Grazing After the Burn
Year: 2012
The rangelands and dry forests of Eastern Washington are considered “disturbance-driven” ecosystems. Disturbances are simply events that disturb normal ecosystem processes: nutrient and water cycling, plant growth and reproduction, animal interactions, etc. While all ecosystems experience some forms of disturbance, areas (like Eastern Washington) with extreme temperature variation, rough topography, scarcity of water, high soils variability, and high fire frequency experience more frequent and more severe disturbance than a Florida swamp forest, for an obvious example. Fire and grazing are…

Developing Socioeconomic Performance Measures for the Watershed Condition Framework
Year: 2012
The purpose of this report is to propose principles and strategies for creating socioeconomic performance measures, as well as identify potential measures that could be integrated into the WCF and other restoration frameworks in the short term. It also recommends a longer-term strategy to develop a social condition assessment and performance accountability system that could be paired with the WCF and terrestrial condition framework currently being developed. Finally, this report identifies potential barriers and challenges to adopting new performance measures, and potential approaches to…

Wildfire Suppression Contracting: The Effect of Local Business Capacity During Large Wildfires
Year: 2012
Contracting capacity and local capture can be the result of local economic conditions (supply side conditions) as well as agency contracting practices (demand side conditions). In order to capture contracts locally, local businesses that can perform the work need to exist, and past experience contracting with the federal government is a reasonable indicator of that capacity. To better understand local contracting capacity, we examined how local contract capture varied between wildfires and the relationship between local capture and contracting capacity measures. We investigated how the number…

Disposing of Woody Material
Year: 2008
Thinning to reduce hazardous fuels often generates large amounts of woody residues, such as small-diameter logs, tree tops, and branches. This publication discusses several options for economically and effectively using and disposing of woody material.

Mechanical Treatments
Year: 2008
Many manual and mechanical methods are used to reduce hazardous fuels on woodland properties. This publication describes three of the most common methods: Slashbusting and grinding Mowing and mastication Crushing Mechanical methods use several types of equipment to chop, chip, crush, or otherwise break apart fuels—such as brush, small trees, and slash—into small pieces or chips. The processed fuels carpet the ground, forming a relatively dense, compact layer of woody material. The material may be integral to the prime mover or may be then is left to decompose or is burned.Mechanical…

Pruning
Year: 2008
Pruning is removing the lower branches of trees. Increasing the distance between the ground and the lowest tree branches reduces the likelihood that a fire on the ground will use the branches as a ladder to move into tree crowns. A crown fire is more difficult to control and can advance much more rapidly than a surface fire, under certain weather conditions.Pruning is a particularly effective fuels-reduction technique when combined with other forms of treatment such as thinning.

Thinning
Year: 2008
Thinning is one of the most powerful forest management tools available to landowners for achieving a wide range of goals and objectives. Thinning influences: Trees’ growth rates and potential economic value Which species of trees and other plants will be in the stand Trees’ resistance to insects and disease Quality of wildlife habitat Forage production The stand’s aesthetic appearance Another, very important effect is that thinning increases a forest’s ability to survive wildfire.Thinning is: Removing trees that, if left in the stand, could increase fire risk and could lessen stand vigor (for…
