DOUBLE SAMPLING FOR COARSE WOODY DEBRIS ESTIMATIONS FOLLOWING LINE INTERSECT SAMPLING
Coarse woody debris (CWD), an essential component of healthy forests, has typically been defined as dead and down, large woody material. Quantification of this resource provides a useful metric for assessing wildlife habitat, fuel loading, and more recently, carbon sequestration. Although many CWD …

An Analysis of the Ecology and Public Perception of Coarse Woody Debris in Virginia
Coarse woody debris (CWD) is an important habitat component for wildlife, fish, and plants and is important in nutrient cycling and soil formation. Knowledge of the volume, distribution, and use of CWD across Virginia would be useful to forest managers modeling nutrient budgets in southeastern …

Coarse Woody Debris in Industrially Managed Pinus taeda Plantations of the Southeastern United States
Coarse woody debris (CWD) plays an influential role in forested ecosystems by adding organic matter to soils, stabilizing the soil environment, providing wildlife habitat, preventing soil erosion, providing seedling establishment habitat, and involvement in the nutrient cycle. Most CWD research has …

Potential of above- and below-ground coarse woody debris as a carbon sink in managed and unmanaged forests
… forest management is an increase in the stock of coarse woody debris (CWD). CWD represents a short- to middle term C sink that is of particular importance in natural and old-growth forests. Its impact on the soil organic carbon (SOC) stock is largely unknown. To investigate the impact of …

An assessment of the representation of fire severity and coarse woody debris dynamics in an ecosystem management model
… biomass and dead organic matter and post-fire coarse woody debris (CWD) dynamics. A review of the representation of fire in models was conducted and several of the most commonly used fire models in North America have been described in terms of fire severity representation. The potential for …

Effects of edge and coarse woody debris on small mammal communities in riparian and upland habitats in northern West Virginia
… response of small mammal communities to edge and coarse woody debris (CWD) volume in riparian and upland habitats of the central Appalachian Mountains has received little attention. The objectives of this study were to: (1) Perform a faunal survey of the Camp Dawson Collective Training Area in …

A study of basidiomycetes isolated from coarse woody debris and contiguous soil horizons in a mixed deciduous-conifer forest in New Hampshire, United States of America
… & E) and organic (Oe) soil layers to decomposing coarse woody debris (CWD) in a northern hardwood forest. This link supports the possibility that energy stored in woody debris can facilitate the vertical transfer of elements and compounds within the soil profile. This potential transfer implies …

The development of geomorphic and hydraulic complexity within streams and its influence on fish communities following glacial recession in Glacier Bay, Alaska
… twinned with an assessment of the role of coarse woody debris in creating such complexity at the reach and microscale levels revealed the importance of coarse woody debris in driving these changes. Coarse woody debris was found to influence the development of biocomplexity and interaction …

Methane Fluxes from Living and Dead Trees in a Temperate Forest
… as those from foliage, branches, wounds, and coarse woody debris. Recent instrumentation advances allow rapid and accurate measurements of relatively low methane flux rates in-situ; this thesis takes advantage of such technology to explore methane fluxes from these tree components in northern …

Habitat preferences of the eastern fence lizard, Sceloporus undulatus, in southwestern Virginia
… (23 °C), relatively high amounts (per 1- m2) of coarse woody debris (15%) and bare ground (15%), and relatively low amount of litter (34%). Adults and juveniles were associated with a relatively high number of rocks (22 per 0.01 hectare) and amount of coarse woody debris (9% per 1- m2). Habitat …

Amphibian Community Similarity Between Natural Ponds And Constructed Ponds Of Multiple Types In Daniel Boone National Forest, Kentucky
… including canopy cover, hydroperiod, upland coarse woody debris, aquatic vegetation, maximum depth, Ohio Wetland Rapid Assessment Score (ORAM), and pond type were recorded to examine relationships between amphibian species and habitat variables. Community comparisons were made using canonical …

Remote detection of forest structure in the White Mountains of New Hampshire: An integration of waveform lidar and hyperspectral remote sensing data
… maple abundance and low levels of sugar maple coarse woody debris. LVIS height metrics were used here to establish a statistical relationship with coarse woody debris data.</p><p>The integration of waveform lidar with hyperspectral data did enhance the ability to remotely describe a number of …

Soil Carbon Dioxide Efflux in Response to Fertilization and Mulching Treatments in a Two-Year-Old Loblolly Pine (Pinus taeda L.) Plantation in the Virginia Piedmont
… at each chamber position monthly and soil coarse fragments, soil nutrient levels, percent carbon, root biomass and coarse woody debris were measured beneath 64 chambers at the end of the study. Fertilization had no significant effect on efflux rates during any of our monthly sampling …
