- The Trough fire occurred in August 2001 on the Mendocino National Forest of northern California. A burned area emergency rehabilitation team evaluated the fire effects on the watershed. Concerns were soil from the denuded slopes moving into streams affecting fishery values, reservoir sedimentation and storm runoff plugging culverts leading to road wash outs. Past evaluations have shown hand straw mulching to be a superior method in protecting soil from raindrop impact, surface runoff and erosion. However, hand mulching is a long and expensive process with safety factors dictating mulching...AuthorsRobert FaustSourceIn: Narog, Marcia G., tech. coord. 2008.

- Restoring the natural fire regime to forested systems that have experienced fire exclusion throughout the past century can be a challenge due to the heavy fuel loading conditions. Fire is being re-introduced to mixed conifer forests in the Sierra Nevada through both early season and late season prescribed burns, even though most fires historically occurred in the late season. We assessed the impact of early and late season prescribed fires on soil biogeochemical and microbiological parameters that are important for ecosystem recovery. We found that the late season burns had more dramatic...AuthorsSarah T. Hamman, Ingrid C. Burke, Eric E. KnappSourceForest ecology and management 256(3): 367-374Year2008
- Concerns about the use of genetically appropriate material in restoration often focus on questions of local adaptation. Many reciprocal transplant studies have demonstrated local adaptation in native plant species, but very few have examined how interspecific competition affects the expression of adaptive variation. Our study examined regional scales of adaptation between foothill and coastal populations of two California native bunchgrasses (Elymus glaucus and Nassella pulchra). By combining competitive manipulations with reciprocal transplants, we examined the importance of the vegetation...AuthorsRice Kevin J., Eric E.

- Large diameter, old trees are an important component of functioning forests, as they provide habitat for many wildlife species and add value to the scenery along roads and trails that cross our National Forests and Parks. Tree mortality, from prescribed or wild fire, is of great concern to forests managers, especially mortality of those of large diameter. Raking away the litter and duff around the base of these desired trees has been advocated as a way to reduce tree mortality during prescribed burns. We tested the effectiveness of raking to reduce tree mortality in two burn areas in...AuthorsWilliam F. Laudenslayer, George N. Steger, Jonathan ArnoldSourceIn: Narog, Marcia G., tech. coord. 2008.

- There is growing interest in using biomass removed from hazardous fuels reduction treatments in wood-fired electrical generation facilities. An application of FIA BioSum to southwest Oregon’s Klamath ecoregion assessed the financial feasibility of fuel treatment and biomass generation under a range of product prices and fire hazard-motivated silvicultural prescriptions. This simulation framework consisted of linked models developed on a foundation of Forest Inventory and Analysis data. Small diameter woody biomass and merchantable volume and pre and post-treatment fire hazard were character...AuthorsJeremy S. Fried, Jamie Barbour, Roger D.

- A methodology for incident decomposition and reconstruction is developed based on the concept of an "event-frame model." The event-frame model characterizes a fire incident in terms of (a) environmental events that pertain to the fire and the fire context (e.g., fire behavior, weather, fuels) and (b) management events that represent responses to the fire environment. The model defines a sequential set of eventframes according to temporal and contextual factors (e.g., management processes) that yield a visual representation of an incident decomposition. The set of eventframes decomposes an...AuthorsDonald MacGregor, Armando Gonzalez-CabanSourceRes. Pap.

- Mulching after wildfires is a common treatment designed to protect bare ground from raindrop impact and reduce subsequent erosion. We tested the effectiveness of three mulching methods on the Indian Fire near Prescott, Arizona, USA. The first method felled all fire-killed trees, chipped the logs and limbs, and spread the chips across the hillslope with a mobile selffeeding chipper. The second treatment spread compressed, tackified straw pellets that expand when wetted and release a soil flocculant. The third treatment was rice straw applied at 4.5 Mg ha-1 (2 tons ac-1). Each treatment was...AuthorsGeorge H. Riechers, Jan L. Beyers, Pete R. Robichaud, Karen Jennings, Erin Kreutz, Jeff MollKeywordsSourceIn: Narog, Marcia G., tech. coord.

- Determining the gender of American martens (Martes americana) and fishers (M. pennanti) from track plate stations would significantly augment the information currently gathered from this simple and inexpensive survey method. We used track-plate impressions collected from captured individual martens and fishers of known gender to develop methods to distinguish the gender from tracks. We collected marten tracks from two subspecies M. a. sierrae (tracks n = 54, individuals m = 12, f = 8) and M. a. humboldtensis (tracks n = 109, individuals m = 10, f = 9). We developed a model for martens...AuthorsKeith M. Slauson, Richard L. Truex, Bill ZielinskiSourceNorthwest Science 82(3): p. 185-198Year2008
- Sustainable forest management integrates ecological, social, and economic objectives. To achieve the former, researchers and practitioners are modifying silvicultural practices based on concepts from successional and landscape ecology to provide a broader array of ecosystem functions than is associated with conventional approaches. One such innovation is disturbance-based management. Under this approach, forest practices that emulate natural ecological processes, such as local disturbance regimes, are viewed as more likely to perpetuate the evolutionary environment and ecosystem functions...AuthorsMalcolm P.
