Fishers and martens and lynx, oh my! Multiregional, goal efficient monitoring of mesocarnivores

Publications Posted on: February 13, 2019
Mesocarnivores, fisher, marten, lynx, wolverine and others, are an important part of forest ecosystems, but they are often difficult to detect, occur in low densities, and have large home ranges. This makes it difficult for biologists to estimate the number of individuals in a specific species in a particular ecosystem. Publication: RMRS-GTR-388

Multispecies mesocarnivore monitoring: USDA Forest Service multiregional monitoring approach

Publications Posted on: December 14, 2018
Small- to mid-sized forest carnivores, also known as mesocarnivores, are an important part of the animal community within national forests.

Ski areas affect Pacific marten movement, habitat use, and density

Publications Posted on: August 24, 2017
Alpine ski recreation is one of the most popular outdoor winter sports globally but often involves habitat modification and dense human activity, both of which can harm wildlife. We investigated the effects of ski area development and winter recreation activities on movement, occupancy, and density of Pacific martens (Martes caurina) in the Lake Tahoe region of California and Nevada, USA by comparing 3 ski and 3 control study areas.

Activity patterns of American martens, fishers, snowshoe hares, and red squirrels in westcentral Montana

Publications Posted on: December 15, 2015
We investigated winter activity patterns of American Martens, Martes americana, Snowshoe Hares, Lepus americanus, and Red Squirrels, Tamiasciurus hudsonicus, in westcentral Montana between November 1994 and March 1995 using dual-sensor remote cameras.

Characteristics of American marten den sites in Wyoming

Publications Posted on: December 15, 2015
We examined characteristics of den structures and den sites used by female American marten (Martes americana) for natal and maternal dens in the Sierra Madre Range, Wyoming. During 1988-95, we located 18 natal dens (parturition sites) and 97 maternal dens (sites where kits were present exclusive of parturition) used by 10 female marten.

Comparison of proposed survey procedures for detection of forest carnivores

Publications Posted on: December 15, 2015
American marten (Martes americana), fisher (M. pennanti), wolverine (Gulo gulo), and lynx (Lynx lynx) are forest carnivores believed threatened by disturbance of late-successional forests. To manage forested ecosystems for these species, effective methods for their detection must be available. Recently, the U.S.

Effects of snow on fisher and marten distributions in Idaho

Publications Posted on: October 01, 2013
Studies have suggested that deep snow may limit fisher (Martes pennanti) distribution, and that fisher populations may in turn limit marten (Martes americana) distribution. We tested these hypotheses in the Northern Rocky Mountains of Idaho, a region which differs from previous study areas in its climate and relative fisher and marten abundance, but in which very little is known about their distributions.
