Excerpt from Timber Resource Statistics for Midsouth Counties, 1971 This report tabulates information from a new forest inventory of counties in central Ala bama. The tables are intended for use as source data in compiling estimates for groups of coun ties. Because the sampling procedure is de signed primarily to furnish inventory data for the State as a whole, estimates for individual counties have limited and variable accuracy. The data on forest acreage and timber vol ume were secured by a systematic sampling method involving a forest-nonforest classifica tion on aerial photographs and ou-the-ground measurements of trees at sample locations. The sample locations were at the intersections of a grid of lines spaced 3 miles apart. At each forested location, 10 small plots were uniform ly distributed on an area of about 1 acre.
