Coarse woody debris (CWD) or coarse woody habitat (CWH) refers to fallen dead trees and the remains of large branches on the ground in forests [1] and in rivers or wetlands. [2] A dead standing tree – known as a snag – provides many of the same functions as coarse woody debris. The minimum size required for woody debris to be defined as ...

That July day, Sam Lewis, the Forest Service feller boss for the project, walked up to a large tree with bug holes and dead branches. With an ax, he struck the ponderosa pine a few times, and cut ...
The lower-intensity fires used up accumulated dried, dead trees, branches and leaves on the forest floor, and better spaced and diversified the forest and its mix with wetlands and grasslands.
Xiphydriidae bore and feed into dying or weakened trees so they do not have a negative effect to the environment. [10] They can be a secondary pest to humans because of the dead wood people may bring into their homes. [8] Xiphydriidae can be a host for parasitoid Aulacidae and they emerge from larvae that are fully grown. [11]
Deciduous trees tend to shed dead branches and heal over the wound, while conifers often retain the dead limb, which naturally becomes weathered and eroded over time. Most deadwood techniques for the tree's trunk apply equally well to deciduous and to conifer bonsai, although the driftwood style (in which much of the trunk is dead) is generally ...
