Site productivity—A measure of the inherent capability of 
land to grow timber based on fully stocked natural stands. 
High sites—Land capable of growing 85 cubic feet of 
wood per acre per year in fully stocked natural stands. 
Medium sites—Land capable of growing 50 to 85 cubic 
feet of wood per acre per year in fully stocked natural 
stands. 
Low sites—Land capable of growing 20 to 49 cubic 
feet of wood per acre per year in fully stocked natural 
stands. 
Softwoods—Coniferous trees, usually evergreen, having 
needles or scalelike leaves. 
South—A geographic area that includes 12 Southern States 
divided into two regions. 
Southeast region—The geographic area that includes

Stocking—The degree of occupancy of land by trees,

area and/or number of trees required to fully utilize the 
growth potential of the land.

Timberland—Forest land which is producing or is capable 
of producing crops of industrial wood and not withdrawn 
from timber utilization by statute or administrative 
regulation. (Note: Areas qualifying as timberland have the 
capability of producing in excess of 20 cubic feet per acre 
per year of industrial wood in natural stands. Areas currently 
inaccessible and inoperable are included.) 
Timber removals—The net volume of growing stock 
trees removed from the inventory by harvesting; cultural 
operations, such as timber stand improvement; land 
clearing: or changes in land use. 
Timber supplies—The volume of roundwood harvested or 
available for harvest in the future. Includes roundwood from 
growing stock and nongrowing stock sources. 
Urban and other areas—Areas within the legal boundaries 
of cities and towns; suburban areas developed for residen- 
tial, industrial, or recreational purposes; school yards; 
cemeteries; roads, railroads; airports; beaches, power lines,
