When studies started showing that fishers (think big weasel) were declining in northern Minnesota, the DNR and wildlife biologists got concerned.

Michael Joyce, wildlife biologist with the NRRI got a team together, built 100 den boxes out of wood, strapped the 52-lb. boxes to frame packs and schlepped them out into the wilderness in hopes that with safe places to raise their families, fisher populations could start making a comeback.
