Field Results for Line Intersect Distance Sampling of Coarse Woody Debris
A growing recognition of the importance of downed woody materials in forest ecosystem processes and global carbon budgets has sharpened the need for efficient sampling strategies that target this resource. Often the aggregate volume, biomass, or carbon content of the downed wood is of primary interest, making recently developed probability proportional-to-volume designs such as line intersect d...
متن کاملAssessing the Effect of Fire Regime on Coarse Woody Debris
This study used field data and modeling to examine how coarse woody debris (CWD) differs between two areas that experienced different fire regimes (120to 300-year mean fire return intervals) in the 1500-1850 period. Although fire frequency and severity established the overall pattern of CWD succession, the interaction of fire regime with other controlling factors caused the differences in CWD m...
متن کاملSampling coarse woody debris for multiple attributes in extensive resource inventories
Information on the amount, distribution, and characteristics of coarse woody debris (CWD) in forest ecosystems is in high demand by wildlife biologists, fire specialists, and ecologists. In its important role in wildlife habitat, fuel loading, forest productivity, and carbon sequestration, CWD is an indicator of forest health. Because of this, the USDA Forest Service Pacific Northwest Research ...
متن کاملEffect of Downed Woody Debris on Small Mammal Anti-Predator Behavior
The threat of predation is often the largest cost associated with foraging (Brown & Kotler 2004; Preisser et al. 2005; Creel & Christianson 2008). Foragers primarily assess the threat of predation based on indirect cues of risk, such as microhabitat features and environmental conditions (Orrock et al. 2004; Verdolin 2006). For example, small mammals often respond to the threat of predation by b...
متن کاملThe Role of Postfire Coarse Woody Debris in Aspen Regeneration
The paucity of aspen (Populus tremuloides) regeneration in the western United States and on Yellowstone National Park’s (YNP) northern range has been of concern to managers and scientists for much of the 20th century, with the effects of ungulate browsing, climate fluctuation, and fire suppression being vigorously debated. We analyzed the interaction of fire and elk (Cervus elaphus) browsing in...
