Six Ojibwe tribes in Wisconsin are opposing legislation introduced by U.S. Senators Ron Johnson and Tammy Baldwin.
The bill would delist the gray wolf in the western Great Lakes region and Wyoming.
The tribes sent the letter to Washington Wednesday.
It was signed by the Bad River, Lac Courte Oreilles, Lac du Flambeau, Red Cliff, Sokaogon Chippewa, and the St. Croix Chippewa tribes.
The tribes say neither senator discussed the bill with them or how it might affect their federal treaty rights.
An attorney representing the tribes says, “Wisconsin has already demonstrated its inability to properly manage the state’s wolf population and this legislation would ensure another brutal hunt for this keystone species.”
