USGS National Research Program

Scenes from USGS NRP Tucson. The National Research Program (NRP) conducts basic and problem oriented hydrologic research in support of the mission of the U.S. Geological Survey (USGS). Results of NRP's long-term research investigations often lead to the development of new concepts, techniques, and approaches that are applicable not only to the solution of current water problems, but also to future issues that may affect the Nation's water resources. The NRP is located principally in Reston, VA, Denver, CO, and Menlo Park, CA. A Chief, Branch of Regional Research, (BRR) at each location is responsible for managing the program.

The USGS NRP offices in Tucson, AZ is now closed due to faculty retirement and reassignment.

Water, Conservation, and Exurban Development in Semiarid Grasslands of Southwestern North America -- Impacts on Biodiversity and Ecosystem Services

Waite R. Osterkamp, U.S. Geological Survey
Joe E. Marlow, Sonoran Institute

Research personnel of the U. S. Geological Survey (USGS) have had a long-standing collaboration with universities and other nonprofit organizations to study and protect native grasslands of the American Southwest. Waite Osterkamp, of the USGS National Research Program and Board Member of The Research Ranch Foundation (TRRF), and Joe Marlow, of the Sonoran Institute (SI), have written "Water, Conservation, and Exurban Development in Semiarid Grasslands of Southwestern North America -- Impacts on Biodiversity and Ecosystem Services". The document describes recent workshops conducted by TRRF and SI, and proposes innovative approaches to grasslands research. Feedback on the intended research is welcome, and participation is encouraged.
