June 2008 | Publisher: Other Federal Agency (U.S. Environmental Protection Agency (EPA)) | Format: URL
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.lsc.usgs.gov — This database is the result of a national analysis of land cover pattern. A series of derived maps (different indices, different window sizes) is available. They are proposed for consideration by landscape analysts, as independent variables (e.g., covariates, stratification rules), and as "context" information for finer-scale investigations, for More...

alaska.usgs.gov — Experts believe that catastrophic damage from wildland fire probably will continue to increase across the nation and large fires in recent years have caused concern with land managers as to how to better assess the impacts of fire on landscapes. This is especially true for Alaska's boreal region, where fire frequency, size, and severity appear to More...

alaska.usgs.gov — Biomass burning is one of the most prevalent vehicles of land cover change in the sub-arctic boreal forest, with the frequency of large fire years more than doubling over the past half century across Canada and Alaska. Post-fire succession impacts energy budgets, net ecosystem carbon balance, hydrology, and other ecosystem services, particularly More...

alaska.usgs.gov — This project explores and compares the utility of several remote sensors for mapping height and density characteristics of forests and shrubs in Alaska's arctic tundra and boreal forest at a moderate spatial resolution (250 m). This project aims to explore two key questions: (1) at a moderate spatial resolution (250 m), which sensor is most More...
