Mention wolves and national parks and most think of Yellowstone National Park right? But Voyageurs National Park in Minnesota has a growing wolf population.

A group that long has questioned how the National Park Service manages bison at Yellowstone National Park wants to see tribal entities given co-stewardship of the iconic animals along with seeing their numbers rise 10-fold to 50,000 in the Greater Yellowstone Ecosystem.

A long-running gap in reviews into the health of the endangered Florida panther population has prompted a petition to the U.S. Fish and Wildlife Service that it produce the report as required.

Visitors to Yellowstone National Park are taking a toll on the park's wildlife, where in recent days two black bears have been killed by motorists, an elk and a bison were also hit by vehicles, a newborn elk calf was picked up by motorists concerned for its fate, and a bison calf had to be put down after a visitor tried to help it out of the Lamar River so it could catch up with its mother.
