Ten papers presented as plenary talks at the conference, "Wilderness Science in a Time of Change," are included.

An ecological basis for ecosystem management

Publications Posted on: May 12, 2016
Guiding principles based on conservation biology are applied in assessing ecosystem needs. Ecosystem, economic, and social needs are integrated in a decision model in which the guiding principles are used as a primary filter for evaluating proposed actions.

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.

Chapter 1: A conservation assessment framework for forest carnivores.

Publications Posted on: May 12, 2016
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.

Research on ferruginous hawks in Wyoming

Over the past decade and a half, raptors nesting in prairie ecosystems have been subject to sharp increases in nearby energy development activity. From 2000 to 2006, the number of oil wells in Wyoming increased by 73 percent, and the number of natural gas wells by 318 percent. The management of avian species that depend on sage-steppe ecosystems is an important emerging issue across the western United States, in part due to this increased energy development.

Network theory and sage-grouse management

Documents and Media Posted on: July 15, 2015
The University of Montana and the USFS Rocky Mountain Research Station are advancing the use of network theory within a conservation genetics framework to model genetic population networks for greater sage-grouse.Document Type: Briefing Papers

Canada lynx living in spruce beetle impacted forests

Projects Posted on: July 13, 2015
Canada lynx, and their primary prey snowshoe hares, live in high-elevation spruce-fir forests, which are increasingly modified by spruce-bark beetle outbreaks. The goal of our research is to combine lynx use of insect-impacted forests with measures of forest condition.  Our results will inform forest prescriptions that facilitate timber-salvage and lynx conservation.

Tracking Canada lynx in insect-impacted forests

Media Gallery Posted on: July 13, 2015
Canada lynx, and their primary prey snowshoe hares, live in high-elevation spruce-fir forests, which are increasingly modified by spruce-bark beetle outbreaks.  One important management question is how the timber from these insect-impacted forests can be salvaged in ways that also facilitate lynx conservation.  This issue is of particular concern since climate change is expected to increase the severity of insect-related disturbance in conifer forests.
