A pollarded alder tree, Alnus glutinosa, in Borrowdale, Cumbria, UK. Pollarding is a wood management technique in which all growth is removed from the tree above 2-3m at intervals of several years. This provides a supply of small wood, and has the incidental benefit of prolonging the lifespan of the tree. Alder wood was traditionally used for making clogs in the North of picture, taken in May, shows a tree at a field boundary one year after it was last pollarded. Regrowth is visible from the edges of previously cut branches, and also as epicormic shoots growing directly from the bole of the tree. These shoots are susceptible to grazing, but the topmost regrowth is out of reach
