The American black bear (Ursus americanus) is North America’s most common and widely distributed bear species. These adaptable omnivores range from 1.2 to 2 meters (4 to 6.6 feet) in length and weigh between 40 and 300 kilograms (88 to 661 pounds). Males typically grow larger than females.
The Distribution of Black Bears Across the United States
Black bears are present in at least 40 of the 50 U.S. states. Historically, they ranged across most forested regions of North America, and their populations are robust in many places today.
In the Northeast, black bears maintain a continuous range throughout New England, including states like Maine, Massachusetts, Vermont, New Hampshire, and Connecticut. Maine, for instance, boasts one of the highest black bear populations in the region, with estimates between 24,000 and 36,000 individuals. Further south in the Mid-Atlantic and Southeast, populations become more fragmented, often restricted to the Appalachian mountain chain or coastal areas. States such as Virginia, Georgia, Florida, Louisiana, Mississippi, Kentucky, and Missouri have established populations, with Louisiana being home to a distinct subspecies, the Louisiana black bear.
Moving into the Midwest, states like Michigan, Minnesota, and Wisconsin support substantial black bear numbers. Minnesota hosts an estimated 12,000 to 15,000 bears, while Wisconsin’s population exceeds 24,000, primarily in the northern forested regions.
The western United States is also a stronghold for black bears, with Alaska having the largest population in the country, exceeding 100,000 individuals. California holds the largest population in the lower 48 states, estimated between 30,000 and 40,000 bears, found across its diverse landscapes from the Sierra Nevada to coastal forests. Other western states like Colorado, Idaho, Montana, Oregon, and Washington also have thriving populations, often concentrated in mountainous and forested areas.
Conversely, states such as Delaware, Hawaii, Illinois, Indiana, Iowa, Kansas, Nebraska, North Dakota, and South Dakota either lack breeding black bear populations or experience only rare sightings.
Understanding Black Bear Habitats
Black bears prefer environments that provide essential resources. They are most commonly found in forested areas, including deciduous, coniferous, and mixed forests, which offer dense cover and ample food sources. These environments also provide suitable locations for denning, especially during winter.
Beyond forests, black bears also inhabit mountainous regions and swamps, utilizing the varied terrain for foraging and shelter. Their omnivorous diet allows them to adapt to seasonal changes in food availability. In spring, they consume emerging plants, insects, and carrion. Summer brings an abundance of fruits and berries, which become a significant part of their diet, supplemented by nuts, insects, and occasional small mammals or fish. As fall approaches, bears focus on consuming high-calorie foods like nuts and fatty fruits to build up fat reserves in preparation for their winter denning period.
Coexisting with Black Bears
Living in or visiting areas with black bears requires understanding how to minimize potential conflicts. Black bears are naturally wary of humans, but they can become accustomed to human presence and food sources, leading to increased interactions. To prevent bears from associating human dwellings with food, it is important to manage attractants around homes and campsites.
Securing garbage in bear-resistant containers or storing it indoors is a primary step, along with removing outdoor pet food and cleaning barbecue grills after use. Bird feeders should be removed, especially from late March through November, and any spilled seed should be promptly cleaned.
If a black bear is encountered, remaining calm is important. It is advised not to run, as this can trigger a chase response. Instead, individuals should make themselves appear large, make noise, and slowly back away to allow the bear an escape route. In the rare event of a physical attack by a black bear, fighting back is the recommended response.
