Bears in Yellowstone National Park and visitors who watch bears cost money, both in terms of the park's approach to bear management, and its approach to "bear jams" on the park's roads.

Mountain goats are spectacular animals, even iconic in places such as Glacier National Park, but they can cause problems in parks where they don't belong. At Olympic National Park, where a 1920s era introduction project brought non-native goats into the landscape, officials are embarking on a management plan for how to deal with the animals. Adding weight to the need for such a plan was the fatal goring of a hiker in the park four years ago.

In what would be a milestone for the California condor recovery program, biologists believe a pair of the large birds has hatched a chick high in the cliffs of Zion National Park.
The moose population at Voyageurs National Park in Minnesota seems to be holding its own, according to a recent survey conducted by park biologists. While the herd isn't growning, moose mortality rates in Voyageurs are about half of that found elsewhere in northeastern Minnesota, officials say.
Rum Island on Long Pond in Acadia National Park in Maine will be closed to the public through mid-July so you won't ruffle the feathers of loons that nest there.
Across the National Park System, groups are constantly work to improve the plight of both animals and human visitors. At Yellowstone National Park, one aspect of that effort is to install bear-proof boxes that will keep bears and campers out of each other's way. But as of today, more than 1,000 bear boxes are still needed, and the Yellowstone Park Foundation is trying to raise the money needed to close that gap.
A young grizzly bear apparently fell to its death in Glacier National Park, where it was found on the Going-to-the-Sun Road by maintenance workers.
