Canada lynx navigate spruce beetle-impacted forests

Science Spotlights Posted on: August 11, 2020
Canada lynx depend on boreal and subalpine forests that have been structured by natural disturbances for millennia.  The management conundrum is how to salvage beetle-killed trees, while also conserving this iconic species.  We instrumented Canada lynx with GPS collars to learn how they used beetle-impacted forests.  Our research informed how to balance timber salvage with species conservation.

A specialized forest carnivore navigates landscape-level disturbance: Canada lynx in spruce-beetle impacted forests

Publications Posted on: July 29, 2020
Canada lynx (Lynx canadensis) occupy cold wet forests (boreal and subalpine forest) that were structured by natural disturbance processes for millennia. In the Southern Rocky Mountains, at the species’ southern range periphery, Canada lynx habitat has been recently impacted by large-scale disturbance from spruce beetles (Dendroctonus rufipennis).

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.

Predicting forest understory habitat for Canada lynx using LIDAR data

Publications Posted on: May 15, 2020
Canada lynx (Lynx canadensis) is a federally threatened species in the contiguous United States. Within National Forests covered by the Northern Rockies Lynx Management Direction, Federal land managers must consider the effect of management activities on Canada lynx habitat. A common method to assess Canada lynx habitat used by the U.S. Forest Service is to measure horizontal cover using a cover board.

Circadian activity patterns of Canada lynx in western Montana

Publications Posted on: March 04, 2020
We recorded activity data for 6 male and 5 female lynx in winter and 3 male and 6 female lynx during summer in western Montana, USA, using motion-sensitive radiocollars. Lynx diel activity appeared to vary by sex, season, and reproductive status. During summer, male lynx exhibited a crepuscular activity pattern, whereas females with kittens remained active throughout the photoperiod.

Precommercial thinning reduces snowshoe hare abundance in the short term

Publications Posted on: March 04, 2020
Management of young forests is not often considered in conservation plans, but young forests provide habitat for some species of conservation concern. Snowshoe hares (Lepus americanus), critical prey of forest carnivores including the United States federally threatened Canada lynx (Lynx canadensis), can be abundant in young montane and subalpine forests with densely spaced saplings and shrub cover.

Functional responses in habitat selection: Clarifying hypotheses and interpretations

Publications Posted on: October 02, 2019
A fundamental challenge in habitat ecology and management is understanding the mechanisms generating animal distributions. Studies of habitat selection provide a lens into such mechanisms, but are often limited by unrealistic assumptions. For example, most studies assume that habitat selection is constant with respect to the availability of resources, such that habitat use remains proportional to availability.

Management of forests and forest carnivores: Relating landscape mosaics to habitat quality of Canada lynx at their range periphery

Publications Posted on: October 02, 2019
Connecting forest management with the conservation of forest-associated animals requires an understanding of habitat quality, as well as identifying long-term silvicultural strategies that align with high quality habitat. It is, therefore, essential to characterize the spatio-temporal dimensions of habitat quality.

Sharing the same slope: Behavioral responses of a threatened mesocarnivore to motorized and non-motorized winter recreation

Publications Posted on: October 04, 2018
Winter recreation is a widely popular activity and is expected to increase due to changes in recreation technology and human population growth. Wildlife are frequently negatively impacted by winter recreation, however, through displacement from habitat, alteration of activity patterns, or changes in movement behavior.

Using environmental features to model highway crossing behavior of Canada lynx in the Southern Rocky Mountains

Publications Posted on: January 10, 2017
Carnivores are particularly sensitive to reductions in population connectivity caused by human disturbance and habitat fragmentation. Permeability of transportation corridors to carnivore movements is central to species conservation given the large spatial extent of transportation networks and the high mobility of many carnivore species.
