Despite intensive efforts over the last century to eradicate bovine tuberculosis (TB) in North America, several hotspots of infected wildlife and livestock remain, raising concerns that the disease will never be eradicated. The stress and frustration for a farmer caused by having a herd test positive for TB or living in an infected region can be substantial. The goal of this study was to investigate the concerns of farmers around Riding Mountain National Park (RMNP) regarding the presence of TB in wildlife and livestock and conduct an exploratory analysis of causal factors. Data were collected from 786 farmers within 50 km of RMNP using a mail-back questionnaire. Overall, farmers indicated a high level of concern toward diseases in both wildlife and cattle relative to other concerns. The spatial variables that had the greatest influence on TB concern were both the distance of farms to the RMNP boundary and distance of farms to previous cases of TB. The most important aspatial factor associated with high TB concern was the frequency with which farmers observed elk on their land. These results underscore the important differences between 'objective' measures of risk, such as epidemiological estimates of disease prevalence, and subjective measures of disease concern, such as risk perception and acceptability of management actions. Written responses suggest that concerns regarding disease may affect how farmers view wildlife on their land and their relationship with neighbouring protected areas. Management activities that reduce the frequency of elk interactions with farms, but also recognize the complex relationship that farmers have with wildlife and protected areas, will be most effective in mitigating farmer concern regarding this important problem.
尽管在上个世纪为根除北美牛结核病付出了巨大努力,但仍存在几个野生动物和家畜感染的热点地区,这引发了人们对该病永远无法根除的担忧。牛群结核病检测呈阳性或生活在感染地区给农民带来的压力和挫折可能很大。本研究的目的是调查骑马山国家公园(RMNP)周边农民对野生动物和家畜中结核病存在的担忧,并对因果因素进行探索性分析。使用回邮问卷从RMNP周边50公里范围内的786名农民那里收集了数据。总体而言,相对于其他担忧,农民对野生动物和牛的疾病表示高度关注。对结核病担忧影响最大的空间变量是农场到RMNP边界的距离以及农场到以前结核病病例的距离。与高结核病担忧相关的最重要的非空间因素是农民在其土地上观察到麋鹿的频率。这些结果强调了“客观”风险衡量指标(如疾病流行率的流行病学估计)与疾病担忧的主观衡量指标(如风险认知和管理行动的可接受性)之间的重要差异。书面回复表明,对疾病的担忧可能会影响农民对其土地上野生动物的看法以及他们与邻近保护区的关系。减少麋鹿与农场互动频率,但同时认识到农民与野生动物和保护区之间复杂关系的管理活动,将最有效地减轻农民对这一重要问题的担忧。
