    Moreover, comparisons of coarse woody debris between old-growth and secondary longleaf pine forests are lacking despite the widely recognized value of deadwood to biodiversity in many forest types. We measured standing and fallen deadwood in three old-growth and four mature (– years-old) secondary forests in two landscapes characterized. In the model, microbial colonization of postharvest fine and woody debris drove heterotrophic respiration (R(h)), and hence decomposition, microbial growth, N mineralization and asymbiotic N(2) fixation. These processes controlled root N uptake, and thereby CO(2) fixation in regrowing vegetation.

Amounts of coarse woody debris levels found in this study ranged from 17–38 Mg/ha on the eastern side (CWHxm) to 65– Mg/ha on the western side (CWHvm) (Wells and Trofymow, ).

Coarse woody debris (CWD) is an essential component in defining the structure and function of forest ecosystems. Long-term dynamics of CWD characteristics not only affect the release rates of chemical elements from CWD, but also the species diversity of inhabiting plants, animals, insects, and microorganisms as well as the overall health of ecosystems.

Coarse Woody Debris decomposition - principles, rates and models (including insects and diseases) can add much CWD and forest harvesting activities can remove much CWD. The comprehensive study of CWD decay requires a long time period and so our knowledge is limited.

James W. McMinn and D. Crossley, Jr. Conservation of biodiversity is emerging as a major goal in the management of forest ecosystems. The contribution of coarse woody debris (CWD) to N cycling has been studied by measuring net changes in CWD N over time or in chronosequences, and through measurements of specific transfers, e.g.

N 2 fixation or leaching (e.g. Alban and Pastor,Krankina et al.,Spears et al.,Brunner and Kimmins, ).However, CWD could alter N availability and. Coarse woody debris is an important structure and function unit in forest ecosystem. This review analyzed the ecological functions of coarse woody debris in forest ecosystem and introduced several hotspots and existing problems in coarse woody debris research field.

JanuaryCoarse woody debris (CWD; large parts of dead trees) is a vital element of forest ecosystems, playing an important role in nutrient cycling, carbon storage, fire fuel, microhabitats, and overall forest structure.

However, there is a lack of effective tools for identifying and mapping both standing (snags) and downed (logs) CWD in complex natural settings. We applied a random forest machine. Coarse woody debris (CWD), represented by logs and snags >10 cm in diameter and >1 m in length, was sampled at eight sites in Russian boreal forests to determine the specific density of decay classes and decomposition rates.
