Snag (ecology)

Common card · No. 478444

In forest ecology, a snag is a standing dead or dying tree, often missing a top or most of the smaller branches. In freshwater ecology the term snag 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. Snags provide habitat for a wide variety of wildlife but pose hazards to river navigation. When used in manufacturing, especially in Scandinavia, they are often called dead wood and in Finland, kelo wood.
