A reanalysis of nutrient dynamics in coniferous coarse woody debris
Canadian Journal of Forest Research, 2001We 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 ...

Coarse woody debris in Australian forest ecosystems: A review
Austral Ecology, 2005Abstract 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.

Point relascope sampling of downed coarse woody debris
Canadian Journal of Forest Research, 1999This 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, 2012Abstract 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

Coarse Woody Debris: Humans and Nature Competing for Trees
Journal of Forestry, 1999Abstract 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.

The imprint of coarse woody debris on soil chemistry in the western Oregon Cascades
Biogeochemistry, 2004Coarse woody debris (CWD) may create a spatially discrete soil imprint through the release of carbon rich, acidic dissolved organic matter (DOM). DOM has been implicated in many soil processes such as humus formation, nutrient immobilization, podzolization, and the dissolution of soil minerals.

Coarse woody debris as a refuge from predation in aquatic communities
Oecologia, 1993This study demonstrates experimentally that coarse woody debris (CWD) can provide refuge from predation in aquatic habitats. In the Rhode River subestuary of Chesapeake Bay, Maryland, (USA), we (1) measured the abundance of CWD, (2) examined the utilization of CWD by mobile epibenthic fish and crustaceans, and (3) tested experimentally the value of CWD

Coarse woody debris mass and nutrients in forest ecosystems of Korea
Ecological Research, 2006Abstract Coarse woody debris (CWD) is an essential component of forests. However, quantification of both the mass and nutrient content of CWD within a given environment tends to be a fairly labor‐intensive proposition that requires long‐term studies to be conducted for viable data to be obtained.

[Coarse woody debris and its function in forest ecosystem].
Ying yong sheng tai xue bao = The journal of applied ecology, 2001Coarse woody debris (CWD) is an important structural and functional element in forest ecosystem. In this paper, the definition, dynamics, and role of CWD in a forest ecosystem were overviewed. CWD include all woody debris above and under the ground with a diameters > or = 2.5 cm, and mainly comes from the dead trees resulted from competition and ...

Coarse woody debris in a Carpathian subalpine spruce forest
Forstwissenschaftliches Centralblatt, 2001Number, volume and size of snags, broken and uprooted trees as well as advancement of their decomposition and arrangement were analysed in a subalpine spruce forest in the Babia Gora massif (West Carpathians). The most important results are: 1. The amount of coarse woody debris noted on Babia Gora was among the highest in subalpine spruce forests,
