Knowra Deadwood Deadwood Deadwood is dead or decaying woody material in forests, including standing dead trees, fallen trunks, branches, and stumps. It provides habitat, stores carbon, and contributes to nutrient cycling.
Forest biodiversity : The variety of species, genes, and ecological communities found in forests. Deadwood creates habitat niches that increase the range of forest organisms.
Wood decomposition : The breakdown of woody tissues by organisms and physical processes. This process turns deadwood into smaller compounds, soil organic matter, and gases.
Snag : A standing dead or dying tree, usually lacking most or all of its crown. Snags are the standing form of deadwood and provide cavities, perches, and feeding sites.
Old-growth forest : A forest with long ecological continuity and structures produced by natural growth and disturbance. Many old-growth forests contain abundant large logs and standing dead trees.
Carbon cycle : The movement of carbon among organisms, the atmosphere, oceans, and Earth’s land systems. As wood decomposes, deadwood releases stored carbon and transfers it through the forest.
Saprotrophic fungi : Fungi that obtain nutrients by decomposing dead organic matter. They produce enzymes that break down the resistant compounds in dead wood.
Coarse woody debris : Large fallen or cut pieces of wood, such as logs, branches, and stumps. This term identifies the substantial downed material commonly measured in forests.
Białowieża Forest : A forest complex on the Poland–Belarus border containing some of Europe’s best-preserved lowland old-growth forest. Its largely unmanaged stands illustrate high deadwood volumes and diverse decay stages.
Nutrient cycling : The movement and reuse of chemical elements through ecosystems and organisms. Decomposition returns nutrients held in wood to forest soils and living organisms.
White rot : Wood decay that breaks down lignin along with cellulose and hemicellulose, often leaving pale material. It is one pathway by which fungi dismantle the lignin-rich structure of deadwood.
