Environmental hazards are distributed in nonrandom patterns; therefore, many biologists work to predict future hazard locations from the locations of past incidents. Predictive spatial models, or risk maps, promise early warning and targeted prevention of nonnative species invasion, disease spread, or wildlife damage. The prevention of hazards safeguards both humans and native biodiversity, especially in the case of conflicts with top predators. Top predators play essential ecological roles and maintain biodiversity, but they can also threaten human life and livelihood, which leads people to eradicate predator populations. In the present article, we present a risk map for gray wolf (Canis lupus) attacks on livestock in Wisconsin between 1999 and 2006 that correctly identified risk in 88% of subsequent attack sites from 2007 to 2009. More-open habitats farther from any forest and closer to wolf pack ranges were the riskiest for livestock. Prediction promotes prevention. We recommend that the next generation of risk mappers employ several criteria for model selection, validate model predictions against data not used in model construction before publication, and integrate predictors from organismal biology alongside human and environmental predictors.

Regulated hunting may help conserve wildlife. Advocates argue hunters will champion conservation and generate revenue for management, regulation will promote sustained, stable wildlife populations, and conflicts with game species will diminish. Applying this notion to predators such as the wolf presents difficulties because of widespread human intolerance for the species. We assessed potential hunter stewardship of wolves by measuring attitudes of hunters and nonhunters in three surveys spanning 2001-2007 among 2,320 residents of four states in wolf range. Two U.S. states implemented hunting and several more are contemplating it, all as part of long-term wolf conservation. At the time of our surveys, majorities supported hypothetical wolf hunting depending on the justifications used. Likely wolf hunters showed little inclination to conserve wolves. However some predict such attitudes might change if they were allowed to hunt wolves.
