Most scientific experts agree that data from the initial trial badger culling areas in Gloucestershire, Somerset and Dorset do not justify further extension of culling (Scientists criticise badger cull extension, 31 August). In ignoring this advice, and extending culling to five new areas, the government risks not only wasting much money but also giving farmers false hope that the approach will contribute to reducing TB in cattle. The initial trial areas were set up to test whether free-range shooting could be done humanely and at the same time reduce badger populations by at least 70% – the figure previously established as the level needed to achieve a significant reduction in TB in cattle.
The government was able to announce last year that it had achieved its culling targets, but only because they were based on unrealistically low badger population estimates – not on the central or best estimate value, but on the lowest bound value of the statistical margin of error around this estimate. This was simply a fudge. In none of these exercises did it achieve a 70% reduction based on the most likely population estimate.
