“…Biological and social data, however, do not necessarily correlate 1 to 1. Findings reported in this article and by others ( 22,39‐41 ) suggest that psychological factors such as perceived risk play a substantial role in hunters’ decisions to hunt. Understanding concerns and perceptions of risk related to CWD can provide insight into how hunters and other stakeholder groups might react to further increases in CWD prevalence, which is essential for determining the necessity and potential effectiveness of management techniques and information campaigns.…”

This study examined factors predicted by previous research to influence hunters' decisions to stop hunting deer in a state. Data were obtained from mail surveys of resident and nonresident deer hunters in Arizona, North Dakota, South Dakota, and Wisconsin (n = 3,518). Hunters were presented with six scenarios depicting hypothetical CWD prevalence levels and human health risks from the disease (e.g., death), and asked if they would continue or stop hunting deer in the state. Bivariate analyses examined the influence of five predictor variables: (a) CWD prevalence, (b) hypothetical human death from CWD, (c) perceived human health risks from CWD, (d) state, and (e) residency. In the bivariate analyses, prevalence was the strongest predictor of quitting hunting in the state followed by hypothetical human death and perceived risk. The presence of CWD in a state and residency were weak, but statistically significant, predictors. Interactions among these predictors increased the potential for stopping hunting in the state. Multivariate analyses suggested that 64% of our respondents would quit hunting in the worst-case scenario.

“…With marksmen culling, the landowner loses their income from hunting and the recreation value because there was no compensation made to them from the state. Insights from studies on human dimensions have proved essential for understanding the limits of recreational hunters in controlling CWD in the United States (Heberlein 2004;Vaske et al 2006Vaske et al , 2018Vaske 2010;Holsman et al 2010). The perception of using marksmen in general likely depends on whether wildlife is important for livelihoods.…”

Efficacy of recreational hunters and marksmen for host culling to combat chronic wasting disease in reindeer

Most populations of large mammals in developed countries are managed by human hunting, but there are surprisingly few empirical studies about the benefits and limitations of using recreational hunters to achieve specific management objectives. In particular, the extensive host culling required to markedly reduce population densities to combat some wildlife diseases may conflict with the management aims of landowners and hunters. This is particularly acute in the case of chronic wasting disease (CWD) in cervids, which has now emerged in reindeer (Rangifer tarandus) in Norway. We analyzed the relative efficacy of approximately 1,000 recreational hunters and 30 professional marksmen during the eradication of the entire CWD-infected population of >2,000 reindeer in Norway. The government changed a series of legislation that would normally limit the efficacy of recreational hunters; these changes were linked to the duration of the hunting season, the specificity and size of the quotas, and spatial access rights. Efforts were taken to reduce both the searching time (hunters were given information on herd whereabouts) and handling time (helicopter aid for transport) of the recreational hunters. We compared 1) recreational hunting under ordinary legislation (up to 2016), 2) recreational hunting with less legislation (2017), and 3) culling by marksmen that were allowed to use both snowmobile and helicopter. Despite all of the changes in legislation, harvest by recreational hunters only increased from 241-316 during 2014-2016 to 582 reindeer in 2017 and was below management targets, while marksmen culled 1,399 reindeer, with a daily average and maximum offtake well above that of the hunters. The hunters shot more animals in the early season and during weekends. Offtake by both the hunters and marksmen were equally negatively affected by fog, which reduced visibility. We discuss the relative merits of using hunters and marksmen for wildlife control in general and limits to how legislation can increase offtake. We highlight the need for more research into how the use of marksmen comes with a cost in terms of social conflict.

“…These two types of changes in CWD condition lead to large changes in participation. Vaske (2010) also highlights the role that perceptions of human health risk play in participation decisions, but his summary of findings from a number of CWD studies indicates heterogeneity in response to CWD including some groups who substitute sites (e.g., nonresident hunters, older hunters) while other groups who stop hunting. Vaske (2010) also indicates that responses to outbreaks are relatively small, but that as prevalence increases response may increase significantly.…”

This paper examines the site choices of recreational deer hunters in context of changing levels of chronic wasting disease (CWD) and its management in Alberta. CWD is a prion disease that affects wild cervids and is found in Saskatchewan and Alberta. There are no known human health risks from CWD but the condition is fatal for cervids. The methodological approach employed utilizes both revealed and stated preference data collected from resident hunters using a computer-based survey. The results suggest that while hunting behavior is not significantly altered by current CWD levels and management programs, there would be some changes given higher prevalence and spread levels of the disease. To avoid a situation of high CWD spread and prevalence, hunters would be willing to pay on average $20.35 per trip to keep CWD at current levels. This translated into just under a million dollars of direct economic value. Although the estimate is not large compared to other provincial economic activities, when added up over a number of years the economic losses could be substantial.Le présent article examine les choix de site des amateurs de chasse au cerf en fonction de l'évolution de la maladie débilitante chronique des cervidés (MDC) et de la gestion de cette maladie en Alberta. La MDC est une maladieà prions qui frappe les cervidés sauvages, notamment en Saskatchewan et en Alberta. Cette maladie ne semble pas présenter de risques pour la santé humaine, mais elle demeure fatale pour les cervidés. Nous avons utilisé une approche méthodologique comprenant des données sur les préférences révélées et les préférences déclarées des chasseurs résidents, recueillies au moyen d'un sondage informatisé. D'après les résultats, bien que les niveaux actuels de la MDC et les programmes de gestion n'aient pas entraîné de changements considérables sur le plan du comportement de chasse, une hausse de la prévalence et des niveaux de propagation de la maladie pourrait toutefois entraîner certains changements. Afin d'éviter une augmentation de la propagation et de la prévalence de la MDC, les chasseurs se sont dit prêtsà verser en moyenne 20,35 $ par voyage de chasse pour contenir la maladie aux niveaux actuels, ce qui représenterait une valeuréconomique directe de près de un million de dollars. Bien que cette estimation soit faible par rapport aux autres activitéséconomiques provinciales, les pertes financières cumulées sur un certain nombre d'années pourraient toutefoisêtre substantielles.
