Young Brunette Girl Reveals On The Rocky Beach With Remains Of A Dead Tree

In Glen Affric, Scotland, the Trees for Life group found the black tinder fungus beetle (Bolitothorus reticulatus) is dependent on a particular fungus (Fomes fomentarius), which itself grows only on dead birch. Another insect, the pine hoverfly (Blera fallax), requires rotting Scots Pine in order to reproduce.
In certain subtropical areas such as Australia where bushfire constitutes a major hazard, the amount of CWD left standing or lying is determined by what may be considered safe in the course of reasonable fire prevention. However, when fires do occur, invertebrates find shelter either within or beneath dead tree logs.
In Canada, bears seek out dead tree logs to tear open and look for and feed on ants and beetles, a fact that has encouraged the authorities to reserve a sufficient amount of coarse woody debris for these purposes. In North America, too, CWD is often used as barriers to prevent browsing deer and elk from damaging young trees.
