Description
Summary:Current environmental issues such as declining biodiversity, sustainability of ecosystems, and global atmospheric change are manifestations of multiple stresses. The need to establish baseline ecological conditions as a reference for assessing future change has grown more acute with the increasing complexity and scale of environmental issues. In the United States the Environmental Monitoring and Assessment Program is an interagency effort to provide a long-term monitoring program to determine status and trends in ecological resources at regional and national scales. This paper discusses the indicator framework for this monitoring program, the linkage between indicator selection and successful assessment, and the status of indicator selection in 1992.
