100 years of vegetation change at the Sierra Ancha Experimental Forest

Projects Posted on: March 08, 2019
This project incorporates historical data collected at the Sierra Ancha Experimental Forest nearly 100 years ago to determine how plant communities have changed over that period of time.

Erosion and site productivity in western-montane forest ecosystems

Documents and Media Posted on: October 17, 2018
Soil loss from erosion affects site productivity by reducing the nutrient pool and water-holding capacity of the soil and by direct damage to vegetation. The effects of erosion depend on the type of erosion processes because of differences in the depth and areal extent of soil loss, the downslope rate of soil movement, and the probability of redeposition of eroded material.Document Type: Other Documents

Promoting revegetation and soil carbon sequestration on decommissioned forest roads in Colorado, USA: A comparative assessment of organic soil amendments

Publications Posted on: October 04, 2018
Forest roads are commonly decommissioned and revegetated to decrease erosion, prevent weed encroachment, manage recreation and improve overall watershed condition on federal lands, but may also provide a complementary opportunity to sequester carbon (C) in soils.

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.

Road scholars for the western states: Protecting natural areas by improving road management research

Pages Posted on: March 29, 2018
A poorly placed or unsuitably designed road can result in landslides, flooding, gullies, stream damage, and wildlife habitat destruction. Particularly in natural areas, benefits of roads, such as accessibility and convenience, must be weighed against potential water quality degradation, scenic and wildlife habitat destruction, and hazardous driving conditions. Scientists at the Rocky Mountain Research Station helped create two free tools—GRAIP (Geomorphic Road Analysis and Inventory Package) and GRAIP-Lite—to help land managers make better decisions about road management in environmentally sensitive areas. GRAIP helps land managers analyze and predict surface erosion, gully risk, landslide risk, stream crossing failure risks, and other hazards. GRAIP-Lite allows land managers to quickly compare roads and road lengths in terms of their potential impact on the environment.

A rapid response database in support of post-fire hydrological modeling

Publications Posted on: January 06, 2017
Being prepared for an emergency is important. Every year wildfires threaten homes and lives, but danger persists even after the flames are extinguished. Post-fire flooding and erosion (Figure 1) can threaten lives, property, and natural resources.

Targeting forest management through fire and erosion modeling

Publications Posted on: January 06, 2017
Forests deliver a number of important ecosystem services, including clean water. When forests are disturbed by wildfire, the timing, quantity and quality of runoff are altered. A modelling study was conducted in a forested watershed in California, USA, to determine the risk of wildfire, and the potential post-fire sediment delivery from ~4-ha hillslope polygons within a 1500-km2 basin following a wildfire event.

Fire research of the Southwest Watershed Science Team

This web site displays some of the past and current fire-related activities of the Southwest Watershed Science Team of the RMRS Air, Water, Aquatic Ecosystems Program.

Post-fire bedload sediment delivery across spatial scales in the interior western United States

Publications Posted on: November 07, 2016
Post-fire sediment yields can be up to three orders of magnitude greater than sediment yields in unburned forests. Much of the research on post-fire erosion rates has been at small scales (100m2 or less), and post-fire sediment delivery rates across spatial scales have not been quantified in detail.

Effectiveness of three post-fire rehabilitation treatments in the Colorado Front Range

Publications Posted on: November 07, 2016
Post-fire rehabilitation treatments are commonly implemented after high-severity wildfires, but few data are available about the efficacy of these treatments. This study assessed post-fire erosion rates and the effectiveness of seeding, straw mulching, and contour felling in reducing erosion after a June 2000 wildfire northwest of Loveland, Colorado.
