Layers: Description: A map service, available on the www, that depicts the Inventoried Roadless Areas that were used in the Final Environmental Impact Statement (EIS) for the 2001 Roadless Area Conservation Rule. The EIS analysis team used this spatial data to assess the impacts of roadless area alternatives on Forest Service policies, use of the National Forests, and the surrounding environment. It was used for analysis in combination with national characterization layers, such as ambient human population, forest mortality risk to insects and diseases, current land cover types, and others. The data includes the entire lower 48 states and Alaska at a coarse resolution. The public also had a need to know where IRAs were located in their area and across the nation.
