Roundup of Nearly 300 Yellowstone National Park Bison, With Some Destined For Slaughter, Draws Condemnation
Hopes for tolerance of migratory Yellowstone National Park bison by Montana officials seemed to unravel this week, as the park's tortuous winter drove hundreds of bison out of the park. While they were quickly rounded up, some appear headed to slaughter.

They collar moose at Voyageurs National Park. And by doing this, biologists and ecologists can learn not only how the animals are coping with warming weather related to climate change, but how different land-management techniques affect them.
In the grand scheme of wildlife management, 25 Yellowstone National Park bison are not that big of a deal, not when the park's herds are pushing 4,000 animals. But if 25 are allowed to freely roam into Montana on land just north of Mammoth Hot Springs, they could begin laying the foundation for much greater tolerance of bison in Montana.
Seasonal Closure of Paurotis Pond At Everglades National Park Implemented to Help Nesting Wood Storks
With the "dry season' having arrived, the birding at Everglades National Park is exceptional. But it comes with some restrictions, such as the annual closure of Paurotis Pond and its surrounding area to give nesting wood storks and other species some protection.

More than a decade after non-native lake trout were discovered in Yellowstone Lake, the battle to beat down the population of those voracious fish continues. While gill-netting long has been used to cull the lake trout, Yellowstone National Park officials want to increase those operations to help native cutthroat trout survive the onslaught of the bigger fish.
Humpback whales are a big attraction for visitors to a number of NPS sites, and seeing a whale from a boat or the shoreline is a memorable experience. Now a non-profit group's website lets you hear the haunting songs of the humpbacks as they begin arriving in Hawaiian waters for their annual migration.

While the potential exists for the National Park Service's preferred off-road vehicle plan for Cape Hatteras National Seashore to be detrimental to piping plovers, sea turtles, and seabeach amaranth, U.S. Fish and Wildlife Service officials believe the plan will be at least minimally helpful to all three in the long-run.
National Park Service Establishing Protocols For Dealing With White-Nose Syndrome in Bat Populations
It looks somewhat like a dusting of confectioner's sugar, but the white coating that is showing up on more and more noses and wings of bats is the signature of a dire fungal disease that threatens to decimate bat colonies across the country.
As Winter Settles In, Seasonal Migrations Lend Interest to Wildlife Watching in America's National Parks
Seasonal migrations offer special opportunities to see wildlife herding and flocking, leaving, passing through, and arriving in our national parks.
The latest of a running series of reports outlining how climate change could reshape national parks portrays economic and environmental impacts lashing at Acadia National Park and its surrounding communities. While the report's authors hope to catch the attention of Congress, they acknowledge that a groundswell of public concern might be necessary to convince politicians to act.
Another dozen black-footed ferrets now call Wind Cave National Park in South Dakota home, the result of plague preventing their release elsewhere in the West.
A big decision at Point Reyes National Seashore could strike at the core values of our national parks.

While state and federal authorities are developing a plan of attack for dealing with white-nose syndrome in bat populations, a non-profit organization is criticizing the federal government for moving too slowly on this growing problem.
One of the most comforting things you can find in your national park campground that lies within bear country is a metal box into which you can store your foodstuffs and cooking gear when you're not using it. And recent work in Grand Teton National Park means there's going to be quite a few more comfortable campers enjoying the park.

But for many who call the Outer Banks of North Carolina home, that's how they view sea turtle eggs, as threats to their enjoyment of Cape Hatteras National Seashore and, for some, even their livelihoods.
It's long been known, and feared, that habitat fragmentation can create biological islands that require heavy human intervention to prevent genetic dead-ends.

All Was Not Lost When Loggerhead Turtle Determined to Nest at Cape Hatteras National Seashore Was Run Over
Photographs of a female loggerhead turtle that was run over on Cape Hatteras National Seashore back in June told a pretty grim story. Amazingly, though, after seashore biologists placed 92 of her eggs in a nest cavity, six continued their incubation and hatched.
