That habitat includes several sintaxa of Quercetea ilicis, Cisto-Lavanduleatea, Thero-Brachypodietea, Helianthemetea guttati c ...

Old-growth forest



An old-growth forest (also termed primary forest, virgin forest, primeval forest, late seral forest, or in Britain, ancient woodland) is a forest that has attained great age without significant disturbance and thereby exhibits unique ecological features and might be classified as a climax community. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the bio-diversity of the forested ecosystem. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris.Old-growth forests are economically valuable, and logging of these forests has been a point of contention between the logging industry and environmentalists.
