ABSTRACT- The EPA's Environmental Monitoring and Assessment Program (EMAP) has been developing a set of spatial metrics for a 12-State area of the western United States to evaluate ecological conditions of terrestrial ecosystems. One of the primary goals of this project is to link observed conditions of terrestrial ecosystems to surface water conditions across this broad regional area. This paper highlights analytical approaches used to evaluate terrestrial ecosystem condition, as well as measures of stressors that might account for observed conditions.

KEY WORDS: geographic information systems, western EMAP, remote sensing, landscape assessments
