Black bears in Yosemite

Black bears (Ursus americanus) are the only species of bear found in Yosemite National Park. Despite their name, most of Yosemite's black bears are not actually black, but are brown or even blond or reddish-brown. Adult male black bears weigh around 250 pounds, while adult females weigh around 150 pounds.

Black bears are omnivores and their diet mainly consists of grasses, berries, and acorns in the fall. They are also excellent climbers and can easily climb trees to avoid danger or to reach food. During the fall, black bears in the Sierra Nevada are preparing for winter and will soon enter hyperphagia, where their appetite increases dramatically. This can push bears to look for food where people are, so it's important to secure buildings and prevent bears from breaking in.

In winter, black bears hibernate and enter a state of reduced body temperature, pulse rate, and respiration that conserves energy. Female black bears give birth while in hibernation to a litter of one to three cubs, which stay with their mothers until they are about 16 to 17 months old.

Bear incidents in Yosemite

Bear incidents occur when bears cause monetary loss, property damage, or obtain food from people. It can also include cases where bears cause injury to people. The Bear Team at Yosemite National Park manages and monitors bear incidents in the park. In 2022, there were 25 bear incidents reported in Yosemite, down 50% compared to last year and down 98% compared to 1998, the year with the most incidents. Of these incidents, 8 occurred in the wilderness, 1 in campgrounds, 5 in residential areas, and 11 in other areas.

Despite their size and strength, attacks by black bears are rare in Yosemite, and no one has been killed or seriously injured by a black bear. Visitors should keep a distance of at least 50 yards from bears in undeveloped areas and scare them away in developed areas. Bears may show dominance by bluff charging, especially when guarding food or cubs. Visitors should drive the speed limit and follow food storage regulations to preserve the species that can be negatively affected by humans.

Bear-resistant food storage

To help prevent bear encounters, the park has implemented a strict policy requiring visitors to properly store their food and trash in bear-resistant containers. Federal regulations require proper food storage in Yosemite National Park. Food includes all food, drinks, trash, toiletries, and other scented items. Food must be stored in a bear-resistant food container or food locker. Hanging food is illegal throughout Yosemite. Certain bear-resistant portable containers designed for backpackers are allowed, and the Garcia Backpackers' Cache 812 is available for rental in Yosemite.

Food lockers are available at designated campsites in Little Yosemite Valley and adjacent to the five High Sierra Camps, but personal locks are not allowed. Bear-resistant containers increase your freedom in selecting campsites away from developed or highly used areas. Make sure all scented items are inside the container. The container must be closed and locked, even while you're around your campsite. Place the container 25 to 50 feet from your campsite, in a place where a bear can't easily roll it away.

It's also important to note that bears have an excellent sense of smell and can detect even the slightest scent of food from a distance. So, it's crucial to keep all food, beverages, and toiletries inside the bear-resistant container, including trash and cooking utensils that have come in contact with food.

Additionally, you should never leave food unattended while cooking or eating, and all food waste should be burned or packed out. It's also a good idea to clean up any spills or crumbs that may attract bears.

In the event that you encounter a bear while camping, it's important to stay calm and avoid direct eye contact. Slowly back away and make noise to alert the bear to your presence. Never run or climb a tree, as bears are excellent climbers and runners.

Remember that bears are wild animals and should always be treated with respect and caution. By following these guidelines, you can help prevent human-bear conflicts and ensure a safe and enjoyable camping experience for everyone involved.
