NEWS NOTES ON SUSTAINABLE WATER RESOURCES USGS Priority Ecosystems https://access.usgs.gov/about.html ; The mission of Priority Ecosystem Science (PES) is to provide science in support of adaptive management of ecosystems that have near-term societal concern and significant long-term societal value. Studies are designed to serve local ecosystem management needs and to provide knowledge and approaches transferable to similar ecosystems across the Nation. PES efforts focus in areas where new integrated science approaches can be developed to address the needs of a diverse group of decision-makers and to meet Department of the Interior's responsibilities to manage the Nation's lands. Activities require collaboration and integration of expertise from the four USGS disciplines, Biology, Geology, Geography, and Water to achieve a system-scale understanding of the natural and anthropogenic factors affecting ecosystems and to better understand the interactive nature of resources and the environment. On a larger scale, PES efforts contribute to a broader capability needed to understand and assess the health of the Nation's ecosystems. Current PES study units include the Greater Everglades, San Francisco Bay, Chesapeake Bay, the Mojave Desert, and the Platte River.
