March 2009 | Publisher: USGS | Science Center: Western Ecological Research Center (WERC, Sacramento) | Format: .PDF
www.werc.usgs.gov — Fire occurs in many North American ecosystems, and most of these systems are resilient to fires that occur within a broad range of variability in frequency and intensity. In a recent USFS publication (General Technical Report PNW-GTR-779, ), USGS scientist Jon Keeley led a team of scientists from various agencies and academic institutions in More...

www.climatescience.gov — The U.S. Environmental Protection Agency has released a report that can help reduce the potential impact of climate change on estuaries, forests, wetlands, coral reefs, and other sensitive ecosystems. The report identifies strategies to protect the environment as these changes occur. The report finds that climate change can increase the impact of More...

www.nrmsc.usgs.gov — Every winter, government agencies feed ;6000 metric tons (63 106 kg) of hay to elk in the southern Greater Yellowstone Ecosystem (GYE) to limit transmission of Brucella abortus, the causative agent of brucellosis, from elk to cattle. Supplemental feeding, however, is likely to increase the transmission of brucellosis in elk, and may be affected by More...

www.fs.fed.us — USGS scientist Jon Keeley led a team of scientists from various agencies and academic institutions in developing a framework that will inform fire management of ecosystems. This review uses a scientific synthesis to provide an ecological foundation for management of diverse ecosystems. Ecosystem-based management requires different strategies on More...

sbsc.wr.usgs.gov — The Internet Map Server (IMS) visually displays the non-native, invasive plants (weed) occurrences in the current (2003) SWEMP database. An IMS allows you to interactively draw, query, and print maps. The SWEMP IMS was developed from ESRI's ArcIMS presentation product.The Southwest Exotic Plant Information Clearinghouse is a cooperative effort More...

fresc.usgs.gov — Spotted owls are mostly non-migratory, long-lived birds whose populations have declined in mature forests of western North America. They are classified as three subspecies: California, northern, and Mexican. Northern and Mexican spotted owls are listed as threatened under the U.S. Endangered Species Act, and California spotted owls are not. In More...
Publisher: USGS | Science Center: Alaska Science Center (ASC, Anchorage) | Format: URL
alaska.usgs.gov — Mountains are the single dominant physiographic feature throughout most of Alaska. Indeed, mountains are such a defining feature of arctic Alaska and Beringia that they account for over 20 percent of the land area in the entire Holarctic (excluding the Greenland ice sheet). Not surprisingly, the avifauna of the region has been strongly More...
