On June 29, 2010, the State of Wyoming issued revised boundaries for its sage-grouse Core Areas. Using the modification criteria described above, the BLM is in the process of reviewing these new Core Areas to determine if and how BLM’s Key Habitat Areas should be modified. This review was not completed in time to allow its incorporation into the Draft RMP and Draft EIS. Table Q-1 compares the acreage of the new sage-grouse Core Area boundaries (Core Areas Version 3) with those of the previous Core Areas (Core Areas Version 2) and BLM’s current Key Habitat Areas. Figure Q-1 shows the differences among these three areas in the Planning Area.
