Fisher population continues to decline across Superior National Forest
From the “Inland Empire” near the shores of Deer Yard Lake to the end of the Gunflint Trail, fishers area beloved animal of the North Woods.
Fisher populations in northern Minnesota have dropped to about 7,000 from a high of 16,000 in the year 2000.
The decline of the population led to a recent study to evaluate whether den boxes could be a valuable management tool to improve fisher habitat and balance wildlife needs with the forest industry. It is part of a larger effort to understand what factors have caused the recent fisher population decline and provide management solutions to boost fishers in Minnesota, according to Michael Joyce, a wildlife biologist at the Natural Resources Research Institute in Duluth.
