pubs.usgs.gov — A new tool provides land managers with a predictive model for mapping the potential distribution of desert tortoise habitat and to evaluate different land-use issues the tortoises face at a landscape scale. The model incorporates an extensive amount of field data for desert tortoises, as well as environmental data related to landscape attributes, More...

www.esajournals.org — Periodic wildfire maintains the integrity and species composition of many ecosystems, including the Mediterranean-climate shrublands of California. However, human activities alter natural fire regimes, which can lead to cascading ecological effects. Increased human ignitions at the wildland-urban interface (WUI) have recently gained attention, but More...

www.fort.usgs.gov — Migratory birds face many changes to the landscapes they traverse and the habitats they use. Wind turbines and communications towers, which pose hazards to birds and bats in flight, are being erected or proposed across the United States and offshore. Human activities can also destroy or threaten habitats critical to birds during migratory passage, More...

wfrc.usgs.gov — There are approximately 500,000 abandoned mines in the western US. Collectively, these mines pollute rivers, streams, and western reservoirs with millions of tons of metals annually that degrade aquatic habitat and water used by humans for drinking, recreation, and irrigation. However, there is great potential in decreasing or eliminating the flow More...

www.werc.usgs.gov — The Pacific iguanas of the Fijian and Tongan archipelagos are a biogeographic enigma in that their closest relatives are found only in the New World, separated by 8,000 km of ocean. The Pacific iguanas have been dramatically affected by human activities; two species were eaten to extinction after human arrival in the Pacific some 2,800 years ago. More...

www.nrmsc.usgs.gov — To devise credible strategies for managing human-wildlife conflicts, managers need information about the importance of specific areas to particular species. In the Greater Yellowstone Area, for example, development of low-elevation areas seriously threatens vital ungulate winter ranges, with obvious implications for both ungulates and their More...
