1 Ecological Site Descriptions Foundation for Resource Management Decisions George Peacock Grazing Lands Technology Institute USDA-NRCS

2 Looking across any landscape it is not difficult to recognize that some parts are different from other parts in the kinds and amount of vegetation

3 Information on native plant communities for Ecological Restoration

4 Information for predicting change in plant communities due to disturbances

5 Information on hydrologic changes as plant community composition changes  Infiltration rates  Aquifer recharge  Surface runoff  Downstream flooding  Infiltration rates  Aquifer recharge  Surface runoff  Downstream flooding

48 MEETING MANAGEMENT OBJECTIVES Similarity Index Rangeland Health Trend Rating indicating how nearly the present vegetation resembles desired plant community. Rating indicating how nearly the present vegetation resembles desired plant community. Indicates direction of plant community change. Range trend Planned trend Indicates direction of plant community change. Range trend Planned trend Indicator of how the ecological processes of the site are functioning. Indicator of how the ecological processes of the site are functioning.

49 Ecological Site Descriptions Provide: A common framework for communication of resource information among disciplines, agencies, and organizations. Information describing the interactions among soils, vegetation, and land management. A foundation to assess the condition of current resources and monitor changes. A framework to assess management opportunities and predict the outcome of management decisions. A framework for transferring experience and knowledge.
