Abstract	The objective of this study was to use spatial statistics to quantify the effects of desertification on the distribution of biomass and available nitrogen in Chihuahuan desert black grama (Bouteloua eriopoda) grassland, which has been invaded by honey mesquite (Prosopis glandulosa) shrubland. This research is a portion of analysis of spatial patterns and interrelationships of ecological variables across a desertification gradient, with the larger goal of being to improve our understanding of the mechanisms underlying desertification in southwestern ecosystems. This study tested the sensitivity of "Geostatistics" and "Spatial statistics" to detect subtle differences between ecosystems, such as those occurring across a continuous gradient of desertification.
