Chapter 1: A conservation assessment framework for forest carnivores.

Publications Posted on: June 22, 2020
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.

Demographic fragmentation of a protected wolverine population bisected by a major transportation corridor

Publications Posted on: October 02, 2019
Roads fragment ecosystems around the globe, but the effects of this fragmentation on biodiversity remain poorly understood. Wolverines (Gulo gulo) are snow-dependent carnivores that occur at low densities and they exhibit low genetic diversity at the southern extent of their range where they are snow-limited and fragmented by human development.

Wolverines in winter: Indirect habitat loss and functional responses to backcountry recreation

Publications Posted on: April 05, 2019
Outdoor recreation is increasingly recognized to impact nature and wildlife, yet few studies have examined recreation within large natural landscapes that are critical habitat to some of our most rare and potentially disturbance-sensitive species. Over six winters (2010-2015) and four study areas (> 1.1 million ha) in Idaho,Wyoming, and Montana, we studied the responses of wolverines (Gulo gulo) to backcountry winter recreation.

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.

Sources and patterns of wolverine mortality in western Montana

Publications Posted on: January 19, 2016
We instrumented 36 wolverines (Gulo gulo) on 2 study areas in western Montana and one study area on the Idaho-Montana (USA) border: 14 (9 M, 5 F) on the Pioneer study area, 19 (11 M, 8 F) on the Glacier study area, and 3 (2M, 1 F) on the Clearwater study area. During 2002-2005, harvest from licensed trapping accounted for 9 (6 M, 3 F) of 14 mortalities, including individuals from all 3 study areas.

The efficacy of obtaining genetic-based identifications from putative wolverine snow tracks

Publications Posted on: January 19, 2016
Snow-track surveys to detect rare carnivores require unequivocal species identification because of management and political ramifications associated with the presence of such species. Collecting noninvasive genetic samples from putative wolverine (Gulo gulo) snow tracks is an effective method for providing definitive species identification for use in presence-absence surveys.

Wildlife dispersal ability and landscape connectivity in the northern Rocky Mountains

Science Spotlights Posted on: October 14, 2015
Increasing human populations have fueled urban development and land conversion, causing substantial loss and fragmentation of wildlife habitat. Researchers evaluated conditions for 108 different species across a large portion of the Northern Rockies in order to predict current and potential future patterns of fragmentation, prioritize keystone corridors for protection and enhancement, and identify which species in which places might require habitat restoration or assisted migration.

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.
