Bear-Caused Human Fatalities In Yellowstone National Park: Characteristics And Trends, Kerry A. Gunther
Bear-Caused Human Fatalities In Yellowstone National Park: Characteristics And Trends, Kerry A. Gunther
Human–Wildlife Interactions
Three fatal bear (Ursus spp.) attacks in Yellowstone National Park (YNP), USA, from 2011 to 2015 were a catalyst for YNP managers to evaluate the circumstances of bear-caused fatalities as well as the bear safety messages it distributes to park visitors. I reviewed records of all fatal bear attacks that occurred in YNP from 1872 to 2018. Seven of the 8 fatalities were caused by grizzly bears (U. arctos horribilis). The per capita risk of being killed by a grizzly bear was 1 fatality for every 26.2 million park visits. Most fatal bear attacks in YNP involved …

Human–Wildlife Interactions
Range expansion of American black bears (Ursus americanus; bear) and residential development have increased the bear presence in suburbia. Suburban landscapes exhibiting patchworks of variable-sized parcels and habitats and owned by landowners with diverse values can create large areas of suitable habitats with limited public access. These landscapes may limit the effectiveness of hunting as a traditional bear population management tool. Managers require better information regarding landowner attitudes about hunting before implementing harvest regulations intended to mitigate conflicts in suburban areas. To address this need, in 2013, we surveyed landowners to identify properties that allowed bear hunting in 3 …

Black Bears Recolonizing Historic Ranges: Indiana Human–Bear Interactions, Bradford J. Westrich, Emily B. Mccallen, Geriann Albers
Human–Wildlife Interactions
Over a century after extirpation from Indiana, USA, 2 American black bears (Ursus americanus) were confirmed in the state during the summers of 2015 and 2016. The first bear encountered a public and management agency unaccustomed to living with large carnivores, which resulted in intentional and unintentional feedings, habituation, and ultimately its euthanasia. The Indiana Department of Natural Resources (DNR) attempted to learn from this encounter and began preparing for the next transient black bear. Education materials were created to help minimize human–bear interactions, promote living safely with bears, and inform about what to do when encountering a …

Human–Wildlife Interactions
DNA-based capture-mark-recapture (CMR) techniques are commonly used to obtain population parameters of black bears (Ursus americanus) in rural and wildland landscapes; however, these techniques have not been implemented in urban clusters (i.e., 2,500 to 50,000 residents). Black bears can readily habituate to urban clusters, and wildlife managers need to monitor and manage these urban bear populations. We modified DNAbased CMR for black bear using hair-snares to take into account the small home ranges of urban bears, urban bear behavior, and human safety within Mammoth Lakes, California, USA. We conducted this study for 3 fi eld seasons in 2010, 2011, and …

Human–Wildlife Interactions
Conflict between black bears (Ursus americanus) and humans has occurred in Utah, but the records are largely incomplete. To document these events, the Utah Division of Wildlife Resources initiated a black bear sightings and encounters database in 2003, and we updated it. From 2003–2013, there were 224 recorded events, with 10 attacks, 208 property damages, and 6 vehicle collisions. Most events took place at campsites (40%). The most common season for events was summer (78%). Most conflict occurred at night. The number of events has not increased over the last 10 years, with no significant relationship between the …
