ABSTRACT
A new measure of the forest resource has been added to the fourth forest inventory of Maryland. The inventory, which was conducted in 1985-86, included estimates of aboveground tree biomass on timberland. There are approximately 265 million green tons of wood and bark in the aboveground portion of all trees, an average of 109 green tons per acre statewide. Approximately 63 percent or 167 million green tons is in growing stock, and nearly 37 percent or 98 million green tons is nongrowing- stock (growing-stock tops, saplings, cull trees, and salvable dead trees) material.
FOREWORD
The fourth inventory of Maryland was under the overall direction of John R. Peters, Project Leader of the Forest Inventory and Analysis Unit. Thomas W. Birch assisted in the development and administration of the operating plan. Charles T. Scott was responsible for the design of the inventory and sample selection. David J. Alerich supervised the interpretation of aerial photos and collection of data. He was assisted by Joseph G. Reddan. Members of the field staff were:

All Trees
Dry weight averages 56 percent of green weight for all species on a statewide basis.
There are more than 265 million green tons of aboveground biomass in all trees. Over 98 percent, or 260 million green tons, is in live trees.
Growing stock accounts for 167 million tons, 63 percent of the net green weight of all trees.
Nongrowing stock accounts for 98 million tons, or 37 percent of the net green weight of all trees. Fifty-nine percent of the nongrowing stock is in growing-stock tops, 16 percent is in rough and rotten cull trees, 20 percent is in saplings, and 5 percent is in salvable dead trees.
Hardwoods make up 86 percent, or 227 million green tons, of the net aboveground biomass of all trees.
Net aboveground biomass for all trees averages 109 green tons per acre in Maryland, and ranges from a low of 83 green tons per acre in Wicomico County to a high of 146 green tons per acre in Caroline/Talbot Counties.
All Live Trees
Sawtimber stands contain 216 million green tons, or 83 percent, of above- ground biomass of all-live trees.
The Oak/hickory forest-type group contains the largest amount of above- ground tree biomass (170 million green tons).
Red maple is the leading species in terms of aboveground biomass as well as cubic-foot volume. This species accounts for 11 percent of the aboveground biomass of all live trees. Loblolly pine is the leading soft- wood species and accounts for 8 percent of the aboveground biomass.
Cull and Salvable Dead
Cull and salvable dead trees average 8.2 green tons per acre of timber- land, and range from a low of 3 green tons per acre in Wicomico County to a high of 14 green tons per acre in Allegany County.
The Elm/ash/red maple forest-type group has the highest average tons per acre (13.3) of cull and salvable dead material. The Loblolly/shortleaf group has the lowest average at just 3.1 tons per acre.
Introduction
The USDA Forest Service completed the fourth in- ventory of Maryland’s forest resources in 1986. Pre- vious inventories were conducted in 1950, 1964, and 1976.
The inventories are conducted under the authority of the McSweeney-McNary Forest Research Act of 1928 and subsequent acts including the Renewable Resources Planning Act of 1974 and the Renewable Resources Research Act of 1978.
The statistics presented in this report are a summa- ry of data collected on new field plots established during the fourth inventory and on a remeasured subsample of plots established during the previous inventories. The new-plot sample consisted of 602 ground plots randomly selected from 18,355 photo points classified by land use and cubic-foot volume class. The remeasured sample consisted of 550 plots from the third survey. A total of 1,152 points was sampled for an average of one plot for every 5,465 acres of land area.
Data were collected, processed, and analyzed by the Forest Inventory and Analysis staff. A complete list of available biomass tables is included in this report. These tables are available on microfiche by state, geographic unit (Fig. 1), and county.

Methods
Traditionally, forest resource data have been col- lected to describe the forest in terms of its timber production capabilities. Board-foot and cubic-foot measures of volume (Fig. 2) were and are adequate for that purpose.
Although timber production is still considered by many to be the primary use of forest land, there are many data users that are also interested in how the resource can be used for energy production, fiber- based products, wildlife, or recreation. Because board-foot and cubic-foot volume estimates do not describe the forest resource broadly enough, biomass estimates have been built into the stand- ard USDA Forest Service inventory procedure (Fig. 2).
Figure 2.--Volume and weight relationships of hard- wood aboveground tree biomass components.
Users of biomass data are interested in both green and dry weight as well as in the weight of various tree components. Two criteria were established for selecting a set of biomass equations to cover the species encountered in the Northeast. First, the biomass equations must provide both green weight and dry weight, and second, the selected equations must use only diameter at breast height as an inde- pendent variable.
Three sets of regression equations were chosen from the literature that fit the two criteria: Monteith (1979) collected data from New York, Wiant and others (1977) collected data from West Virginia, and __ Young and others collected data from Maine. The equations cover the range of species encountered in the Northeast. Where a regression equation for a species has been published by more than one au- thor, Young and others (1980) is used as the prima- ry source, followed by Wiant and others (1977) and Monteith (1979).
Young and others (1980) is the source of tree biomass regression functions for softwoods: bal- sam fir, eastern white pine, red pine, spruce, hem- lock, northern white-cedar, and larch. The source of tree-biomass regression functions for hardwoods is: red maple, yellow birch, and aspen from Young and others (1980); sugar maple, American beech, and white ash from Monteith (1979); hickory, yellow- poplar, black cherry, white oak, scarlet oak, chest- nut oak, northern red oak, and black oak from Wiant and others (1977).
Although all of the equations provide an estimate of total tree biomass (above stump), each equation uses different standards. Monteith’s equation (8) assumes a 1-foot stump, whereas Wiant’s (2) and Young's (1) equations assume a 6-inch stump. Also, foliage weight may be included or ignored depend- ing on which equation is being used:
Ln Y = bt b,Ln(D) (1) LOG, .Y = LOG,,b,+ b,LOG,,(D) (2)
where: Y = green weight in pounds D = diameter at breast height in inches
Y = by+ b,(D) + b,(D)? (3)
where: Y = green weight in kilograms D = diameter at breast height in millimeters
The weights in stumps and foliage are commonly quite small, and in the case of foliage weight, varia- tion is too great to develop meaningful averages (Keays 1971). Therefore, biomass statistics result- ing from the use of the selected equations may be slightly over- or under-estimated depending on the species. The form of the equations is shown in the previous tabulation and the regression coefficients can be found on page 9.
All species that did not have specific biomass coeffi- cients were grouped with species that had similar green and dry densities. (See page 10.)
The weight of the merchantable stem was derived by multiplying the total tree weight by a calculated percentage. The percentage is diameter and softwood/hardwood dependent and is based on historical inventory data. The estimate for tops and branches was developed by taking the difference between above-stump biomass from the weight re- gression equations and the independent estimate of merchantable stem biomass.
Estimates of area, volume, and aboveground tree biomass have been summarized in this report. The Statistics are presented by forest-type group, species or species group, and diameter group and are provided at the state and county level.
Reliability of Estimates
The data in this report were based on a carefully designed sample of forest conditions throughout Maryland. The field crews did not measure every tree nor examine every acre in the State and so the data are estimates. Therefore, zeros in any table cell indicate that the condition did not appear in the sample, or that the amount encountered was negli- gible. They do not necessarily mean that the condi- tion does not exist.
There are two important sources of error to consider when looking at the estimates provided in this re- port: (1) the error associated with estimation from sample plots, and (2) the error associated with com- bining independent estimates. Some of the errors associated with estimation from sample plots are included in the tables and are called sampling error. We are not able to calculate a value for the error associated with combining independent estimates.
Briefly, here is an example of how the sampling error is used to indicate reliability. The estimate of above- ground biomass of all trees on timberland in Mary- land is 265 million green tons. It has an associated sampling error of 2.7 percent, or 7.2 million green tons. This means that if the survey were repeated, the odds are 2 to 1 (66 percent probability) that the estimate would be between 257.8 and 272.2 million green tons (265 + 7.2). Similarly, the odds are 19 to 1 (95 percent probability) that the estimate would be within + 14.4 million green tons.
State estimates have the smallest sampling errors and therefore are the most reliable. Geographic unit estimates are the next most reliable followed by county estimates. For example, the sampling error of aboveground tree biomass for Maryland is 2.7 percent, while the sampling error for Allegany Coun- ty is 5.7 percent. County estimates are expected to be considerably less reliable than state estimates. The state estimates are based on a larger sample than county estimates, and as the sample size used to obtain the estimate decreases in relation to the population size, the sampling error is expected to increase.
Some of the estimates have sampling errors that are greater than 25 percent and may not be useable. Any estimate with a sampling error of 50 percent or more would not be significantly different from zero,
and those estimates with errors between 25 and 50 percent are suspect. Therefore, any estimates that have errors exceeding 25 percent should be used with caution.
The second important source of error occurs when two independent estimates are used to derive a third estimate. The biomass in tops and branches has been derived in this manner. The estimate of the merchantable stem biomass was subtracted from the estimate of total above-stump biomass to yield and estimate of the biomass in tops and branches. Consequently, the estimates of tops and branches should be used with caution.

Stand-size class. A classification of forest land based on the size class (that is, seedlings, saplings, poletimber, or sawtimber) of all live trees in the area.
Stocking. The degree of occupancy of land by trees, measured by basal area and/or number of trees in a stand compared to the basal area and/or number of trees required to fully use the growth potential of the land (or the stocking standard). In the Eastern United States this standard is 75 square feet of basal area per acre for trees 5.0 inches d.b.h. and larger, or its equivalent in numbers of trees per acre for seedlings and saplings.
Two Categories of stocking are used in this report: all live trees and growing-stock trees. The relation- ships between the classes and the percentage of the stocking standard are: nonstocked = 0 to 9, poorly stocked = 10 to 59, moderately stocked = 60
_to 99, fully stocked = 100 to 129, and overstocked = 130 to 160.
Stump. The main stem of a tree from ground level to 1 foot above ground level, including the wood and bark.
Timberland. Forest land producing or capable of producing crops of industrial wood (more than 20 cubic feet per acre per year) and not withdrawn from timber utilization. Formerly known as commercial forest land.
Top. The wood and bark of a tree above the mer- chantable height (or above the point on the stem 4.0 inches in diameter outside bark). It generally in- cludes the uppermost stem, branches, and twigs of the tree, but not the foliage.
Tree class. A classification of the quality or condition of trees for sawlog production. Tree class for saw- timber trees is based on their present condition. Tree class for poletimber trees is a prospective determination--a forecast of their potential quality when they reach sawtimber size (11.0 inches d.b.h. for hardwoods, 9.0 inches d.b.h. for softwoods).
Trees. Woody plants that have well-developed stems and are usually more than 12 feet in height at maturity.
Upper-stem portion. That part of the main stem or fork of a sawtimber tree above the sawlog top to a diameter of 4.0 inches outside bark, or to the point where the main stem or fork breaks into limbs.

1,000,000 acres = 404,686 hectares
1 board foot = 0.00348 cubic meters
1 board feet = 3,480 cubic meters
1,000 board feet = 3.48 cubic meters
1,000,000 board feet = 3,480 cubic meters
1 cubic foot = 0.028317 cubic meters
1,000 cubic feet = 28,317 cubic meters
1 cord (wood, bark, and air space) = 3.6246 cubic meters 1 cord (solid wood, pulpwood) = 2.4069 cubic meters
1 cord (solid wood, other than pulpwood) = 2.2654 cubic meters 1,000 cords (pulpwood) = 2,406.9 cubic meters
1,000 cords (other products) = 2,265.4 cubic meters
1 inch = 2.54 centimeters or 0.0254 meters
1 foot = 30.48 centimeters or 0.3048 meters
1 mile = 1.609 kilometers
1 square foot = 929.03 square centimeters or
1 square foot per acre basal area = 0.229568 square meters per hectare
1 ton = 907.1848 kilograms
1,000 tons = 907.1848 metric tons
Breast height = 1.4 meters above ground level
Although 1,000 board feet is theoretically equivalent to 2.36 cubic meters, this is true only when a board foot is actually a piece of wood with a volume 1/12 of a cubic foot. The International 1/4-inch log rule is used by the USDA Forest Service in the East to estimate the product potential in board feet. The reliability of the estimate obtained by conversion will vary with the size of the log measure. The conversion given here, 3.48 cubic meters, is based on the cubic volume of a log 16 feet long and 15 inches in diameter inside bark (d.i.b.) at the small end. This conversion could be used for average comparisons when accuracy of 10 percent is acceptable. Because the board foot unit is not a true measure of wood volume and because products other than di- mension lumber are becoming Important, this unit may eventually be phased out and replaced by the cubic meter.
