Managing forests and forest carnivores: Canada lynx and forest mosaics

Science Spotlights Posted on: September 07, 2018
The management of Canada lynx habitat is an issue that has generated much debate and litigation across the Northern (Montana, Idaho) and Southern (Colorado, Wyoming) Rocky Mountains. This species depends almost exclusively on snowshoe hare for food during winter, and this prey species is sensitive to changes in forest composition and structure. Research conducted by scientists at the Rocky Mountain Research Station, in collaboration with universities and local forest managers, is central in resolving management impasses by learning how changes in forest structure and composition can be implemented in ways that enhance the ability of Canada lynx to produce kittens.  

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.

Canada lynx are persisting in spruce-beetle impacted forests

Science Spotlights Posted on: August 25, 2016
Spruce-bark beetles impacted about 480,000 acres of spruce-fir forests in southern Colorado and are spreading at the rate of 100,000 acres annually.  A central question is how to salvage for timber production insect-impacted forests in ways consistent with the management and conservation of Canada lynx, a federally-listed species.

A longevity record for Canada lynx, Lynx canadensis, in western Montana

Publications Posted on: January 22, 2016
The Canada lynx (Lynx canadensis) was listed as a threatened species under the Endangered Species Act (USDI Fish and Wildlife Service 2000) in 2000 and is a species of conservation concern in the United States. New insights into the basic demography of southern lynx populations are needed.

Movements of a male Canada lynx crossing the greater Yellowstone Area, including highways

Publications Posted on: January 22, 2016
From 1999-2001, a male Canada lynx engaged in yearly exploratory movements across the greater Yellowstone area including the Teton Wilderness Area and Yellowstone National Park. For three consecutive summers, the lynx traversed a similar path in a northwesterly direction from the animal’s home range in the Wyoming Range near Big Piney, Wyoming, to as far as the Henry’s Lake Mountains, west of West Yellowstone, Montana.

Conservation challenges of managing lynx

Publications Posted on: January 22, 2016
Yellowstone National Park is hallowed ground when it comes to wildlife in America. The very word “Yellowstone” conjures up images of grizzly bears digging tubers, bands of elk dotting the landscape, and gray wolves pursuing elk along the Lamar River. However, Yellowstone also provides habitat to one of the rarest cats in the continental United States: the Canada lynx (Lynx canadensis).

A snow-tracking protocol used to delineate local lynx, Lynx canadensis, distributions

Publications Posted on: January 22, 2016
Determining Canada Lynx (Lynx canadensis) distribution is an important management need, especially at the southern extent of the species range where it is listed as threatened under the U. S. Endangered Species Act. We describe a systematic snowtrack based sampling framework that provides reliable distribution data for Canada Lynx. We used computer simulations to evaluate protocol efficacy.

An effective box trap for capturing lynx

Publications Posted on: January 22, 2016
We designed a box trap for capturing lynx (Lynx lynx) that is lightweight, safe, effective, and less expensive than many commercial models. It can be constructed in approximately 3-4 hours from readily available materials. We used this trap to capture 40 lynx 89 times (96% of lynx entering traps) and observed no trapping related injuries.

Serologic survey for viral and bacterial infections in western populations of Canada Lynx (Lynx canadensis)

Publications Posted on: January 22, 2016
A serologic survey for exposure to pathogens in Canada lynx (Lynx canadensis) in western North America was conducted. Samples from 215 lynx from six study areas were tested for antibodies to feline parvovirus (FPV), feline coronavirus, canine distemper virus, feline calicivirus, feline herpesvirus, Yersinia pestis, and Francisella tularensis. A subset of samples was tested for feline immunodeficiency virus; all were negative.
