Yellowstone's Ecosystem Is In Good Health

Posted: Updated:
YELLOWSTONE NATIONAL PARK -

Yellowstone National Park's ecosystem is in good health according to the park's latest "Natural Resource Vital Signs" report.

Park officials say wildlife populations in Yellowstone have been steady.

In fact, animals such as bison are on the rise with nearly 5000 bison logged in Yellowstone.

But the park is in a long term drought.

Wildlife officials say they are just learning the effects the drought has on wildlife.

"In terms of forage availability for elk and other grazers in the park it is reasonable to expect maybe a reduced level of forage," said David Hallac, Chief of Resource Management and Science.

The average low temperature in Yellowstone has gone up nearly 4.9 degrees since 1989.
