Low stocks of coarse woody debris in a southwest Amazonian forest

Oecologia, 2007
The stocks and dynamics of coarse woody debris (CWD) are significant components of the carbon cycle within tropical forests. However, to date, there have been no reports of CWD stocks and fluxes from the approximately 1.3 million km(2) of lowland western Amazonian forests.

Estimating uncertainty in the volume and carbon storage of downed coarse woody debris [PDF]

Ecological Applications, 2019
AbstractDowned coarse woody debris, also known as coarse woody detritus or downed dead wood, is challenging to estimate for many reasons, including irregular shapes, multiple stages of decay, and the difficulty of identifying species. In addition, some properties are commonly not measured, such as wood density and carbon concentration.

The combustion of sound and rotten coarse woody debris: a review

International Journal of Wildland Fire, 2011
Coarse woody debris serves many functions in forest ecosystem processes and has important implications for fire management as it affects air quality, soil heating and carbon budgets when it combusts. There is relatively little research evaluating the physical properties relating to the combustion of this coarse woody debris with even less specifically ...

Concept and Classification of Coarse Woody Debris in Forest Ecosystems

Frontiers of Biology in China, 2006
Coarse woody debris (CWD) is generally considered as dead woody materials in various stages of decomposition, including sound and rotting logs, snags, and large branches. CWD is an important functional and structural component of forested ecosystems and plays an important role in nutrient cycling, long-term carbon storage, tree regeneration, and ...

Point relascope sampling of downed coarse woody debris

Canadian Journal of Forest Research, 1999
This paper presents a method based on angle-gauge sampling useful for inventorying downed coarse woody materialin forest stands. The method is closely related to transect relascope sampling, except that sample points are used rather than line transects. Theestimators for the total and per unit area are given along with theestimators of their variances.

The influence of coarse woody debris on gravel beach geomorphology

Geomorphology, 2012
Abstract Coarse woody debris (CWD) is an important component of fluvial systems affecting in-channel hydrology and sediment storage which in turn controls channel geometry and evolution. The role of coarse woody debris in coastal geomorphology is an emerging research field and this study investigates its role on mixed sand and gravel beach systems. A

A reanalysis of nutrient dynamics in coniferous coarse woody debris

Canadian Journal of Forest Research, 2001
We analyzed net N, P, K, Ca, and Mg fluxes from decaying coarse woody debris (CWD) by developing a "volume-adjusted method" and applying it to existing chronosequence studies of CWD in temperate coniferous forests. Unadjusted nutrient concentrations may overestimate the amount of a given nutrient remaining or accumulating in CWD, because mass loss ...

Transport and retention of coarse woody debris in mountain streams: An in situ field experiment of log transport and a field survey of coarse woody debris distribution [PDF]

Water Resources Research, 2002
Although coarse woody debris (CWD) is an important component of stream ecosystems in forested areas, the processes of CWD distribution, transport, and retention have not been clarified. In this study the distribution process of CWD pieces shorter than the bankfull width (S‐CWD) is discussed using an in situ field experiment of log transport and a field

Coarse woody debris in Australian forest ecosystems: A review

Austral Ecology, 2005
Abstract Coarse woody debris (CWD) is the standing and fallen dead wood in a forest and serves an important role in ecosystem functioning. There have been several studies that include estimates of CWD in Australian forests but little synthesis of these results.

Coarse Woody Debris: Humans and Nature Competing for Trees

Journal of Forestry, 1999
Abstract Dead wood is usually the last thing foresters and forest products companies want to see in their forests. However, before humans discovered so many practical uses of wood, dead and dying trees were basic to forest development. Not surprisingly, many plants and animals evolved dependencies on dead wood.
