Two national groups have filed notice with the federal government that they intend to sue to restore wolves in the western Great Lakes region to the endangered list.
The Humane Society of the United States and The Fund for Animals filed the 60-day notice with the Fish and Wildlife Service Monday, as required under the Endangered Species Act. If the agency doesn't restore federal protections to wolves in Minnesota, Wisconsin and Michigan during that period, they'll ask a court to do it.
Monday marked the opening day of Wisconsin's first wolf hunting season since management of the region's wolf populations returned to the states. Minnesota's season is set to open Nov. 3.
The groups are asking the two states to postpone their wolf seasons until the federal case is resolved.
