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).

Fire severity and the “thermophilization” of forest understory plant communities following the Hayman Fire, Colorado

Science Spotlights Posted on: May 13, 2020
Wildfires in dry conifer forests can trigger the “thermophilization” of understory plant communities – a  decrease in the proportion of plants that prefer cool environments and moderate moisture relative to those that prefer warm, dry conditions. We used understory plant community data collected before and after the Hayman Fire to examine relationships between fire severity and thermophilization, and how those relationships varied through time.

Peromyscus carcass in the nest of a flammulated owl

Publications Posted on: February 19, 2020
The flammulated owl (Otus jlammealus) is an insectivorous species (Marshall 1957, Ross 1969) that breeds in dry, montane conifer forests of western North America. In Colorado , this owl fed primarily on small lepidopterans, although its diet included a variety of arthropods (e.g., Orthoptera, Diptera, and Arachnida) as summer progressed (Reynolds and Linkhart 1987).

Coarse woody debris in mature Pinus ponderosa stands in Colorado

Publications Posted on: December 23, 2019
During summer of 1994, 328 0.1 ha circular plots were sampled to determine the volume of coarse woody debris (CWD) and standing dead density and basal area in 53 mature or older Pinus ponderosa stands in the Front Range and Southwestern mountains of Colorado. Standing dead volume was estimated using height derived from living trees in the plots.

Fire severity and changing composition of forest understory plant communities

Publications Posted on: December 05, 2019
Gradients of fire severity in dry conifer forests can be associated with variation in understory floristic composition. Recent work in dry conifer forests in California, USA, has suggested that more severely burned stands contain more thermophilic taxa (those associated with warmer and drier conditions), and that forest disturbance may therefore accelerate floristic shifts already underway due to climate change.

Deciphering the complexity of historical fire regimes: Diversity among forests of western North America [Chapter 8]

Publications Posted on: October 02, 2019
Wildfire is a key disturbance agent in forests worldwide, but recent large and costly fires have raised urgent questions about how different current fire regimes are from those of the past. Dendroecological reconstructions of historical fire frequency, severity, spatial variability, and extent, corroborated by other lines of evidence, are essential in addressing these questions.
