The deciduous Sweet chestnut was introduced into the UK by the Romans for its nuts - often ground into flour - and widely planted for its timber; but it now behaves like a native tree, particularly in South East England where it spreads through many woodlands by seed. It can grow old and massive, the trunk twisting and developing fissures, and the branches collapsing, but often taking root and sending up new shoots. One of the largest sweet chestnut trees is in Gloucestershire, its trunk measuring nearly 13m across.What to look for
The sweet chestnut has long leaves with large teeth along their edges, and soft-spined fruit cases that contain two or three chestnuts.Where to find
