Ecological sites comprise a land classification system that describes ecological potential and ecosystem dynamics of land areas. They are used to stratify the landscape and organize ecological information for purposes of monitoring, assessment, and management. This page provides some definitions for ecological site descriptions (ESDs) and provides tools and literature pertaining to their development. A comprehensive guidance document for ESD development for the United States is being produced via cooperation of responsible federal agencies and is an active area of research at the Jornada Experimental Range. There are many ways ESD concepts can be developed and applied outside of the United States.
