WENATCHEE — Scientists this summer will launch the first large-scale effort to find evidence of grizzly bears in the North Cascades, setting out 75 to 100 hair snags and a few dozen remote cameras.
“We think there’s a few bears wandering around out there, but it’s probably very few,” said Bill Gaines, wildlife biologist for the Okanogan-Wenatchee National Forest. “Certainly we have indications the bears are just north of the Canadian border, and likely would wander back and forth,” he said.
Some attempts were made to document grizzly bears in the mid-1990s, he said, and scientists have used remote cameras to follow up on reported sightings. “In terms of a broad-scale effort, this will be a first,” he said.
