Assessing and monitoring rangeland condition in extensive pastoral regions using satellite remote sensing and GIS techniques: an application to the Ceres Karoo region of South Africa

Abstract

Describes the use of satellite remote sensing and GIS techniques in applying a localized range condition assessment methodology based on fence-line contrasts. The approach was to compute six dissimilarity indices for data on vegetation cover and composition from paired, site-specific surveys across farm boundaries. Illustrates with maps, tables, photographs, graphs and images
