Biologists Study Booming Moose Population at Rocky Mountain NP

More moose means more stress on willows, which has big implications for the park ecosystem.

With more moose roaming Rocky Mountain National Park–30 to 50 on the west side alone–scientists are now looking more closely at the population’s impact on the park’s riparian ecosystem by fitting 40 moose with tracking collars. The growing population is affecting willow vegetation, which in turn affects soil and water quality.
