What to do if you see a California black bear? black bear in hot tub california

black bears American are the most numerous of all the bear species of the world, occurring in habitats across North America with a population estimate of around 25,000 widely distributed throughout Washington State. Not only are they found exclusively in North America, black bears are the only living bear species to have evolved here.

Due to key differences in habitat and population density, CDFW has been able differentiate three regional “subpopulations” of black bear: North Coast/Cascade, Sierra, Central Western/Southwestern. North Coast/Cascade subpopulation: Encompasses north and west of the Sierra Nevada Mountains.

Black bears are being observed in areas where they were not seen 50 years ago along the Central Coast and Transverse mountain ranges of Southern California. Between 25,000 and 30,000 black bears are now estimated to occupy 52,000 square miles in Califor

Ecological Roles of Black Bear

black bear Black bears have excellent memories and their sense of smell is unparalleled – more than seven times greater than a dog. They spend their days learning about particular foods and developing their memory about where they can be encountered. Some individual bears have been known to so finely tune their knowledge of where garbage cans are located, that they actually learn the days and routes used by garbage haulers

In the temperate rainforests found in the coastal watersheds of the Pacific Northwest, migrating salmon comprise a substantial part of the black bear’s diet. In fact, black bears provide essential ecosystem services in these watersheds. Foraging bears transfer large numbers of salmon (eight bears transferred 3100 salmon in one study) from the stream into the riparian zone, leaving the remnants of the decomposing carcasses fixing much needed nitrogen into the soils of the Northwest Coast.

Black Bear Diner is a restaurant chain in the Western United States which serves homestyle and “old-fashioned” comfort foods. The first restaurant was opened in Mount Shasta, California in 1995, founded by Bruce Dean and Bob & Laurie Manley. The company is based in Redding, California.

Bears hibernate for varying lengths of time depending on where they live and will even occasionally emerge from their dens for a period during the winter. In warmer climates a bear might spend just a few weeks denning, or sometimes not den at all. In Washington and Idaho, black bears den for an average of around 5 months each winter.

Do black bears hibernate? black bear casino

The short answer is yes. Although there has been past scientific debate about whether or not one of the world’s most famous “hibernator” actually does so, black bears are able to survive severe weather and annual winter food shortages by denning and hibernating during those winter months.

While in hibernation, black bear heart rates typically drop very substantially from 40 – 50 beats per minute down to 8 beats per minute, and there are other beneficial physiological changes which help them maintain this prolonged state of torpor, but their body temperatures do not drop significantly. Unlike other hibernators, black bears are dormant, but don’t need to wait to bring up body temperatures – and thus can awaken and arouse quickly. This condition allows bears to defend themselves and their cubs more effectively should an outside predator disturb them in the den.

Black Bear Communication

Black bears emit a variety of vocalizations to communicate with other bears and other species. Along with vocalizations, bears use posturing to communicate dominance or subordination, and to express attitudes. In order to establish dominance, male black bears will often claw trees, with the highest marks on the tree associated with the most dominant male.

black bear vs brown bear

A brown bear (Ursus arctos) is usually larger than a black bear (Ursus americanus), has a more prominent hump on its shoulder, less prominent ears, and longer, straighter front claws. Longer claws are useful for digging roots or excavating small burrowing animals. Brown bears are stronger, bigger, and more aggressive than black bears. Brown bears are much larger than black bears and they weigh more on average. Brown bears are more aggressive and less willing to flee from a threat than black bears

Threats to Black Bears

merican black bears adapt well to human development, and their global population is estimated to be twice that of all other species of bears combined. While they are not threatened at this time, individual bears often come into conflict with humans. Because of their adaptability, they can live in close proximity to human development. Particularly in years when the local berry crop fails, they will frequent municipal garbage dumps and household garbage cans looking for food. Once they become habituated or begin to be seen as a threat to people or pets, they can be relocated or even killed by wildlife authorities.
