High forest
A high forest is a type of forest originated from seed or from planted seedlings. In contrast to a low forest[1] (also known as a coppice forest), a high forest usually consists of large, tall mature trees with a closed canopy.[2] High forests can occur naturally or they can be created and 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.[3] [4] Even-aged forests contain trees of one, or two successional age classes (generations). Uneven-aged forests have three or more age classes represented.[citation needed ]
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 (parklike, easy to see and walk through), or it can be dense. A high forest's understory can have high or low vegetation species diversity.[citation needed ]
