Development Prototype: Puget Sound Ecosystem Portfolio Model

About Us

The PSEPM is part of a suite of Ecosystem Portfolio Model (EPM) tools developed at the USGS Western Geographic Science Center that provide web-based decision-support at the regional level. The South Florida Ecosystem Portfolio Model is a regional land-use planning web tool that integrates ecological, economic, and social information and values of relevance to decision-makers and stakeholders. The Santa Cruz Watershed Ecosystem Portfolio Model characterizes ecological, economic, and societal endpoints that are sensitive to climate patterns, regional water budgets, and regional land-use/land-cover change in the Santa Cruz Watershed located in Arizona and Sonora, Mexico.
