Grizzlies

Grizzlies, Grizzly Bears of Denali National Park

Grizzly Bears are majestic wild creatures. Grizzlies are a naturally regulated wildlife population in Denali National Park and Preserve. The park’s bear population has been studied for over twenty years–one of the longest running studies of naturally regulated grizzly bears. The Grizzlies are monitored visually and by observing radio-instrumented (tagged) individuals. The population trend determined from the calculated vital rates indicates that the Grizzly Bear population is likely to be decreasing slightly.

In the 20 years of this study or in concurrent studies in the park, are you seeing a change in vegetation as part of climate change? Shrubs at higher elevations, different shrubs in some drainages, new plant species within forage ranges?

Are you seeing any change in length of denning periods or interruptions during denning that may be attributable to climate change?

Thank you.

Nita,
Yes, we are documenting vegetation changes mostly in terms of shrubs at higher elevations, no new plant species yet. No changes in denning length that we can detect so far and no interruptions during denning.
