Woodland is used in British woodland management to mean tree-covered areas which arose naturally and which are then managed, while forest is usually used in the British Isles to describe plantations, usually more extensive, or hunting Forests, which are a land use with a legal definition and may not be wooded at all. The term ancient woodland is used in British nature conservation to refer to any wooded land that has existed since 1600, and often (though not always) for thousands of years, since the last Ice Age (equivalent to the American term old-growth forest).
Woodlot is a closely related American term which refers to a stand of trees generally used for firewood. While woodlots often technically have closed canopies, they are so small that light penetration from the edge makes them ecologically closer to woodland than forest.
In Australia, a woodland is defined as an area with sparse (10–30%) cover of trees, and an open woodland has very sparse (<10%) cover. Woodlands are also subdivided into tall woodlands, or low woodlands, if their trees are over 30 m (98 ft) or under 10 m (33 ft) high respectively. This contrasts with forests, which have greater than 30% cover by trees.
