Regional Themes

California's geography is unlike any other state. From the Mojave Desert in the southeast, to the high mountain peaks and forests, climate and organisms interact with these ecosystems in special ways. Several major topics are of special concern to California residents and visitors. Visit the pages below to find out more about these topics.

The U.S. Department of Energy, the Bureau of Land Management, the U.S. Forest Service, and the Department of Defense prepared a Programmatic Environmental Impact Statement (PEIS) to evaluate issues associated with the designation of energy corridors on federal lands in eleven Western states. The Draft PEIS was issued in Fall 2007 and the Final West-wide Energy Corridor Programmatic EIS was made available in Fall 2008.

Visit the West-wide Energy Corridor Programmatic EIS Information Center for more information about the PEIS, Record of Decision, and Final PEIS maps of energy corridors. To find out about potential designation of energy corridors in 37 eastern states, and in Hawaii and Alaska, visit the East-wide Energy Corridor Programmatic EIS Information Center.
