Researchers explain why badger culling fails to control cattle TB

Researchers have discovered the most likely reason why localised culling of badgers (Meles meles) has failed to control bovine tuberculosis (TB) in British cattle. Published online by the British Ecological Society's Journal of Applied Ecology, the study reveals that even though culling reduces badger population density, it alters their behaviour in such a way as to increase spread of the disease. The findings have major implications for future strategies to control TB in cattle.

Dr Rosie Woodroffe and colleagues from the Independent Scientific Group on Cattle TB and the Central Science Laboratory found that, where badger densities had been reduced by culling, territorial organisation was disrupted and badgers travelled more widely. Where culling was widespread, badger densities appear low enough that, despite this increased ranging, cattle herds encounter few badgers.

However, localised culling - similar to that carried out as government policy for more than 20 years - increases movement but reduces density only slightly, so that cattle herds potentially encounter more badgers than in areas without culling. These effects also help to explain new findings on the impact of badger culling on cattle TB to be published on 14 December by the journal Nature.

According to Woodroffe: "We found that badgers in and around areas subject to culling range more widely than those in undisturbed populations, potentially increasing their contact rates both with cattle and other badgers. These results help to explain why badger culling appears to have failed to control cattle TB in the past, and should be taken into account in determining what role, if any, badger culling should play in future control strategies."

Woodroffe and her team used bait marking to assess the impact of culling on badger behaviour and spatial organisation. The study was based on 13 of the 30 trial areas enrolled in the Randomised Badger Culling Trial, including Devon, Cornwall
