Wolf culls, in order to prevent livestock predation, have been shown to increase the amount of livestock killed

However, these reductions are not guaranteed, as removing badgers from an established population changes the behaviour of the survivors. The disturbance caused by shooting or gassing badgers results in artificially changed dynamics inside the sett, forcing the animals to move. Dispersal puts diseased badgers into contact with more healthy ones, and more cattle too. Simply put, unless you kill every single badger, the survivors move around, resulting in an increase in bovine TB. This increase will undoubtedly be more significant with a badly organised, shambolic cull such as we have seen over the past year.
