Influences on Hunter Support for Deer Herd Reduction as a Chronic Wasting Disease (CWD) Management Strategy

The extent to which wildlife diseases like chronic wasting disease (CWD) are density dependent creates opportunities to manage them by implementing population reduction to disrupt disease spread and lower its prevalence. We tested a model to investigate the influence of risk perceptions and other salient beliefs on deer hunter support for deer density reduction as chronic wasting disease strategy in Wisconsin. We found that the influence of risk perceptions on hunter support for population goals was mediated through beliefs about whether eradication is necessary. Our results suggest that hunter beliefs about the likelihood of deer reduction achieving CWD eradication had the greatest influence on support for herd reduction. If managers intend to use recreational hunters to combat CWD, they need to provide tangible evidence that deer reduction results in progress in containing or eliminating CWD to increase beliefs in the efficacy of the strategy.
