USDA Forest Service Roadless Areas: Potential Biodiversity Conservation Reserves Ecology and Society
Loucks, Colby; World Wildlife Fund; colby.loucks@wwfus.org; Brown, Nicholas; NatureServe; nick_brown@natureserve.org; Loucks, Andrea; Pinchot Institute; andreabedell@pinchot.org; Cesareo, Kerry; World Wildlife Fund; kerry.cesareo@wwfus.org.
In January 2001, approximately 23 x 106 ha of land in the U.S. National Forest System were slated to remain roadless and protected from timber extraction under the Final Roadless Conservation Rule. We examined the potential contributions of these areas to the conservation of biodiversity. Using GIS, we analyzed the concordance of inventoried roadless areas (IRAs) with ecoregion-scale biological importance and endangered and imperiled species distributions on a scale of 1:24,000. We found that more than 25% of IRAs are located in globally or regionally outstanding ecoregions and that 77% of inventoried roadless areas have the potential to conserve threatened, endangered, or imperiled species. IRAs would increase the conservation reserve network...

ENVIRONMENTAL EFFECTS OF AGRICULTURAL LAND-USE CHANGE: THE ROLE OF ECONOMICS AND POLICY AgEcon
Lubowski, Ruben N.; Bucholtz, Shawn; Claassen, Roger; Roberts, Michael J.; Cooper, Joseph C.; Gueorguieva, Anna; Johansson, Robert C..
This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity. If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced changes in land use could have production effects that are smaller-and environmental impacts that are greater-than anticipated. To illustrate this possibility, this report examines environmental outcomes stemming from landuse conversion caused by two agricultural programs that others have identified as potentially having important influences on land use and environmental quality: Federal crop insurance subsidies and the Conservation Reserve Program (CRP), the Nation's...
