A Summer of Humans vs. Grizzlies - NYTimes.com

There are three times as many grizzlies in Yellowstone as there were in the 1970s, and in the wildlands around Glacier National Park, the largest population in the nation, the number of bears has grown from 250 to around 900 since the grizzly was placed under protection 1975. Grizzlies are being seen in places they haven’t been seen in decades, and wildlife officials are considering taking the bear off the endangered species list around Glacier in the next few years.
