What drives ponderosa pine regeneration following wildfire in the western United States?

Publications Posted on: December 05, 2019
Ponderosa pine (Pinus ponderosa Lawson & C. Lawson) is a prominent tree species in forests of the western United States. Wildfire activity in ponderosa pine dominated or co-dominated forests has increased dramatically in recent decades, with these recent wildfires often burning in an uncharacteristic manner due to past land management activities and changing climate.

Engelmann spruce seed production is influenced by climate

Science Spotlights Posted on: August 26, 2019
In 1968, thirteen permanent research plots were established in Engelmann spruce-subalpine fir forests along an elevational gradient on the Fraser Experimental Forest. Seed traps were installed on these plots and have been sampled annually since 1968. In 2011, tree cores were sampled to examine the relationship between climate and seed production.

Wildland shrubs - their biology and utilization

Publications Posted on: July 31, 2019
Why Is a Shrub Symposium Needed? The answer to this question is obvious in view of the great volume of research that has been done with grasses and forbs while, in contrast, there has been considerably less research and development of shrubs. Yet, shrubs offer tremendous potentials for man's benefit in making the arid and semi - arid lands of the world more productive and useful.

Growth response of whitebark pine (Pinus albicaulis Engelm) regeneration to thinning and prescribed burn treatments

Publications Posted on: October 03, 2018
Whitebark pine (Pinus albicaulis Engelm.) forests play a prominent role throughout high-elevation ecosystems in the northern Rocky Mountains, however, they are vanishing from the high mountain landscape due to three factors: exotic white pine blister rust (Cronartium ribicola Fischer) invasions, mountain pine beetle (Dendroctonus ponderosae Hopkins) outbreaks, and successional replacement by more shade-tolerant tree species historically contro

Landscape-scale assessments of whitebark pine

Science Spotlights Posted on: August 23, 2018
Forest inventory data show that more than half of all standing whitebark pine trees in the U.S. are dead. Regeneration of whitebark pine is widespread, especially in lodgepole pine stands, which suggests that active management of whitebark pine should target mixed-species stands to take advantage of natural regeneration. 

Coram Experimental Forest: 50 years of research in a western larch forest

Publications Posted on: August 01, 2018
This publication will enrich public understanding about the important contributions to science made at this and other outdoor laboratories. Coram, and other long-range research sites, provide scientific knowledge to assist resource professionals with the development of sound land management principles. This knowledge ensures healthy, sustainable, and productive ecosystems while meeting social and economic needs.

Whitebark pine distribution and regeneration

Media Gallery Posted on: June 04, 2018
Whitebark pine (Pinus albicaulis) is an ecologically important species in high-altitude areas of the West due to the habitat and food source it provides for Clark’s nutcrackers, red squirrels, grizzly bears, and other animals. Whitebark pine stands have recently experienced high mortality due to wildfire, white pine blister rust, and a mountain pine beetle outbreak, leading to questions about the species’ long-term viability. This project seeks to quantify the current distribution and regeneration status of whitebark pine throughout its US range.
