A California fire prevention guide recommends to "Remove all tree branches at least 6 feet [1.8 meters] from the ground" and "Allow extra vertical space between shrubs and trees." [3] In British English, limbing can be synonymous with snedding. Alternatively, limbing can be used to describe the operation on larger branches, and snedding on smaller.
Other traits such as serotiny and fire-stimulating flowering also have evolved for millions of years. [6] Some species are capable of using flammability to establish their habitats. For example, trees evolved with fire-embracing traits can "sacrifice" themselves during fires. But they also cause fires to spread and kill their less flammable ...
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.

Forces may include wind, fire, heat, lightning, rain, attack from insects (such as ants or beetles), bacteria, or fungi. Also, trees may self-prune, dropping lower branches as they reach maturity, exposing the area where the branch was attached. Many animals further develop the hollows using instruments such as their beak, teeth or claws. [1] [3]
These ecosystems had the highest fire frequency of any habitat, once per decade or less. Without fire, deciduous forest trees invade, and their shade eliminates both the pines and the understory. Some of the typical plants associated with fire include yellow pitcher plant and rose pogonia. The abundance and diversity of such plants is closely ...
Several trees normally have marcescent leaves such as oak (Quercus), [5] beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows . [6] All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. [ 7 ]
