Ecological Status and Trends Program: EPA's Approach to Monitoring Condition of the Nation's Ecosystems

摘要

The U.S. Environmental Protection Agency (EPA) is initiating an Environmental Monitoring and Assessment Program (EMAP) to monitor the status and trends of the nation's near coastal waters, forests, freshwater wetlands, surface waters, and agroecosystems. The program is also intended to evaluate the effectiveness of Agency policies at protecting ecological resources occurring in these systems. Monitoring data collected for all ecosystems will be integrated for national status and trends evaluations.
