Artificial Badger Sett Creation & Main Sett Closure
Client: Richards Ecology
Keystone were commissioned to create a large artificial Badger sett comprising fifteen chambers with eight entrance holes and multiple linking tunnels in addition to two annexe setts as mitigation for a residential development in Helston, Cornwall.
Once constructed, the artificial sett was closely monitored for signs of occupation. Once occupancy was successfully achieved, the existing main sett within the development site could be subsequently closed by installing vertical Badger proof fencing around the entire perimeter of the sett complete with two-way exclusion gates.
Following the exclusion phase the main sett was successfully vacated and subsequently closed following a destructive search of the site.
