Spatio-temporal responses of Canada lynx (Lynx canadensis) to silvicultural treatments in the Northern Rockies, U.S.

Publications Posted on: July 10, 2018
Forest managers are often tasked with balancing opposing objectives, such as altering forest structure and conserving forest-dwelling animals. Consequently, to develop holistic strategies managers require information on how forest manipulations influence species of conservation concern, particularly those that are federally threatened or endangered.

The effects of climate change on mammals

Pages Posted on: January 09, 2017
Researchers prepared a synthesis of climate change effects on mammals for the Climate Change Resource Center. Climate change is expected to impact most parts of an ecosystem, and mammals are no exception.

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.

Influence of forest structure on the abundance of snowshoe hares in western Wyoming

Publications Posted on: January 19, 2016
Snowshoe hares (Lepus americanus) are a primary prey species for Canada lynx (Lynx canadensis) in western North America. Lynx management plans require knowledge of potential prey distribution and abundance in the western United States. Whether even-aged regenerating forests or multi-storied forests contain more snowshoe hares is currently unknown.

Winter prey selection of Canada lynx in northwestern Montana

Publications Posted on: January 19, 2016
The roles that diet and prey abundance play in habitat selection of Canada lynx (Lynx canadensis) in the contiguous United States is poorly understood. From 1998-2002, we back-tracked radiocollared lynx (6 F, 9 M) for a distance of 582 km and we located 86 kills in northwestern Montana, USA.

The effect of snowmobile trails on coyote movements within lynx home ranges

Publications Posted on: January 19, 2016
Coyotes (Canis latrans) and Canada lynx (Lynx canadensis) are sympatric throughout much of the lynx’s southern range. Researchers and managers have suggested that the presence of compacted snowmobile trails may allow coyotes to access lynx habitat from which they were previously excluded by deep, unconsolidated snow.

Activity patterns of American martens, fishers, snowshoe hares, and red squirrels in westcentral Montana

Publications Posted on: December 15, 2015
We investigated winter activity patterns of American Martens, Martes americana, Snowshoe Hares, Lepus americanus, and Red Squirrels, Tamiasciurus hudsonicus, in westcentral Montana between November 1994 and March 1995 using dual-sensor remote cameras.

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. 

Lynx and snowshoe hare response to spruce-beetle tree mortality: Evaluating habitat suitability and timber salvage in spruce-fir forests

Projects Posted on: May 20, 2015
By 2013, a spruce beetle outbreak impacted 85% of the mature spruce-fir forests on the Rio Grande National Forest. These spruce-fir forests provided some of the highest quality lynx habitat in the state. The goal of this project is to research the forest structures and compositions that lynx and snowshoe hare depend within landscapes altered by spruce bark beetle outbreak, in relation to increased post-beetle forest management activities from timber salvage.
