Revision of Special Regulation for the Central Idaho and Yellowstone Area Nonessential Experimental Populations of Gray Wolves in the Northern Rocky Mountains

We, the U.S. Fish and Wildlife Service (Service), have revised the 2005 special rule for the central Idaho and Yellowstone area nonessential experimental population (NEP) of the gray wolf (Canis lupus) in the northern Rocky Mountains. Specifically, we have modified the definition of "unacceptable impact" to wild ungulate populations so that States and Tribes with Service-approved post-delisting wolf management plans (hereafter, referred to as wolf management plans) can better address the impacts of a recovered wolf population on ungulate herds and populations while wolves remain listed. We made other minor revisions to clarify the requirements and processes for submission of proposals to control wolves for unacceptable ungulate impacts. We also modified the 2005 special rule to allow persons in States or on Tribal lands with wolf management plans to take wolves that are in the act of attacking their stock animals or dogs. All other provisions of the special rule remain unchanged. As under the existing terms of the 2005 special rule, these modifications do not apply to States or Tribes without wolf management plans or to wolves outside the Yellowstone or central Idaho NEP areas.
