Badgers are protected by the The Protection of Badgers Act 1992 which consolidates and improved previous legislation (including the Badgers (Further Protection) Act 1991). It is a serious offence to kill, injure or take a badger, or to damage or interfere with a sett unless a licence is obtained from a statutory authority.
Surveys are undertaken to establish the presence of badgers and the location of their setts and foraging habitats. This involves searching for signs such as footprints, hairs and latrines. If signs are found then a detailed sett status assessment and monitoring can be used to determine potential impacts and to plan the appropriate mitigation.
