Return of the Yellowstone Grizzly Bear
Detailed Description
Yellowstone grizzly bears inhabit federal, state, tribal, and private lands, and long-term research requires careful coordination across governmental levels. The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 and today’s members include representatives from the U.S. Geological Survey, National Park Service, U.S. Fish and Wildlife Service, U.S. Forest Service, the Eastern Shoshone and Northern Arapaho Tribal Fish and Game Department, and the States of Idaho, Montana, and Wyoming. This interagency approach ensures consistency in data collection and allows for combining limited resources to address information needs throughout the GYE.
The study team, now led by the U.S. Geological Survey, has conducted research on this the Yellowstone grizzly bear for over 40 years, perhaps the largest collection of scientific information on any bear species in the world. This video highlights what decades of science tell us about this charismatic species and its conservation.
The USGS provides the unbiased science needed to manage America’s natural resources and to help endangered and threatened species recover.
The USGS led Interagency Grizzly Bear Study Team is part of the USGS Northern Rocky Mountain Science Center. The center is part of the Northwest Region of the USGS. Scientists from the Center work in the northern Rocky Mountains of the United States and across the U.S. Many of their scientists work throughout the world on issues as diverse as global climate change, aquatic ecology, wildlife diseases, bison ecology, and large carnivores.

Grizzly bear with cubs rubbing on a bridge
Bears rub on many objects other than trees. This clip shows a grizzly bear with two yearlings rubbing on a wooden bridge on a decommissioned forest road. Barbed wire is attached to the wooden bridge beams and the bear rub tree next to the bridge to collect bear hair. This footage is still photos from a remote camera that have been stitched together in sequence.

Status of Grizzly Bears in Northwest Montana
The size and distribution of grizzly bear populations in northwest Montana has just been released by the USGS, so research biologist Kate Kendall bring us up to speed on the findings.

Grizzly Bear and Cub in Bear Hair Trap
Grizzly bear and her cub visit a bear hair trap in Glacier National Park. The bear leaves hair samples snagged on the barbed wire as it enters and exits the site. Both bears vigorously rub in the lure pile which is a pile forest debris that had a liquid scent lure poured on it.

Grizzly Bear Rubbing Tree and Log
This is two video clips captured at the same site from two different angles. The rub trees are on one side of the trail and the excavated log is on the other side. Bears that rub on one or more of the trees often visit the log as well.

Grizzly Bear with Cubs Charges Wolf
A wolf feeds on a road-killed elk carcass in the morning. A grizzly bear with two cubs feeds on the carcass in the evening. A grizzly bear will chuff and pop its jaw when it feels threatened. Sometimes it will also charge at the threat, usually veering off or stopping short -- a bluff charge.

Grizzly Bear Rubbing Tree
Grizzly bear sniffs and rubs on trees regularly used by bears in Glacier National Park then visits a log off screen and returns to the trees to rub again.

Dancing Grizzly
Grizzly bear vigorously rubbing on a natural marking tree in Glacier NP, Montana. Rubbing is a form of chemical communication. DNA analysis of hair collected from natural rub trees is used to identify individual bears and census the population.

Grizzly Bear Claws and Licks Camera
Grizzly bear paws and licks one of our remote cameras and eventually pushes it off the tree. The camera container had a screw top lid that moves as the bear paws at it; the camera was not damaged (Make sure you have your sound on for this).

Grizzly Under Barbed Wire
Grizzly bear goes under barbed wire into a hair snag station, sniffs scent lure pile, and leaves. DNA analysis of hair deposited on the barbs identifies the bear for a study of bear population size.

Big Grizzly at Hair Trap
Grizzly bear climbs over barbed wire at a hair snag station near Glacier NP, Montana. DNA analysis of bear hair is used to identify individuals as part of study to determine the size of the bear population.
