Scientists are developing methods to better monitor lynxes and other mesocarnivores across the Rocky Mountain region and beyond.</body></html>

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.

Effects of climate change on wildlife in the Northern Rockies [Chapter 8]

Publications Posted on: September 22, 2017
Few data exist on the direct effects of climatic variability and change on animal species. Therefore, projected climate change effects must be inferred from what is known about habitat characteristics and the autecology of each species.

The importance of data quality for generating reliable distribution models for rare, elusive, and cryptic species

Publications Posted on: June 23, 2017
The availability of spatially referenced environmental data and species occurrence records in online databases enable practitioners to easily generate species distribution models (SDMs) for a broad array of taxa.

Sex-biased dispersal and spatial heterogeneity affect landscape resistance to gene flow in fisher

Publications Posted on: June 22, 2017
Genetic connectivity results from the dispersal and reproduction of individuals across landscapes. Mammalian populations frequently exhibit sex-biased dispersal, but this factor has rarely been addressed in individual-based landscape genetics research. In this study, we evaluate the effects of sexbiased dispersal and landscape heterogeneity on genetic connectivity in a small and isolated population of fisher (Pekania pennanti).

Here today, here tomorrow: Managing forests for fisher habitat in the Northern Rockies

Publications Posted on: August 09, 2016
The fisher is a unique member of the weasel family and a sensitive species in the northern Rockies. They were almost extirpated by trapping in the early twentieth century, but these animals (a mix between a native and introduced population) now inhabit a swath of mesic coniferous forests in Idaho and Montana.

Fisher survey protocol

Rocky Mountain Research Station scientists and their partners established survey protocol for studying the geographic range of fisher in the Rocky Mountains and studying their DNA. Document Type: White Papers

The scientific basis for conserving forest carnivores: American marten, fisher, lynx, and wolverine in the western United States.

Publications Posted on: May 12, 2016
This cooperative effort by USDA Forest Service Research and the National Forest System assesses the state of knowledge related to the conservation status of four forest carnivores in the western United States: American marten, fisher, lynx, and wolverine. The conservation assessment reviews the biology and ecology of these species. It also discusses management considerations stemming from what is known and identifies information needed.

Chapter 6: The scientific basis for conserving forest carnivores: considerations for management

Publications Posted on: May 12, 2016
The reviews presented in previous chapters reveal substantial gaps in our knowledge about marten, fisher, lynx, and wolverine. These gaps severely constrain our ability to design reliable conservation strategies. This problem will be explored in depth in Chapter 7. In this chapter, our objective is to discuss management considerations resulting from what we currently know (and don't know) about these four forest carnivores.
