In 1979 several breeding pairs of moose were brought to Colorado's North Park. Now the moose numbers are close to two thousand. The population has spread across the state, beyond the continental divide, in 3 different areas of Rocky Mountain National Park.

It is unknown how they affect the park as there has not been a study to address this. With no natural predators and a growing number, more hunters apply for moose permits. More than 14,000 hunters applied last year. About 85 moose are killed annually, from the Denverchannel.com [2].
