Pacific fisher trying to grab a chicken dinner from the bait box

USGS scientists are documenting the distribution of three mid-sized mammalian carnivores – or mesocarnivores –in the Klamath Network Parks using remote cameras and hair snares. Little is known about the status of Pacific fishers, Pacific martens, and Sierra Nevada red foxes living in the Klamath Network, which include Crater Lake National Park, Lassen Volcanic National Park, Lava Beds National Monument, Oregon Caves National Monument, and Whiskeytown National Recreation Area. The results will provide baseline information on mesocarnivore distribution, allow researchers to determine probability of their occurrence, and help assess whether visitor-use patterns influence species’ distribution.
