Although various studies have shown that corn ethanol reduces greenhouse gas (GHG) emissions by displacing fossil fuel use, many of these studies fail to include how land-use history affects the net carbon balance through changes in soil carbon content. We evaluated the effectiveness and economic value of corn and cellulosic ethanol production for reducing net GHG emissions when produced on lands with different land-use histories, comparing these strategies with reductions achieved by set-aside programs such as the Conservation Reserve Program (CRP). Depending on prior land use, our analysis shows that C releases from the soil after planting corn for ethanol may in some cases completely offset C gains attributed...

Ecosystems of the southeastern United States face a large number of threats to their ecological integrity, including loss of habitat, climate change, exotic species invasion, and many more. NatureServe staff, in conjunction with the South Atlantic Landscape Conservation Cooperative (SALCC), have compiled this report in order to better understand how these threats impact ecosystems and the level of impact to these ecosystems, thereby addressing a key information need identified by the SALCC. We have organized the threats according to the first and second level threats classification of the Conservation Measures Partnership (Salafsky et al. 2008). The Conservation Measures Partnership maintains a standard nomenclature...
