Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith
Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith
Human–Wildlife Interactions
Developing the capacity to predict black bear (Ursus americanus; bear) activity in a diversity of habitats will help conserve bear populations and their habitats and minimize human–bear conflicts. This capacity will be particularly important in areas that provide bear habitat and offer backcountry hiking and camping experiences. Bryce Canyon National Park (BRCA), located on the edge of the Paunsaugunt Plateau in southern Utah, USA, provides important bear habitat and offers visitors 12 backcountry campsites. To effectively manage these areas to minimize human–bear conflicts, park managers will need better information about black bear use of these campsites and other …
Portable Electric Fencing For Bear Deterrence And Conservation, Tom S. Smith, Bryan Hopkins, John Gookin, Samantha Thompson
Portable Electric Fencing For Bear Deterrence And Conservation, Tom S. Smith, Bryan Hopkins, John Gookin, Samantha Thompson
Human–Wildlife Interactions
Although bear-inflicted (Ursus spp.) human fatalities are rare in North America, human injuries, property damage, and bear mortalities occur wherever bears and humans commingle. We investigated the efficacy of portable electric fencing systems for bear deterrence under a variety of environmental conditions in the lab and field. Our results showed that the bear deterrent systems we evaluated were effective in protecting humans, their food, and property from bears >99% of the time. Herein, we discuss the benefits of using electric fencing, reasons why fences sometimes fail, and provide guidance regarding the most effective implementation of the systems we evaluated. …
Black Bear Exclusion Fences To Protect Mobile Apiaries, Tammy E. Otto, Gary J. Roloff
Black Bear Exclusion Fences To Protect Mobile Apiaries, Tammy E. Otto, Gary J. Roloff
Human–Wildlife Interactions
Demand for commercial bee (Apis mellifera) services recently has increased, resulting in greater use of mobile apiaries for crop pollination. When commercial apiaries are moved into areas occupied by black bears (Ursus americanus), conflicts between beekeepers and bears sometimes occur. Commercial pollination often involves moving apiaries among agricultural fields, and, thus, permanent fencing is not a viable option for reducing damage by bears. In 2010, we tested the effectiveness of 4 temporary electric fence designs for excluding black bears from bait sites in northern Michigan. We determined the effectiveness of each fence design by observing bear …
Carnivores, Urban Landscapes, And Longitudinal Studies: A Case History Of Black Bears, Jon P. Beckmann, Carl W. Lackey
Carnivores, Urban Landscapes, And Longitudinal Studies: A Case History Of Black Bears, Jon P. Beckmann, Carl W. Lackey
Human–Wildlife Interactions
As urban landscapes expand across the globe, it becomes imperative to understand how these landscapes affect large carnivore populations. We examined the effects of humanaltered landscapes on age-specific fecundity and life history parameters for female black bears (Ursus americanus) in urban and wildland regions in the northern Sierra Nevada Mountains of Nevada, including the Lake Tahoe Basin. We followed 12 marked female bears in an urban environment and 10 females in wildland habitats from 1997–2006. Our results show that female bears in urban areas have higher age-specific fecundity rates than did wildland female bears. Despite this difference, female …
