Badger setts are protected under the Protection of Badgers Act 1992. Understanding legal requirements protects both badgers and developers from criminal prosecution.
Interference with active badger setts during the breeding season (February-May) causes direct pup mortality as cubs are unable to thermoregulate without adult body contact. Development work near setts without appropriate surveys and licensing risks both welfare harm and criminal prosecution. Artificial sett creation allows genuine mitigation when development impacts are unavoidable, but must be completed and colonised before the original sett is affected. Wildlife crime relating to badger sett destruction frequently goes undetected and unprosecuted. Reporting suspected interference to the Wildlife Crime Unit is an important welfare protection mechanism.
