Canadian bighorn sheep relocated as part of restoration program

Forty bighorn sheep trapped in Alberta, Canada, were released into the Pine Ridge near Harrison on Feb. 9, giving Nebraska a fifth subpopulation of this mammal popular among hunters and wildlife watchers.

The 35 ewes and five rams were trapped on a reclaimed portion of a coal mine at the foot of the Canadian Rockies west of Edmonton, Alberta, on Feb. 7. Seventeen Nebraska Game and Parks Commission staff and two U.S. Department of Agriculture veterinarians traveled to the site last week to assist in the operation and to bring the sheep home.

"We've done a lot of observations, we have looked at the habitat and had some modeling done. Through all of that, we've identified areas that are good sheep habitat but are unoccupied," said Todd Nordeen, the wildlife biologist in charge of the Nebraska Game and Parks Commission's Panhandle operations and head of the agency's bighorn sheep program. "We released these sheep in one of those key areas, which is prime sheep habitat.

"This brings in new genetic traits, and these sheep are big-bodied, so that's going to add some good quality to what we already have. There's a good chance they'll interact with the Fort Robinson sheep."

"The sheep were released on private land with the permission and cooperation from landowners. Their efforts and participation are critically important to the state's natural resources," Nordeen said.

Nebraska's bighorn restoration began with the release of a dozen sheep from South Dakota into a 500-acre enclosure at Fort Robinson State Park near Crawford. Since 2001, 122 sheep from Colorado and Montana have been released in the Pine Ridge east of Crawford and in the Wildcat Hills near Gering.

Bighorns historically were found in Nebraska but were wiped out by disease, habitat loss and sustenance hunting early in the 20th century. Thanks to restoration efforts, the population in both regions now includes about 315 sheep.

The sheep were captured with drop nets set over an area that had been baited with alfalfa for several days. When tripped, the trapping crew, consisting of Game and Parks staff, Alberta Ministry of Sustainable Resource Development staff, private consultants and about 40 volunteers, subdued the sheep, and fitted them with blinders to calm them and hobbles to restrain them. Once removed from the net, veterinarians and Game and Parks biologists took blood, hair, and other samples for disease and DNA testing. Each was fitted with radio or GPS collars so they could be tracked by biologists.

The relocation was funded by the sale and auction of 17 bighorn sheep hunting permits issued in Nebraska since 1998, which has generated more than $800,000. The effort also was supported by the Iowa chapter of the Foundation for North American Wild Sheep, the Wild Sheep Foundation, the Nebraska chapter of Safari Club International, the Western Association of Fish and Wildlife Agencies, the USDA and other conservation groups and volunteers.
