Long term consequences of a controlled slash burn and slash mastication to soil moisture and CO2 at a southern Colorado site

Publications Posted on: May 23, 2013
Thinning of forest stands is frequently used to reduce the risk of catastrophic fire. But thinning requires that the refuse (or slash) be removed from the site, which can be done either by burning it or by mastication and dispersal. Either method has long term consequences to the soil and to soil moisture and soil CO2 levels.

Effects of forest management practices and environment on occurrence of Armillaria species

Publications Posted on: December 07, 2010
Influences of environment (indicated by plant associations) and forest management practices on the distribution of Armillaria spp. and genets (vegetative clones) were investigated. A total of 142 isolates of Armillaria was collected from various host trees on pristine and managed sites (thinned and/or fertilized) growing in relatively wet and dry environments in eastern Washington, U.S.A. The incidence of Armillaria spp.

Variability in nest density, occupancy, and home range size of western bluebirds after forest treatments

Publications Posted on: December 06, 2010
Complex land use and fuels management histories have resulted in significant changes in composition, structure, and function of southwestern forests and subsequent changes in the extent and quality of wildlife habitats.

Forest thinning and subsequent bark beetle-caused mortality in Northeastern California

Publications Posted on: November 08, 2010
The Warner Mountains of northeastern California on the Modoc National Forest experienced a high incidence of tree mortality (2001-2007) that was associated with drought and bark beetle (Coleoptera: Curculionidae, Scolytinae) attack. Various silvicultural thinning treatments were implemented prior to this period of tree mortality to reduce stand density and increase residual tree growth and vigor.

Fuel reduction management practices in riparian areas of the western USA

Publications Posted on: August 16, 2010
Two decades of uncharacteristically severe wildfires have caused government and private land managers to actively reduce hazardous fuels to lessen wildfire severity in western forests, including riparian areas. Because riparian fuel treatments are a fairly new management strategy, we set out to document their frequency and extent on federal lands in the western U.S.

The use of shaded fuelbreaks in landscape fire management

Publications Posted on: August 03, 2010
Shaded fuelbreaks and larger landscape fuel treatments, such as prescribed fire, are receiving renewed interest as forest protection strategies in the western United States. The effectiveness of fuelbreaks remains a subject of debate because of differing fuelbreak objectives, prescriptions for creation and maintenance, and their placement in landscapes with differing fire regimes.

A retrospective assessment of partial cutting to reduce spruce beetle-caused mortality in the southern Rocky Mountains

Publications Posted on: June 02, 2010
Tree susceptibility to bark beetle-caused mortality has been linked to stand characteristics such as basal area (BA) and average tree size, factors that can be manipulated through partial cutting. There is no experimental evidence, however, demonstrating the efficacy of partial cutting in spruce type.

Effects of fuel treatments on carbon-disturbance relationships in forests of the northern Rocky Mountains

Publications Posted on: May 06, 2010
Fuel treatments alter conditions in forested stands at the time of the treatment and subsequently. Fuel treatments reduce on-site carbon and also change the fire potential and expected outcome of future wildfires, including their carbon emissions.

Thinning and prescribed fire effects on overstory tree and snag structure in dry coniferous forests of the interior Pacific Northwest

Publications Posted on: April 07, 2010
Forest thinning and prescribed fires are practices used by managers to address concerns over ecosystem degradation and severe wildland fire potential in dry forests. There is some debate, however, about treatment effectiveness in meeting management objectives as well as their ecological consequences.

Effects of thinning and fertilizing on production of western white pine seed

Publications Posted on: March 23, 2010
In a 40-year-old western white pine plantation developed as a seed production area, heavy thinning and application of fertilizer in the fall significantly increased strobilus production the following spring. Applying fertilizer increased seed weight and cone length significantly, but thinning did not. Insects severely damaged the cone crop in the thinned stand.
