Zoologists from Trinity College Dublin, working with a multi-disciplinary team of veterinarians and ecologists from the Department of Agriculture, Food and The Marine (DAFM) and the National Parks and Wildlife Service (NPWS), have discovered a brand new ‘super-ranging’ behaviour in badgers, which has major implications for implementing vaccination programmes to limit the spread of bovine tuberculosis (TB). The findings come at an opportune time, after DAFM recently announced it would be rolling out a national programme to vaccinate badgers in its efforts to eradicate TB.
