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.

Chapter 7: Information needs and a research strategy for conserving forest carnivores

Publications Posted on: May 12, 2016
This forest carnivore conservation assessment summarizes what is known about the biology and ecology of the American marten, fisher, lynx, and wolverine. It is the first step in ascertaining what information we need to develop a scientifically sound strategy for species conservation.

Controversy over managing public lands is neither an unexpected nor recent development. In the 1970's, debate over land management began to focus on the effects of timber management practices on wildlife. This was most evident in the Pacific Northwest where the public was beginning to express strong concerns about the effects of timber harvest in late-successional forests on northern spotted owls and other vertebrates.

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.

Species and habitats at risk

Projects Posted on: October 14, 2015
Land managers require high-quality information on species and habitats at risk to develop effective management strategies. In the absence of information on these species and their habitats, agencies frequently err on the side of the species and make conservative, and often unnecessary, decisions relative to habitat protection. Over 20 years of research by scientists with the Rocky Mountain Research Station are helping address these information needs.

Ancient DNA confirms native Rocky Mountain fisher (Martes pennanti) avoided early 20th century extinction

Publications Posted on: July 15, 2015
Until recently it was assumed that fishers (Martes pennanti) in the Rocky Mountains all were descended from reintroduced stocks. However, a recent study reported that mitochondrial DNA (cytochrome-b and control region) haplotypes of fishers found only in west-central Montana are likely derived from a relic population of fishers that escaped harvests conducted in the early 20th century.

The fisher (Pekania pennanti; formerly known as Martes pennanti) is a North American endemic mustelid with a geographic distribution that spans much of the boreal forests of North America. In the Northern Rocky Mountain (NRM) fishers have been the focus of Endangered Species Act (ESA) listing decisions.

Modeling the effects of dispersal on predicted contemporary and future fisher (Martes pennanti) distribution in the U.S

Publications Posted on: October 01, 2013
Many species at high trophic levels are predicted to be impacted by shifts in habitat associated with climate change. While temperate coniferous forests are predicted to be one of the least affected ecosystems, the impact of shifting habitat on terrestrial carnivores that live within these ecosystems may depend on the dispersal rates of the species and the patchiness of the environment. Much of the Northern U.S.
