Wildlife diseases such as bovine tuberculosis (TB) can be transmitted among wildlife directly through contact or indirectly via shared feeds; moreover diseases such as TB can also be transmitted between livestock and wildlife. Within the Riding Mountain TB Eradication Area (RMEA) in southwestern Manitoba, Canada, a federal-provincial program provides free 2.4-m-tall game wire barrier fences for stored hay bales with the objective of preventing disease transmission between cattle (Bos taurus) and wild cervids. I evaluated farmer perceptions of the effectiveness of the fences using a mail survey to all 1970 rural households (52% response rate) within the RMEA, and interviewing 50 farmers that had a game wire fence for >1 year. Half (52%) of mail survey respondents supported the idea of barrier fencing. The frequency of observing white-tailed deer (Odocoileus virginianus) on farms (cumulative AICc weight = 0.80) was the best predictor of support. Level of concern regarding TB was second most important (cumulative AICc weight = 0.56). Of the barrier fence owners interviewed, 76% agreed that fences eliminated damage to hay bales on their farms. Furthermore, 63% agreed that their fence reduced the risk of their cattle getting bovine TB.  However, only 38% agreed that their fence eliminated cattle-cervid interaction. Despite some important successes, additional work is needed to address on-going cattle-white-tailed deer-elk (Cervus canadensis) interactions on many farms. Long-term monitoring of farmer satisfaction and compliance is needed to respond to inevitable changes in the mitigation program and evaluate success relative to objectives.
