The costs of carrying out the culling are being borne by the farmers. Cage trapping and shooting would cost £2,500 per square kilometre per year, and shooting free-running badgers would cost £300 per square kilometre per year.
The Environment Department estimates culling will cost farmers an average of £1,000 per square kilometre per year, which for the west Gloucestershire cull would come to £1.2 million over the four-year period and in west Somerset would be £1 million.
The monitoring, licensing and policing costs will be met by the taxpayer and come to £3.2 million for each pilot area. The policing costs alone are expected to be in the region of £2 million for each pilot cull.
