Badgers live in complex social clans with strong territorial bonds - disruption from development, persecution, and culling affects social welfare at the clan level.
Badger social welfare is a dimension of their conservation that is often overlooked. Clan social bonds are complex and take years to develop - badger clans with stable membership have better welfare indicators than disrupted groups. Development that destroys setts, illegal badger baiting (still widespread), and culling all disrupt social structures. The welfare cost of disrupted social groups includes increased aggression, loss of cooperative foraging knowledge, and stress from territorial instability. Protecting setts and reducing social group disruption is both a welfare and conservation priority.
