches 

d.b.h. for a softwood, and at least 11.0 inches d.b.h. for a hardwood. A woodland 

tree 9.0 inches d.r.c. and larger (single stem measurement or computed multistem 

measurement) is also included in this category.

Volume for Timber Species—

• Annual mortality volume—The net volume contained in timber species (standing or down) that have died over a 1-year period. This estimate is based on a 
USDA Forest Service Resour. Bull. RMRS-RB-6. 2005 51

5-year average. Mortality volume for timber species can be calculated in terms 

of cubic feet or board feet. See “Mortality tree.”

• Board-foot volume—A board-foot is a unit of measure indicating the amount of 

wood contained in an unfinished board 1-foot wide, 1-foot long, and 1-inch thick. 

Board-foot volume is computed for the sawlog portion of a sawtimber-size tree; 

the sawlog portion includes the part of the bole on sawtimber-size tree from a 1-

foot stump to a minimum sawlog top of 7 inches diameter outside bark (d.o.b.) for 

softwoods, or 9 inches d.o.b. for hardwoods. Net board-foot volume is calculated 

as the gross board-foot volume in the sawlog portion of a sawtimber-size tree, 

less deductions for cull (limited to rotten/missing material and form defect cull 

deductions, referred to as the board-foot merchantability factor). Board-foot 

volume estimates are computed in both Scribner and International 1⁄4-inch rule, 

and can be calculated for live and/or dead (standing or down) trees.

• Cubic-foot volume (merchantable)—A cubic foot is a unit of measure indicating 

the amount of wood contained in a cube 1 by 1 by 1 foot. Cubic-foot volume is 

computed for the merchantable portion of a timber species tree; the merchantable 

portion includes that part of a bole from a 1-foot stump to a minimum 4-inch 

top, d.o.b. Net cubic-foot volume is calculated as the gross cubic-foot volume 

in the merchantable portion of a tree, less deductions for cull (limited to rotten/

missing cull deductions, referred to as the cubic-foot merchantability factor). 

Merchantable cubic-foot volume estimates can be calculated for live and/or dead 

(standing or down) trees.

Volume for Woodland Trees—

• Annual mortality volume—The net volume contained in woodland trees (standing or down) that have died over a 1-year period. This estimate is based on a 

5-year average. Mortality volume for woodland trees is calculated in cubic feet. 

See “Mortality tree.”

• Cubic-foot volume—A cubic-foot is a unit of measure indicating the amount 

of wood contained in a cube 1 by 1 by 1 foot. Woodland cubic-foot volume is 

computed for trees 5.0 inches and larger in diameter.

• Dead volume—For dead woodland trees, this volume is equal to gross 

cubic-foot volume. For live woodland trees, dead volume is calculated as 

gross cubic-foot volume times the field crew estimate of percent sound dead 

volume loss. Cull deductions are limited to the merchantable portion of a 

tree.

• Net volume—The gross cubic-foot volume of live woodland trees, less deductions for rotten and missing material. This estimate includes volume for 

dead material on live trees. Cull deductions are limited to the merchantable 

portion of a tree.

Water—In terms of Ground Cover Classification, water includes streams, sloughs, 

estuaries, and canals more than 30 feet in width; and, lakes, reservoirs, and ponds 

more than 1 acre in size. Ephemeral and intermittent streams are classified as land. 

Water is further classified as “census water” or “noncensus” water as follows:

• Census water—Rivers, streams, sloughs, estuaries, and canals, more than 200 feet 

wide and 4.5 acres and larger in size; only portions of rivers and streams meeting 

the definition criteria are considered census water. Other census water includes 

lakes, reservoirs, and ponds more than 4.5 acres and larger in size. Portions of 

braided streams meeting the census water definition criteria and more than 50 

percent water at normal high-water level are also considered census water.
52 USDA Forest Service Resour. Bull. RMRS-RB-6. 2005

• Noncensus water—Portions of rivers, streams, sloughs, estuaries, and canals 

that are 30 to 200 feet wide and at least 1 acre in size; and lakes, reservoirs, and 

ponds 1 to 4.5 acres in size. Portions of rivers and streams not meeting the criteria for census water, but at least 30 feet wide and 1 acre in size, are considered 

noncensus water. Portions of braided streams not meeting the criteria for census 

water, but at least 30 feet in width and 1 acre in size, and more than 50 percent 

water at normal high-water level are also considered noncensus water.

Wilderness—An area of undeveloped land currently included in the Wilderness System, managed to preserve its natural conditions and retain its primeval character and 

influence.

Woodland—See “Forest land.”

Woodland species—Tree species that are not usually converted into industrial wood 

products. Common uses of woodland trees are fuelwood, fenceposts, and Christmas 

trees. These species include pinyon, juniper (except western juniper), mesquite, locust, 

mountain-mahogany, Rocky Mountain maple, bigtooth maple, desert ironwood, and 

most oaks (chinkapin oak is classified as a timber species). Because woodland trees 

are extremely variable in form, diameter is measured at the root collar.
