According to his team, the explosion in outdoor recreation as a result of the Covid pandemic may play a role in increased human-bear interactions. More humans visiting trails and wilderness areas naturally leads to bear encounters, which sometimes result in human injury or even death.
Human-bear conflicts, which include anything from property damage, human food raids, livestock depredation, and, yes, attacks, increase in areas where bears are expanding their range, says van Manen. In the Greater Yellowstone Ecosystem, where his studies are focused, grizzlies have tripled their range over the past 40 years, and the overlap between human use areas and grizzly territory has grown wider.
This has led to increased interactions between humans and bears, and in some cases, these interactions lead to violence. Even more recently, two more people in survived attacks by grizzlies in the park.
And, in August of , a knowledgeable hiker was killed in the backcountry. In the later, there were reports of a grizzly with a cub in the area. In the entire year history of Yellowstone National Park, there have only been a reported eight deaths including the one in , most likely caused by grizzly bears.
Bear attacks become less and less likely when you sleep at least yards away from a locking, bear-proof food container although some wily Yellowstone bears have reportedly figured these out. During this time, 44 people were injured by grizzly bears in the park. For all park visitors combined, the chances of being injured by a grizzly bear are approximately 1 in 2. The risk is significantly lower for people who don't leave developed areas or roadsides, and higher for anyone hiking in the backcountry.
Remain in developed areas, roadsides, and boardwalks: 1 in If you plan to hike, learn about the best practices for exploring bear country. Grizzly bear-inflicted injuries to humans in developed areas averaged approximately one per year during the s through the s, and four per year during the s. Grizzly bear-caused human injuries in developed areas then decreased to one injury every two years 0. Since , there have been only two 0. Over the same time span, there have been 34 human injuries caused by grizzly bears in the backcountry: an average of one per year.
Since Yellowstone was established in , eight people have been killed by bears in the park. There has never been a black bear attack resulting in a fatality within any community such as a town, city or village anywhere in Canada.
Although a bear attack is very rare, bear attacks often involve dogs off leash in a rural setting. The study determined that over half of these studied bear attacks involved a dog off leash. Dogs on a leash outdoors or in a yard are in almost all cases a deterrent, as a bear has the opportunity to avoid the dog. Bears that are familiar with human activity and do not expect harm from people rarely if ever attack.
