The Value of Dead Trees

Every tree dies eventually and its ecological value continues long after the last leaf falls. Whether it still stands, is reduced to a hollowed stump, or exists as downed wood, most of its “life” occurs in a complex, intriguing, unseen world. Imagine a time-share that is used by different species, for vastly different purposes, in every stage of its demise. Most species that use snags are associated with those that are about 15” in diameter though many benefit from smaller trees. No man-made structure matches the ecological usefulness of a sizeable dead tree; and few living things are as overlooked and unappreciated, except of course by wildlife and the vast industry of inhabitants at work on its remains beneath the soil.

Nature bequests dying trees to enrich habitats. A dead tree is a legacy that can take dozens of years to replace, and in many cases, it will never be. Whenever a tree is cut down needlessly and hauled away prematurely we short-change our urban forests and our planet. Dead trees represent one of the finest examples of reciprocity with the environment. A study of its relationship with wildlife and organisms above and beneath the soil is a profound illustration of the fact that individuality and independence in our ecosystems is an illusion.
