Projects Posted on: April 24, 2019
Climate Change Vulnerability Assessment in Support of Front Range National Forests and Colorado National Grasslands for Forest Plan Revision, Plan Amendments, and Project-Level Planning.

First-year postfire and postharvest soil temperatures in aspen and conifer stands

Publications Posted on: August 01, 2018
Aspen (Populus tremuloides Michx.) stands are in decline throughout the Interior Western United States because of fire suppression, overbrowsing by domestic livestock and native ungulates, and forest succession.

Our forests in the [water] balance

Pages Posted on: May 15, 2018
  Climate change is not only causing temperatures to rise, it is also altering the amount and type of precipitation that falls across the western United States. Research shows a trend of increasingly dry “dry years,” meaning droughts are becoming more severe and streams are flowing lower during these periods. Forests play an important role in delivering high quality water to streams, but climate change is affecting this role. Drought can cause tree mortality due to lack of water or reduced resistance to insects and disease. Dry fuels and stressed vegetation in forests also increases the potential for large wildfires. When many trees die in a forest fire or from disease or insect outbreaks, the amount of water entering nearby streams often increases. However, so does the delivery of sediment to these streams through erosion. These changes call on resource managers and communities in the West to start conversations today about addressing water supplies in the future. In addition, silviculturists, fuel specialists, and aquatic ecologists can work together to maintain a holistic view of ecosystems that, above all, considers where forests fit in the water balance.

Doing more with the core: Proceedings of the 2017 Forest Inventory and Analysis (FIA) Science Stakeholder Meeting; 2017 October 24- 26; Park City, UT

Publications Posted on: October 17, 2017
The Forest Service’s Forest Inventory and Analysis Program (FIA) is the primary source of information about our forests’ status and trends. A network of nationally consistent field observations forms FIA’s core, and active collaboration with clients and peer organizations ensures that the resulting inventory remains agile, comprehensive, and relevant.

Observed and anticipated impacts of drought on forest insects and diseases in the United States

Publications Posted on: July 15, 2016
Future anthropogenic-induced changes to the earth’s climate will likely include increases in temperature and changes in precipitation that will increase the frequency and severity of droughts. Insects and fungal diseases are important disturbances in forests, yet understanding of the role of drought in outbreaks of these agents is limited. Current knowledge concerning the effects of drought on herbivorous insect and pathogen outbreaks in U.S.

An assessment of forest ecosystem health in the Southwest

Publications Posted on: May 12, 2016
This report documents an ecological assessment of forest ecosystem health in the Southwest. The assessment focuses at the regional level and mostly pertains to lands administered by the National Forest System. Information is presented for use by forest and district resource managers as well as collaborative partners in the stewardship of Southwestern forests.

Using Forest Health Monitoring to assess aspen forest cover change in the southern Rockies ecoregion

Publications Posted on: May 12, 2016
Long-term qualitative observations suggest a marked decline in quaking aspen (Populus tremuloides Michx.) primarily due to advancing succession and fire suppression. This study presents an ecoregional coarse-grid analysis of the current aspen situation using Forest Health Monitoring (FHM) data from Idaho, Wyoming, and Colorado.

Second Forest Vegetation Simulator Conference; February 12-14, 2002; Fort Collins, CO.

Publications Posted on: May 12, 2016
The Forest Vegetation Simulator (FVS) is a computer program that projects the development of forest stands in the United States and British Columbia, Canada. The proceedings of the second FVS conference, held in Fort Collins, CO, includes 34 papers dealing with applications of FVS that range from the stand-level through full-scale landscape analyses.

Root diseases: primary agents and secondary consequences of disturbance

Publications Posted on: May 12, 2016
The fact that endemic root disease causing pathogens have evolved with forest ecosystems does not necessarily mean they are inconsequential. A pathogen such as the P group of Heterobasidion annosum has become an intractable problem in many Sierra east side pine stands in California because the fungus is adapted to colonization of freshly cut stump surfaces.

Assessment and response to bark beetle outbreaks in the Rocky Mountain area

Publications Posted on: May 12, 2016
Bark beetles act as "agents of change" within the conifer forests of the Rocky Mountain area. They play a critical role in the development, senescence, and rebirth of Western forests. Bark beetle-caused tree mortality can be extensive, covering thousands of acres.
