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 ...
Plant Health Care (PHC) is multi-dimensional management strategy for tree and plant care to preserve the vitality of the urban and community forest. [11] Arborists and Plant Health Care Specialists apply a broad range of techniques by selecting and integrating treatment options that protect and enhance the health, structure, and appearance of ...

In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches.In freshwater ecology it refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris.
Old-growth forests tend to have large trees and standing dead trees, multilayered canopies with gaps that result from the deaths of individual trees, and coarse woody debris on the forest floor. [8] The trees of old-growth forests develop distinctive attributes not seen in younger trees, such as more complex structures and deeply fissured bark ...
This method of management was a form of cultural burning that maintained the savannah and wetland prairie system of the peninsula's low land environments.In 2008 it was found that after the suppression of these burns the area has since been forested by Douglas Firs with a decrease in the Bear Grass population.
This knowledge extends into wildlife management – how abundant, where the distribution was, and how diverse the large mammal population was. [139] While the United States has counteracted the degradation, fragmentation and loss of habitat through land set aside from all human influence, indigenous practices could inform ecosystem restoration ...
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
Salvage logging is the practice of logging trees in forest areas that have been damaged by wildfire, flood, severe wind, disease, insect infestation, or other natural disturbance in order to recover economic value that would otherwise be lost.
