Long-term effects of tree expansion and reduction on soil climate in a semiarid ecosystem

Publications Posted on: September 29, 2020
In sagebrush ecosystems, pinyon and juniper tree expansion reduces water available to perennial shrubs and herbs. We measured soil water matric potential and temperatures at 13-30 and 50-65 cm soil depths in untreated and treated plots across a range of environmental conditions. We sought to determine the effects of tree expansion, tree reduction treatments, and expansion phase at time of treatment over 12-13 yr post-treatment.

Colorado Front Range fuel photo series

Publications Posted on: June 22, 2020
This photo series was developed to help fire managers estimate ground and surface fuel loads that exist in cover types of the Southern Colorado Front Range wildland-urban interface. Photos and associated data representing low, medium, and high fuel loadings from this study are presented by forest type, along with examples of typical or median fuel loadings that were encountered.

Fire ecology and management in lowland riparian ecosystems of the southwestern United States and northern Mexico

Publications Posted on: December 06, 2019
Lowland riparian ecosystems, defined as those occurring at elevations at or below 5,000 feet (1,564 meters), constitute a small fraction of total land area in the southwestern United States and northern Mexico, yet they are extremely important to human livelihoods and biotic communities.

Rangeland Production Monitoring Service: In season forage and fuel projections

Tools Posted on: July 08, 2019
Rangeland vegetation growth is highly variable, often exceeding 40 percent variation on an interannual basis.

New research quantifies future wildfire impacts to communities in the Western United States

FS News Posted on: June 18, 2019
The Forest Service has developed a new cross-boundary assessment tool that maps 240 million acres where significant wildfire ignitions can potentially impact over 1,800 Western communities. This new framework is described in the report Cross-boundary Wildfire and Community Exposure Assessment (RMRS-General Technical Report-392), which was recently released by the USDA Forest Service Rocky Mountain Research Station and Oregon State University.

Next Generation Fire Severity Mapping

Tools Posted on: July 06, 2018
The Next Generation Fire Severity Mapping is a tool designed to depict the probability of high-severity fire, if a fire were to occur, for several ecoregions in the contiguous western U.S. Statistical models were used to generate “wall-to-wall” maps for 13 of the 19 ecoregions. 

The Cooney Ridge Fire Experiment: An early operation to relate pre-, active, and post-fire field and remotely sensed measurements

Publications Posted on: May 11, 2018
The Cooney Ridge Fire Experiment conducted by fire scientists in 2003 was a burnout operation supported by a fire suppression crew on the active Cooney Ridge wildfire incident. The fire experiment included measurements of pre-fire fuels, active fire behavior, and immediate post-fire effects.

Slash from the past: Rehabilitating pile burn scars

Pages Posted on: April 05, 2018
In the National Forests of northern Colorado, there is a backlog of over 140,000 slash piles slated to be burned, most of them coming from post-mountain pine beetle salvage logging and hazard reduction treatments. Burning slash piles can create openings in the forest that remain treeless for over 50 years, and can also have the short-term impacts of increasing nutrient availability and creating opportunities for weed establishment. Working with managers, RMRS researchers have evaluated the available treatments for short-term rehabilitation of both smaller, hand-built and larger, machine-built burn piles. For the smaller piles, they found that both soil nitrogen and plant cover recovered to a level similar to that of the surrounding forest within two years, indicating that these scars may not need rehabilitation unless in a sensitive area. Seeding with native mountain brome (Bromus marginatus) was an effective option for the larger piles, whereas mechanical treatment either alone or with seeding did not increase plant cover.

Fuel PARticle DYnamics (FPARDY)

Projects Posted on: April 04, 2018
FPARDY (Fuel PARticle DYnamics), is one of many new efforts to explore surface fuel characteristics at the particle, layer, and fuelbed levels across major forest ecosystem types in the US northern Rocky Mountains (NRM) to develop a set of products that integrate these findings into standard fuel applications.
