Lick Creek: Lessons learned after 20+ years of fuel treatments in a ponderosa pine forest

Science Spotlights Posted on: September 08, 2020
Lick Creek is the longest running fuel treatment and restoration study of ponderosa pine forests in the northern U.S. Rocky Mountains. Through repeat photography and numerous published studies, we show how fuels and vegetation have changed over the 25 years since treatment and compare the effects of mechanical harvesting with and without prescribed burning.

Drying rates of masticated fuelbeds

Science Spotlights Posted on: August 20, 2020
Wildfires that burn masticated fuels often cause severe ecological damage. Managers need to know how fast the fuelbeds dry so they can implement actions to mitigate potential adverse effects. 

Drying rates of saturated masticated fuelbeds from Rocky Mountain mixed-conifer stands

Publications Posted on: August 10, 2020
Mastication is becoming a popular wildland fuel treatment in the United States but little is known about how masticated fuels dry over time, especially as these atypical fuelbeds age. This report summarises measured drying rates of different-aged masticated fuelbeds built from material collected from sites that were treated using one of four mastication techniques.

Comprehensive comparative economic evaluation of woody biomass energy from silvicultural fuel treatments

Publications Posted on: April 16, 2020
Fuel treatments are used in overstocked, fire-prone forests to alter wildfire behavior and reduce fire risk. Some of the benefits they provide are not captured in markets, and therefore represent unaccounted environmental externalities that can lead to inefficient decision making.

Prescribed fire regimes subtly alter ponderosa pine forest plant community structure

Publications Posted on: March 05, 2019
Prescribed fire is an active management tool used to address wildfire hazard and ecological concerns associated with fire exclusion and suppression over the past century.

Mechanized fuel treatment effects on soil compaction in Sierra Nevada mixed-conifer stands

Documents and Media Posted on: October 03, 2018
The immediate need to treat forest fuels is often justified as a need to reduce potential fire behavior as well as improve or maintain forest health. Millions of hectares are at risk of unusually severe fires in the United States, and fuel treatments are being prescribed at unprecedented scales. In many cases, mechanical treatments with heavy equipment are the most efficient or economical method to reduce fuels.Document Type: Other Documents

Mulch matters: Mulching fuels treatments promoted understory plant communities in Colorado forests

Pages Posted on: July 11, 2018
Rocky Mountain Research Station (RMRS) Research Ecologist Paula Fornwalt and her team initiated a long-term study in 2007 to better understand how mulching fuels treatments impacted understory plant communities in three Colorado forest types: pinyon pine - juniper (PJ), ponderosa pine and ponderosa pine - Douglas-fir (PP), and lodgepole pine and mixed conifer (LPMC). 

Fire regimes approaching historic norms reduce wildfire-facilitated conversion from forest to non-forest

Publications Posted on: April 23, 2018
Extensive high-severity wildfires have driven major losses of ponderosa pine and mixed-conifer forests in the southwestern United States, in some settings catalyzing enduring conversions to nonforested vegetation types. Management interventions to reduce the probability of stand-replacing wildfire have included mechanical fuel treatments, prescribed fire, and wildfire managed for resource benefit.

Fire and fuel treatments increase tree resistance to bark beetles

Science Spotlights Posted on: April 10, 2018
The frequency of fire in low-elevation coniferous forests in western North America has greatly declined since the late 1800s. In many areas, this has increased tree density, increased the proportion of shade-tolerant species, reduced resource availability, and increased forest susceptibility to forest insect pests and high-severity wildfire. This study investigated how low-intensity fire affects tree defenses and whether fuel treatments impact resistance to a mountain pine beetle outbreak.
