Or hedgerow; Row of closely planted shrubs or low trees, generally acting as a land division and windbreak. Hedges also serve as a source of food and as a refuge for wildlife, and provide a habitat not unlike the understory of a natural forest.
Generally, the older a hedge, the more species are found contained in a given length, roughly one species per century for a 30-yd length. About 309 species of plant occur only in hedgerows. Hedges are part of the landscape in Britain, N France, Ireland, and New England, US, but many have been destroyed to accommodate altered farming practices and larger machinery.
