Abstract

Wolf-caused depredation results in substantial economic loss to individual farmers and can lead to greater public animosity towards wolves (i.e., reduction in social tolerance) and the agencies that manage depredations. Using an experimental design in field trials, we are testing shock collars, fladry, and livestock guarding dogs to determine if they are effective in reducing wolf use of areas in Wisconsin and Michigan. During 2003-2004, we equipped 5 wolves with shock collars and found that a 14-day shock period resulted in a decline in wolf use of baited sites by 50% compared to control wolves that increased visitation to baited sites by 18%. During 2005, we found that all pack members in shock-collared wolf packs (n = 5) avoided shock sites for over 60 days after being exposed to a 40-day shock period. During 2004-2005, we found that fladry offered farms at least 90 days of protection from wolves. During 2006-2008, we are conducting field trials with livestock guarding dogs on Michigan farms using an experimental design protocol and additional field trials of shock collars in Wisconsin. Our preliminary data suggest that shock collars and fladry may reduce wolf use of areas within their pack territories. Results of this research will provide important guidelines for implementing potential non-lethal management measures in areas wolves have recolonized or will likely recolonize in the near future and/or where wolves are being reintroduced.

Abstract

Abstract Although wolves (Canis lupus) and many other carnivores are habitat generalists, certain landscape features can be used to predict suitable habitat. Thiel examined the concept of road density as [...]

Abstract

Bioboundaries, also called biofences, are deterrents that attempt to exploit certain innate behaviors to exclude wildlife from target areas. We hypothesized that human-deployed scent marks and playbacks of foreign howls could simulate a territorial gray wolf (Canis lupus) pack impinging on a resident pack, thereby causing the resident pack to move. During summer 2010, we deployed a simulated-pack bioboundary near 3 wolf packs in northern Wisconsin and monitored their movements relative to 3 wolf packs experiencing a sham treatment, to control for effects of human presence. We analyzed wolves’ locations (≥1 location per week) and used linear models with mixed effects to examine distance from the rendezvous site as a function of treatment (sham or experimental) and phase of treatment (before or after treatment was initiated), while accounting for variations in individual wolves. We found little evidence that biofences, as configured and deployed in this study, caused wolves to change use of their territory.
