A ‘buffer zone’ currently operates around the minimum infected area in Area 32-Cumbria; this is referred to as the outer cull area (OCA). Both the minimum infected area and the outer cull area together make up the intervention area.
The OCA is based on estimated average badger social group territory size surrounding the minimum infected area, to take into account the possibility that infection may have already spread in the badger population. The boundary was adjusted to adhere to natural barriers to badger movement as far as practical to minimise the risk of possible perturbation effects.
The results of testing of badgers from the 2019 cull are still being analysed. When completed they will inform decisions as to what type of badger control method should be applied in 2020.
