JACKSON, Wyo. (AP) - There have not been any major changes in the number of bighorn sheep, moose and bison populations in the Jackson Hole region, according to wildlife managers.

A recent Wyoming Game and Fish Department aerial survey found that the Jackson moose herd, estimated at 450 animals, was unchanged in size compared with a year ago.

Over that span the Jackson bighorn sheep herd grew slightly to an estimated 425 animals, while the Jackson bison herd went down in size from 691 to 666 total bulls, cows and calves.

Although the Jackson moose herd remains many times smaller than its objective, it’s producing calves at a high rate, Game and Fish wildlife biologist Aly Courtemanch said. The number of young per 100 cows in the herd jumped from 33 to 41 over the last year. Bulls numbered 78 per 100 cows.

“We saw a lot of calves in the Buffalo Valley and we saw a lot of calves in the Gros Ventre as well as southern areas closer to town,” Courtemanch told the Jackson Hole News & Guide (https://bit.ly/1QICFzS). “It’s very promising that we’re seeing good calf numbers out there … it’s just going to take a long time for that to manifest into actual population growth.”

The department would like to count 800 moose on key winter ranges, but this year Courtemanch counted just 164 in those areas. The total moose count in the herd was 213, but that figure was boosted to the estimated 450 animals to account for those not visible.
