Synergies between the new bioeconomy and fuel treatment for forest restoration

Events Posted on: October 06, 2020
In this webinar, RMRS research forester Nate Anderson will discuss integration of the bioeconomy and fuel treatments, including market and nonmarket values of fuel treatment and bioenergy production.  This webinar is part of our Science You Can Use series of land-management focused webinars. The sessions are half presentation, half discussion and Q&A.

Science basis for changing forest structure to modify wildfire behavior and severity

Publications Posted on: June 22, 2020
Fire, other disturbances, physical setting, weather, and climate shape the structure and function of forests throughout the Western United States. More than 80 years of fire research have shown that physical setting, fuels, and weather combine to determine wildfire intensity (the rate at which it consumes fuel) and severity (the effect fire has on vegetation, soils, buildings, watersheds, and so forth).

Forest structure and fire hazard in dry forests of the Western United States

Publications Posted on: June 22, 2020
Fire, in conjunction with landforms and climate, shapes the structure and function of forests throughout the Western United States, where millions of acres of forest lands contain accumulations of flammable fuel that are much higher than historical conditions owing to various forms of fire exclusion.

Short- and long-term effects of ponderosa pine fuel treatments intersected by the Egley Fire Complex, Oregon, USA

Publications Posted on: December 04, 2019
Fuel treatments are widely used to alter fuels in forested ecosystems to mitigate wildfire behavior and effects. However, few studies have examined long-term ecological effects of interacting fuel treatments (commercial harvests, pre-commercial thinnings, pile and burning, and prescribed fire) and wildfire.

User guide to the FireCLIME Vulnerability Assessment (VA) tool: A rapid and flexible system for assessing ecosystem vulnerability to climate-fire interactions

Publications Posted on: October 15, 2019
Decision makers need better methods for identifying critical ecosystem vulnerabilities to changing climate and fire regimes. Climate-wildfire-vegetation interactions are complex and hinder classification and projection necessary for development of management strategies.

Effectiveness of fuel treatments at the landscape scale: State of understanding and key research gaps

Projects Posted on: August 21, 2019
There is widespread interest in understanding the effectiveness of fuel treatments in mitigating the trajectory of wildfire suppression costs and how their effectiveness and longevity can be extended over large areas and landscapes. To date, there have been several studies that used a modeling approach to evaluate fuel treatment effectiveness at the landscape scale. However, empirical studies at this scale are rare because landscape-scale fuel treatment strategies have not been fully implemented or wildfires have not burned through implemented landscape fuel treatments. A thorough evaluation of what is currently available in the literature and lessons learned from forest and rangeland managers has not yet been conducted.

To masticate or not: Useful tips for treating vegetation

Science Spotlights Posted on: August 21, 2019
Recently, several large fires have burned through masticated sites – including in Colorado (Brewer et al. 2013), Washington, and New Mexico. Burning under extreme weather conditions with strong winds, these fires have challenged the benefits of using mastication, even though mastication can provide many positive environmental effects, such as soil moisture retention and cool, moist environments for soil microbes. However, informing managers when, where, and how mastication is applied is based on antidotal evidence. To address, this issue we synthesized information to provide managers with a current state of knowledge on mastication.

To masticate or not: Useful tips for treating forest, woodland, and shrubland vegetation

Publications Posted on: November 13, 2018
Forest managers use mastication to grind or shed vegetation to remove competition, prepare a site for natural or artificial regeneration, or release sapling-sized trees; or they use mastication to convert ladder fuels to surface fuels and enhance decomposition of biomass. However, determining the best mastication configuration within the context of management objectives and site limitations is challenging.

Modeling thinning effects on fire behavior with STANDFIRE

Publications Posted on: October 05, 2018
Key message: We describe a modeling system that enables detailed, 3D fire simulations in forest fuels. Using data from three sites, we analyze thinning fuel treatments on fire behavior and fire effects and compare outputs with a more commonly used model. Context: Thinning is considered useful in altering fire behavior, reducing fire severity, and restoring resilient ecosystems.

Fuels planning: science synthesis and integration; forest structure and fire hazard fact sheet 06: Guide to fuel treatments in dry forests of the Western United States: assessing forest structure and fire hazard

Publications Posted on: August 01, 2018
The Guide to Fuel Treatments analyzes a range of potential silvicultural thinnings and surface fuel treatments for 25 representative dry-forest stands in the Western United States. The guide provides quantitative guidelines and visualization for treatment based on scientific principles identified for reducing potential crown fires.
