Prism sweeps for coarse woody debris

Canadian Journal of Forest Research, 2003
A new method for sampling coarse woody debris (CWD) is presented, based on relascope sampling of CWD midpoint diameter. In this method, CWD is included in a sample if the angle subtended by the midpoint diameter viewed from plot center is greater than the critical relascope angle. The method is therefore referred to as diameter relascope sampling (DRS).

Coarse woody type: A new method for analyzing coarse woody debris and forest change

Forest Ecology and Management, 2006
The species composition of both standing live and down dead trees has been used separately to determine forest stand dynamics in large-scale forest ecosystem assessments. The species composition of standing live trees has been used to indicate forest stand diversity while the species composition of down dead trees has been used to indicate wildlife ...

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.

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

Coarse woody debris in forest regions of Russia

Canadian Journal of Forest Research, 2002
To assess regional stores of coarse woody debris (CWD) in seven major forest regions of Russia, we combined data collected as part of the routine forest inventory with measurements in 1044 sample plots and the results of density sampling of 922 dead trees. The stores of CWD in the western part of Russia (St.

Ecological functions of coarse woody debris in forest ecosystem

Journal of Forestry Research, 2005
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.

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.

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

Ecology of Coarse Woody Debris in Temperate Ecosystems

1986
Publisher Summary This chapter reviews the rates at which Coarse Woody Debris (CWD) is added and removed from ecosystems, the biomass found in streams and forests, and many functions that CWD serves. CWD is an important component of temperate stream and forest ecosystems and is added to the ecosystem by numerous mechanisms, including wind, fire ...
