An agreement reached by officials from the Interior Department and the state of Wyoming, if allowed to stand, would make Yellowstone National Park a sanctuary for wolves. Most elsewhere in the state the animals could be shot on sight under the plan.

With grizzly bears and people coming closer and closer to one another in the front country of Grand Teton National Park, officials have refined their guidelines as to how close people can be to wildlife. The need for the revisions arose as more and more visitors took to the roofs of their vehicles to photograph bears and, in at least two instances, bears took exception and charged the vehicles, according to park officials.

In an unusual, but apparently not unprecedented, move in wildlife behavior, two grizzly sows in Grand Teton National Park have swapped a cub. Making the swap even more curious is that the sows involved are themselves mother and daughter.

Whitebark pine trees, a foundation species that grows high in the upper reaches of parks such as Yellowstone, Grand Teton, Glacier, Yosemite, and Kings Canyon, is in need of Endangered Species Act protection from climate change, according to the U.S. Fish and Wildlife Service.
