A Test of Stereophotographic Sampling in Grasslands

Color stereophotography was used to sample a grassland vegetation type for species presence and for cover. Square foot estimate plots were used as a check. Three-Pee sample selection was also tested. Species identification proved difficult in dry, weathered vegetation. Cover estimates were lower for single stemmed and linear leaved weathered plants in the stereophotographic sample than in the square foot field estimate. Three-Pee sampling gave similar results to complete estimates.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
