A STUDY OF BIODIVERSITY IN UK URBAN TREE POPULATIONS

Summary Britain's public urban spaces have been found to contain some 1360 distinct kinds of tree, of which 540 are represented by three or fewer examples. These national rarities are spread across 260 separate sites, but very few are known locally or properly appreciated by the authorities that care for them. Current trends in urban arboriculture do not promote the maintenance of such a diverse population, but many benefits can accrue from growing a wide range of trees.
