AbstractIn 1988, personnel with the Jornada Experimental Range in southern New Mexico chemically treated a large grassland area for mesquite. he treatment was successful in killing nearly 100% of the mesquite plants present. Since treatment plant recovery and invasion has resulted in current mesquite densities of about 3% cover. We accessed 90 dates of vegetation index information derived from meteorological satellite imagery recorded over seven growing seasons. The data were used to track the density of mesquite from pre-treatment through five years post-treatment. Differences in seasonal landscape greenness characteristics derived by analysis of the satellite data show the effect of the chemical treatment, as well as the re-invasion of the mesquite. This research demonstrates the potential utility of satellite derived information in assessing vegetation response to implementation of range management strategies. Similar techniques applied over longer time periods could be utilized to monitor ecosystem health and desertification processes.
