Abstract
These tables were derived from data obtained during a 1982 inventory of 21 counties comprising the Southeast Unit of Alabama (fig. 1). The data on forest acreage and timber volume were secured by a systematic sampling method of involving a forest-nonforest classification on aerial photographs and on-the-ground measurements of trees at sample locations. The sample locations were at the intersection of a grid of lines spaced 3 miles apart. At each forest location, per acre estimates were obtained from 5 BA 37.5 point samples.
