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.

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/

WGSC geophysicist interviewed about recent quake in Los Angeles

Scientists say Monday’s magnitude 4.4 earthquake in Southern California, and last week’s quakes near the North Coast were simply business as usual in seismically-active California.

“The pattern that we’re seeing now is no different than what we had two or three weeks ago,” said Dr. Gerald Bawden, a geophysicist with the US Geological Survey in Sacramento.  “It just happened to be some were a little bit larger…or happened to be a little bit shallower.”

A larger concern than the recent quake activity, is the lack of activity on major fault lines that have been quiet for many years.

According to Dr. Bawden, a magnitude 6.5 or larger quake is likely on the Hayward fault in the Bay Area within the next 25 years.

“One standard deviation says 65 percent chance,” Dr. Bawden said.
