Doughnuts don’t make trees fatter

Science Spotlights Posted on: May 06, 2019
Large, old trees, often called legacy trees, serve a foundational role in old-growth forests. Restoration efforts to improve vigor of legacy trees and decrease risk to high-intensity wildland fire and drought-mediated insect mortality often include reductions in stand density. However, sometimes regulatory and social constraints limit stand-level thinning options by requiring maintenance of closed canopies.

Effects of accelerated wildfire on future fire regimes and implications for the United States federal fire policy

Publications Posted on: October 05, 2018
Wildland fire suppression practices in the western United States are being widely scrutinized by policymakers and scientists as costs escalate and large fires increasingly affect social and ecological values.

Waste to Wisdom: Utilizing forest residues for the production of bioenergy and biobased products

Publications Posted on: September 26, 2018
Forest residues, including unmerchantable and small-diameter trees, tops, and limbs, produced during thinning and timber harvest operations can be used to produce renewable bioenergy and bioproducts. The more efficient utilization of forest residues could also help offset the high costs of forest restoration activities, fire hazard treatments, post-harvest activities and forest management in general.

Influence of landscape structure, topography, and forest type on spatial variation in historical fire regimes, Central Oregon, USA

Publications Posted on: July 10, 2018
Context: In the interior Northwest, debate over restoring mixed-conifer forests after a century of fire exclusion is hampered by poor understanding of the pattern and causes of spatial variation in historical fire regimes. Objectives: To identify the roles of topography, landscape structure, and forest type in driving spatial variation in historical fire regimes in mixed-conifer forests of central Oregon.

A model-based framework to evaluate alternative wildfire suppression strategies

Publications Posted on: January 09, 2018
The complexity and demands of wildland firefighting in the western U.S. have increased over recent decades due to factors including the expansion of the wildland-urban interface, lengthening fire seasons associated with climate change, and changes in vegetation due to past fire suppression and timber harvest.

Radial and stand-level thinning treatments: 15-year growth response of legacy ponderosa and Jeffrey pine trees

Publications Posted on: December 14, 2017
Restoration efforts to improve vigor of large, old trees and decrease risk to high-intensity wildland fire and drought-mediated insect mortality often include reductions in stand density. We examined 15-year growth response of old ponderosa pine (Pinus ponderosa) and Jeffrey pine (Pinus jeffreyi) trees in northeastern California, U.S.A. to two levels of thinning treatments compared to an untreated (control) area.

Mexican spotted owls, forest restoration, fire, and climate change

Science Spotlights Posted on: October 12, 2017
The Mexican spotted owl is listed as a Threatened Species under the Endangered Species Act and is vulnerable to habitat loss from wildfire and climate change. RMRS scientists are leading a cutting-edge modeling effort to predict the interactive effects of forest restoration, wildfire, and climate change on the distribution, population size, and population connectivity of Mexican spotted owl across the Southwestern United States.  

A framework for evaluating forest restoration alternatives and their outcomes, over time, to inform monitoring: Bioregional inventory originated simulation under management

Publications Posted on: October 04, 2017
The BioSum modeling framework summarizes current and prospective future forest conditions under alternative management regimes along with their costs, revenues and product yields.

Economic opportunities and trade-offs in collaborative forest landscape restoration

Publications Posted on: September 25, 2017
We modeled forest restoration scenarios to examine socioeconomic and ecological trade-offs associated with alternative prioritization scenarios. The study examined four US national forests designated as priorities for investments to restore fire resiliency and generate economic opportunities to support local industry.

Visualization of heterogeneous forest structures following treatment in the southern Rocky Mountains

Publications Posted on: September 21, 2017
Manipulation of forest spatial patterns has become a common objective in restoration prescriptions throughout the central and southern Rocky Mountain dry-mixed conifer forest systems. Pre-Euro-American settlement forest reconstructions indicate that frequent-fire regimes developed forests with complex mosaics of individual trees, tree clumps of varying size, and openings.
