Xanterra Parks & Resorts will donate part of the proceeds from your purchase of this plush wolf to the Yellowstone Park Foundation's Wolf Fund. The gray wolf was reintroduced to Yellowstone National Park in 1995, after a six-decade absence. Today, the Wolf Fund pays for monitoring and tracking Yellowstone's wolves, and for crucial research studies. These efforts help ensure the long-term conservation of the wild wolves in Yellowstone.
