Forest statistics for Southwest Louisiana parishes
These tables were derived from data obtained during a 1984 inventory of 11 parishes comprising the Southwest Unit of Louisiana (fig. 1). The data on forest acreage and timber volume were secured by a systematic sampling method involving a forest-nonforest classification on aerial photographs and on-the-ground measurements of trees at sample locations. The sample locations were at the intersections of a grid of lines spaces 3 miles apart. At each forest location, per acre estimates were obtained from a 5 BA 37.5 point samples.
