Forest statistics for east Oklahoma counties - l993

Abstract

This report contains the statistical tables and figures derived from data obtained during a recent inventory of east Oklahoma. The multiresource inventory included 18 counties and two survey regions. Data on forest acreage and timber volume involved a three-step procedure. First, estimate of forest acreage were made for each county using aerial photographs. Classification of forest-nonforest points was accomplished, each representing approximately 230 acres. Second, these estimates were adjusted based on ground observations at 2,762 sample locations. Finally, field measurements were made at forest locations on the intersections of grid lines spaced 3 miles apart. At each forest locations, per-acre estimates were obtained from trees measured on ten 37.5 basal area factor prism points.
