The impact of chronic wasting disease and its management on hunter perceptions, opinions, and behaviors in Alberta, Canada.

The goal of this analysis was to identify changes in hunting behavior, satisfaction, and perceptions of risk in the presence of chronic wasting disease (CWD). Hunters completed an Internet survey containing direct questions regarding the impacts of CWD and gathering information about real and hypothetical hunting trips. Overall, hunters were satisfied with CWD management, and although certain behaviors were altered, the perceived risk by hunters did not seem to be high. A travel cost model was used to determine whether differences in trip frequencies might be observed in response to CWD. The largest variation in trips was between urban and rural hunters, with urban hunters being less averse to traveling but more averse to CWD and the management program of extra tags.

Using expert judgments to understand spatial patterns of forest-based camping: a values-at-risk application.

Fire management agencies in Canada are mandated with protecting multiple forest values from wildfire. Deciding where to reduce fire hazard and how to allocate resources and fire suppression efforts requires an understanding of the values-at-risk from wildfire. The protection of recreation infrastructure is often assumed to provide adequate protection of recreation values. We use an expert judgment approach to provide a spatial distribution of recreation values-at-risk in the forested eastern slopes of the Rocky Mountain region of Alberta, Canada. Data were collected in 2004 from 11 land managers responsible for public lands management and wildfire prevention in the region. Expert assessments showed that recreation values were not confined to areas with publicly funded infrastructure. Exploratory spatial analysis of the ratings identified hotspots and cold spots of recreation activity. Maps resulting from these efforts will provide guidance to fire managers in the prioritization of fire management activities.

The on-ranch economics of riparian zone cattle grazing management.

A simulation model of a cattle ranch based in southern Alberta, Canada was developed to evaluate the on-ranch economics of adopting different grazing management strategies to improve riparian grazing capacity in natural grass rangeland. Under low-cost scenarios, there are positive economic incentives to adopt strategies to maintain riparian zones that already have high grazing capacity. However, riparian zones that have declined to moderate or low grazing capacity may require additional economic incentives to encourage ranches to adopt more costly management strategies to improve the grazing capacity. The economic incentives to adopt costly management strategies are highly sensitive to the size and shape of the riparian zone and rates of grazing capacity decline or improvement.
