Characterization of Ecosystems Exposure to Environmental Stressors: Development of Landscape Indicators for the Chihuahuan Desert


Remotely sensed and ground-based data are being used to develop indicators of ecosystem health and exposure to landscape stress. The project is developing analytical techniques to integrate information about stress across scales that will lead to regional risk assessment tools. Previous research at the landscape scale has addressed the question of "how to identify the threshold for degradation that may lead to an alternate stable but degraded state." Current research is focused on regional analysis using remotely sensed imagery and ground studies to examine relationships among degraded states, geomorphology – lithology, and man-made features that support the livestock industry in the western U.S.
