Construction Work To Result In Yellowstone Road Closures After Labor Day
Two sections of Yellowstone’s Grand Loop Road will be closed due to construction after the Labor Day holiday weekend. Travel between some points will involve long detours and significantly longer than normal travel times. More »
Where Are All the Bears?
Bears were once commonly observed along roadsides and within developed areas of Yellowstone National Park (YNP). Bears were attracted to these areas by the availability of human foods in the form of handouts and unsecured camp groceries and garbage. Although having bears readily visible along roadsides and within developed areas was very popular with the park visitors, it was also considered to be the primary cause of an average of 48 bear-inflicted human injuries and 138 bear-caused property damages per year from 1931 through 1969 (Cole 1974).
In 1970, YNP initiated an intensive bear management program with the objectives of restoring the grizzly bear and black bear populations to subsistence on natural forage and reducing bear-inflicted human injuries and bear-caused property damages (Cole 1976, Meagher and Phillips 1983). As part of the bear management program implemented in 1970, regulations prohibiting the hand feeding of bears were strictly enforced, as were regulations requiring that human food be kept secured from bears. In addition, garbage cans were bear-proofed and garbage dumps within and adjacent to the park were closed.
Although bears are less frequently observed along roadsides and within developed areas today than in the past, many people still see bears each year. From 1980-2011 over 40,000 bear sightings have been reported to park managers. Grizzly bears are active primarily during nocturnal (night time) and crepuscular (dawn and dusk) time periods (Schleyer 1983, Harting 1985, Gunther 1991). Look for grizzly bears with a high power spotting scope in open meadows just after sunrise and just before sunset. Grizzly bears are most commonly observed in Lamar Valley, Gardiners Hole, Antelope Creek meadows, Dunraven Pass, Hayden Valley, and in the wet meadows along the East Entrance Road from Fishing Bridge to the East Entrance of the park. Black bears are active primarily during crepuscular and diurnal (daylight) time periods (Mack 1988). Look for black bears in small openings within or near forested areas. Black bears are most commonly observed on the northern portion of the park along the road corridor from Elk Creek to Tower Falls, and from Mammoth Hot Springs north to Indian Creek. Black bears are also commonly observed in the Bechler region in the southwest corner of the park. Spring and early summer are typically the best times to view bears. During years when whitebark pine trees produce abundant cone crops, bears move up into whitebark pine forests in late summer and fall to feed on whitebark pine seeds. Bears are not readily visible when foraging in forested areas. However, if the late summer crop of whitebark pine seeds is poor, bears will remain in lower elevation meadows digging roots and truffles. and scavenging wolf killed ungulate carcasses providing good bear viewing opportunities.
With visitation averaging around 3 to 3.5 million visitors annually, many bears are exposed to frequent encounters with people and traffic. These bears habituate to the presence of people and often tolerate people at distances of only 20-30 yards. Habituated bears are still wild bears and capable of inflicting serious injury or death. For your safety, remain within your vehicle when viewing and photographing roadside habituated bears. Always pull completely off of the road into paved pull-outs when stopping to view bears. Make sure your vehicle is in park and that you engage your emergency brake. Never approach, crowd, or surround bears. Running in the presence of bears may trigger a chase and attack response. Proper viewing and photographing etiquette will help keep both you and roadside habituated bears safe.

Did You Know?
There were no wolves in Yellowstone in 1994. The wolves that were reintroduced in 1995 and 1996 thrived and there are now over 300 of their descendents living in the Greater Yellowstone Area.
