The bacterium which causes bovine TB, spreads from cattle to badgers and badgers to cattle. The Department is striving to interrupt this spread by expanding its badger vaccination programme across the country. As with all vaccination programmes, population penetration is key to its success. Therefore, knowledge of all badger setts is critical to the programme. The Department has a dataset of the location of some 47,000 badger setts but there are many more unknown setts scattered across the country. This new app will allow farmers to assist the Department in locating these setts and therefore extend the vaccination programme. Badgers are a protected species under the Irish Wildlife Act and the capture of badgers under the wildlife programme is subject to licence from the National Parks and Wildlife Service. The vaccination programme will protect badgers and cattle from the devastating effects of bovine TB. There is no vaccination approved for use in cattle.
