Sett

A badger sett or set is a badger's den, usually consisting of a network of tunnels. The largest setts are spacious enough to accommodate 15 or more animals, with up to 300 metres (980 ft) of tunnels and as many as 40 openings. It takes many years for the animals to dig these large setts. Setts are typically excavated in soil that is well drained and easy to dig, such as sand, and situated on sloping ground where there is some cover.
