Wildlife biologists are studying hoary marmots in the high meadows of the North Cascades to determine why their populations are in decline. Researchers with the Cascades Carnivore Project suspect climate change and the shifting range of predators are the culprits.
North Cascades National Park was created fifty years ago after a group of committed hikers and conservationists came together to speak up for wilderness protection in Washington state. Today, the park faces threats from climate change and increasing visitor use -- and will require a new generation of defenders.
