Grizzly bears move into polar bear habitat in Manitoba, Canada
Date:2/23/2010

s horribilis have managed to move from their historic ranges in the Rockies, the Yukon, and Nunavut, probably because of their flexible, mixed diet of berries and meat. The potential gap was navigable, and now some grizzly bears have reached the abundant caribou, moose, fish, and berries found to the south in Canada's Wapusk National Park.

"Although we don't yet know if they are wandering or stayingthe proof will come from an observed den or cubsthese animals will eventually be residents of this national park," says Rockwell. "The Cree elders we talked to feel that now that grizzly bears have found this food source they will be staying."

"A big question is how to deal with these new residents," continues Gormezano. "In Canada, both the polar and grizzly bear are federally listed as species of special concern. In Manitoba, the polar bear is provincially listed as threatened while the prairie population of the grizzly bear is listed as extirpated."
