Analysis of sampling methods for coarse woody debris

Forest Ecology and Management, 2004
Abstract Coarse woody debris (CWD) is an important structural component of forest ecosystems and plays a key role in ecosystem functioning. It includes whole fallen trees and branches, pieces of fragmented wood, stumps, and standing dead trees (snags). A number of sampling approaches have been used to quantify CWD but there has been little systematic

Effects of elevated UV-B radiation and N deposition on the decomposition of coarse woody debris.

Science of the Total Environment, 2019
Increases in nitrogen (N) deposition and ultraviolet-B (UV-B) radiation play an important role in global climate change. Because coarse woody debris (CWD) represents a sizeable proportion of total carbon (C) pool in forest ecosystems, understanding the ...

Assessment of Coarse Woody Debris

1998
In this paper, different probability sampling methods for assessing coarse woody debris (CWD) are compared. The methods are circular plot sampling, strip surveying, line intersect sampling, and transect relascope sampling. The two latter methods are suited primarily for the assessment of CWD on the ground.

Dendroecological Applications to Coarse Woody Debris Dynamics

2017
Coarse woody debris plays a crucial role in forest ecosystems. The current amount of woody debris on a given site represents a balance between additions (tree mortality) and depletions (wood decomposition, combustion, transport). Understanding woody debris dynamics has recently gained much attention, primarily because of the need to improve forest ...

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.

Effects of forest dieback on wood decay, saproxylic communities, and spruce seedling regeneration on coarse woody debris

Fungal ecology, 2019
Picea is one of the most dominant conifer genera in the Northern Hemisphere and includes species which require coarse woody debris (CWD) as a seedbed for regeneration.

Coarse Woody Debris Quantity and Distribution in Central European Streams

International Review of Hydrobiology, 2000
Summarized here are ten investigations concerning the volume of coarse woody debris (CWD) in Central European streams. Altogether, 69 stream sections were examined ranging from Northern German lowland streams to brooks in alpine regions. Most of the study streams are according to Central European standards quasi-natural and are bordered by deciduous ...

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 Dynamics in Two Old-Growth Ecosystems

BioScience, 1991
In this article, the dynamics of coarse woody debris are compound deciduous old-growth forest system Changbai Mountain Biosphere Reserve in China, and a coniferous old-growth forest system, H. J. Andrews Experimental Forest in Oregon. The objective is to compare in these two ecosystems the amount of coarse woody debris; the processes that affect coarse

Coarse woody debris is affected by the frequency and intensity of historical harvesting and fire in an open eucalypt forest

Australian Forestry, 2019
We examined the effects of timber harvesting and fire history on coarse woody debris (CWD) at 48 sites dispersed across the dry sclerophyll jarrah (Eucalyptus marginata) forest of south-western Western Australia. These sites represent a range of fire and
