CHEYENNE, Wyo. (AP) — A conservation group is asking the National Park Service to rule that an area between Grand Teton and Yellowstone national parks should be off-limits to wolf hunting. The National Parks Conservation Association on Wednesday filed a petition with the National Park Service asking it to start a formal rulemaking process.

The association wants the federal agency to find that wolf-hunting shouldn't be allowed in the 24,000-acre John D. Rockefeller Jr. Memorial Parkway. Wyoming officials say they haven't yet reviewed the group's petition.

However, the state game and fish department has stated in its wolf hunting regulations that the state has authority over the Parkway area. Wyoming took over wolf management from the federal government late last year and held an organized wolf hunt in areas adjoining the Parkway.
