High forest
A high forest is a type of forest originated from seed or from planted seedlings. In contrast to a low forest, a high forest usually consists of large, tall mature trees with a closed canopy. High forests can occur naturally or they can be created and/or maintained by human management. Trees in a high forest can be of one, a few or many species. A high forest can be even-aged or uneven-aged. Even-aged forests contain trees of one, or two successional age classes. Uneven-aged forests have three or more age classes represented.
High forests have relatively high genetic diversity compared with coppice forests, which develop from vegetative reproduction. A high forest can have one or more canopy layers. The understory of a high forest can be open, or it can be dense. A high forest's understory can have high or low vegetation species diversity.
