Whether you believe wolves can have an impact on the course of rivers in Yellowstone National Park or not, there is evidence that bears can impact the vegetation of a landscape, simply by eating.
In a stroke of luck, a remote, motion-triggered camera in Yosemite National Park has captured a Sierra Nevada red fox out for a winter's day stroll in what is believed to be the first sighting of the rare carnivore in nearly a century.
“…A country without wolves isn’t really good country, it's incomplete - it doesn’t have its full spirit,” said Yellowstone National Park biologist Doug Smith during an interview last year with NPR’s Snap Judgement, about wolves, specifically about the life and death of a famous Yellowstone wolf, 832F, or 06.
Coastal brown bears can get to be huge animals. With their hankering for salmon, they certainly get a lot of protein to help bulk up. But what about shellfish? Do the bears of Katmai National Park in Alaska relish clams, whether on the half shell or not?
Plans by Yellowstone National Park officials to remove roughly 1,000 bison from the park's herds are drawing criticisms and protests from groups that say the slaughter is unnecessary.
Approved "takings" of grizzly bears in part of the Greater Yellowstone Ecosystem threaten to undercut recovery of the species, according to groups that plan to sue the U.S. Fish and Wildlife Service over the matter.
A female gray wolf, possibly one that has been spotted in recent months on the North Rim of Grand Canyon National Park, has been shot and killed in Utah, according to a group dedicated to the protection of endangered species.
In generations past, survival may have depended on a person's ability to "read sign" in the natural world to secure food, detect the presence of friends or foes, or find the safest route to a destination. Those skills are rarely needed by most of us in today's world, but the ability to sort out what happened by interpreting tracks or other evidence on the ground—or in the snow—can be a fun and sometimes challenging activity.
Christmas is coming a bit late at Theodore Roosevelt National Park in North Dakota. At least if you wanted to be involved in the holiday bird count there.
The excitement surrounding word that a condor chick had been born this year in Zion National Park, the first condor born in southern Utah in decades, has been dashed by word that the chick apparently has died.
They're big, hard to see until the last minute, can do substantial damage to your vehicle, and likely will wind up dead if you run into them. With longer nights having arrived across the National Park System, it's time to drive a little more carefully and slowly so you don't run into wildlife.
With the arrival of chronic wasting disease in Shenandoah National Park deer seemingly imminent, park staff are working on amending its plan for dealing with the disease to allow for the culling of deer to try to limit the spread of the disease.
The possibility that a gray wolf is roaming the North Rim of Grand Canyon National Park has prompted the U.S. Fish and Wildlife Service to quickly approve an effort to capture the animal and test its DNA to confirm whether it is, or is not, a full-blooded gray wolf, not a Mexican wolf and not a hybrid.
Healthy bison herds at Wind Cave National Park in South Dakota are sowing their genes through a program with The Nature Conservancy that operates bison preserves in Missouri, Iowa, Kansas, South Dakota, and Illinois.
Nearly 20 years after gray wolves were returned to Yellowstone National Park, conservationists believe a "disperser" has found its way to the North Rim of Grand Canyon National Park and is looking to carve out a home range.
For years, many conservationists have worried what grizzly bears in the greater Yellowstone ecosystem will eat as changing climate and habitat conditions bring fewer whitebark pine nuts, cutthroat trout and other prime food sources. A recent study offers an answer: almost anything else.
The Cherokee Nation in Oklahoma recently welcomed a herd of bison to its reservation after a four-decade absence. The first herd came from Badlands National Park in South Dakota, and another 10 bison are to be delivered to the tribe from Theodore Roosevelt National Park in North Dakota.
Federal biologists believe elk hunters in Grand Teton National Park and on the National Elk Refuge in the next nine years will kill six more grizzly bears than originally anticipated.
A rabies alert has gone up at Grand Canyon National Park, where a bat with the disease has been found in the Inner Gorge along the Colorado River.
Groups Sue Over U.S. Fish And Wildlife Service's Refusal To Provide Wolverine With Endangered Species Act Protection
Whether climate change is adversely impacting wolverines, something the U.S. Fish and Wildlife Service believes is uncertain, is being challenged by a coalition of conservation groups that is suing the agency to provide Endangered Species Act protection to the small carnivores.
A genetic sampling of more than 300 mountain lions in southern California, including within the Santa Monica Mountains National Recreation Area, shows the big cats lack genetic diversity.
Padre Island National Seashore in Texas is home to one of the largest nestings of rare Kemp's Ridley sea turtles. And it also sees a number of other turtle species throughout the year, as well. And sometimes, when those turtles show up in the winter months, cold snaps can stun them. You can learn how to deal with a stunned turtle by attending a park lecture later this month.
With a small, isolated population of pupfish at Death Valley National Park facing a 30 percent chance of going extinct by 2034, a University of California scientist is suggesting a more aggressive captive-breeding program for the fish.
Yosemite National Park long has had a history of problems between visitors and the park's black bears, but those appear to be a thing of the past. Since 1998, officials note, bear incidents that have generated personal property damage have dropped by 95 percent.
Environmental organizations are claiming a victory over a settlement that will indefinitely close some off-road vehicle trails in Big Cypress National Preserve until officials can complete their Backcountry Access plan.
Fall brings so much to the national parks, with changing colors blanketing the landscapes, visitor loads dropping, and wildlife on the move, both for migration and, for some, the annual rut. And that rut can make wildlife such as elk, moose, and bison unpredictable and especially dangerous to park visitors who wander too close to these big animals.
Gunshots could soon be echoing across the Antietam, Monocacy, and Manassas national battlefields near the nation's capital as National Park Service personnel work to bring down populations of white-tailed deer that are far above numbers that can interfere with natural revegetation on the landscape.
A unique and beautiful area of Great Smoky Mountains National Park is temporarily being closed to visitors in an effort to protect bats that enter caves there.
Wind Cave National Park rangers will be leading tours this month to listen for the bugle of the Rocky Mountain elk. The elk’s high-pitched whistle heralds the arrival of fall and the elk’s mating season.
