Abstract:Ranked-set sampling was considerably more efficient than random sampling for estimating weights of browse and herbage in a pine-hardwood forest of east Texas. The procedure was to establish sets of three closely grouped quadrats, visually rank quadrats within sets as highest, intermediate, or lowest in forage weight, and then clip and weigh forage from one quadrat of each set.
