The Western Geographic Science Center conducts research to help communities make decisions about the interaction between people and their environment. We conduct geographic research on the environmental and societal consequences of a changing landscape.

Our projects analyze human / environmental interactions spatially and temporally. Our work is collaborative, involving many partners and linking many different natural science and social science disciplines. Our work is concentrated in the 9 states of the USGS Western Region and is conducted on local and regional scales.

A Change to the Team

Gerald Bwden

USGS geophysicist Gerald Bawden, is beginning a two-year detail with NASA. Serving as a USGS-NASA liaison during his time there, Gerald will also be a program officer in both the Earth Surface and Interior, and the Water and Energy Cycle focus areas, and his contribution to the design of two new satellites will include SWOT: the Surface Water and Ocean Topography mission that will make for the first comprehensive survey of the world’s surface water. The other satellite he’ll be working on is the NI-SAR: the Synthetic Aperture Radar mission that studies natural hazards, the cryosphere, and ecosystems.

Future Scenarios of Impacts to Ecosystem Services on California Rangelands

The 18 million acres of rangelands in the Central Valley of California provide multiple benefits or “ecosystem services” to people—including wildlife habitat, water supply, open space, recreation, and cultural resources. Most of this land is privately owned and managed for livestock production. These rangelands are vulnerable to land-use conversion and climate change. To help resource managers assess the impacts of land-use change and climate change, U.S. Geological Survey scientists and their cooperators developed scenarios to quantify and map changes to three main rangeland ecosystem services—wildlife habitat, water supply, and carbon sequestration. Project results will help prioritize strategies to conserve these rangelands and the ecosystem services that they provide. http://pubs.usgs.gov/fs/2014/3019/

Following a year of powerful flood events in
northeastern Santa Cruz County, there was no lack of
interest in a recent field trip to the Babacomari Ranch
where the Borderlands Restoration Group has been
constructing hundreds of erosion-control structures.

Organized by the Santa Cruz Natural Resource
Conservation District (SCNRCD) and hosted by
Charlie Brophy, who represented the owners of the
Babacomari Ranch, the Oct. 17 event consisted of a
tour for area landholders led by Borderlands
representatives David Seibert and Trevor Hare. The
two have been leading work crews and giving their
expertise in building erosion-control structures on the
ranch and elsewhere in the county.
Hare said the Babacomari Ranch was a key location for
their work because it feeds the Babacomari River and
consequently the San Pedro River system, a top
priority for entities including The Walton Family
Foundation, which bankrolls much of Borderlands’
work... Read full article
