Prior to removal of pest species from an area, resource managers must determine if re-immigration from another population is possible. Voles inhabiting Saddle Rock on the southern Oregon coast are suspected to be partially responsible for declines in the Leach's storm petrel colony on the island. The island is very close to the mainland, and it is potentially accessible during below-average low tides. USGS scientists Mark Miller and Susan Haig and colleagues used genetic techniques to assess island vole population connectivity.

Multiple large scale solar, wind, and geothermal energy development projects are currently proposed across the Mojave and Sonoran deserts of the southwestern United States, and these development needs are likely to continue or increase into the future. Agencies tasked with managing biological resources throughout this region must understand the potential impacts of these renewable energy plants and associated infrastructure (e.g., transmission corridors, substations, access roads, etc.) in order to select appropriate development sites and to mitigate for anticipated effects. One of the major concerns of this new green energy initiative is determining how future development will impact wildlife movement, population...
