Black Bears in Canada: Ecology, Attitudes, and Management
This paper examines black bears (Ursus americanus) in Canada, covering their ecology, distribution, behavior, and diet. It reviews population estimates across North America and Ontario, describes denning and reproductive habits, and discusses the growing problem of food-conditioned bears in human communities. The paper then surveys research on public and hunter attitudes toward black bears, identifying demographic and experiential factors that shape positive or negative perceptions. Finally, it considers wildlife management strategies—including relocation and lethal control—and the broader challenge of human-wildlife conflict as human populations expand into natural landscapes and local residents increasingly interact with conservation institutions.

What makes this paper effective
- Grounds ecological claims in specific quantitative data (population estimates, home range sizes, weight ranges), giving the paper empirical credibility.
- Synthesizes multiple peer-reviewed sources to present a nuanced picture of how demographic variables—age, gender, rural residency—influence attitudes toward bears.
- Connects biological facts about bear behavior directly to management implications, showing a coherent argument from ecology to policy.
Key academic technique demonstrated
The paper demonstrates effective use of source synthesis: rather than citing one authority per claim, it stacks multiple studies (e.g., Teel 2002 alongside Williams 2002) to note where findings agree or conflict, giving the literature review intellectual honesty and depth.
Structure breakdown
The paper opens with taxonomy and range data before moving into ecology (diet, size, home range, hibernation). It then transitions to social dimensions—first describing the conflict created by food-conditioned bears, then surveying attitudinal research across different publics. The final section addresses management responses and the political tension between local residents and conservation institutions, bringing the ecological and social threads together.
Overview of Black Bears in Canada
Globally, there are eight bear species in the family Ursidae (Order Carnivora), three of which are found in Canada: the black bear, the brown bear, and the polar bear. Black bears still occupy 85% of their historic Canadian range and 62% of the original North American range (Kolenosky and Strathearn 1987; Pelton 2000).
In North America, black bears evolved as forest dwellers, and most populations are currently stable or increasing (Brown, 1999; Pelton, 2000). The population throughout North America is currently estimated at 750,000 animals, while the Ontario population approximates 75,000–100,000 animals, with the highest densities found in the central and north-western regions of the province (Smith and DeAlmeida 1990; Anonymous 2006b).
Diet, Size, and Behavior
The diet of bears consists mainly of plants, berries, and animals such as caribou and moose calves. Bears can weigh up to 600 lb. (272 kg), but most commonly males weigh 200–300 lb. (90–136 kg) and females are smaller at 110–180 lb. (50–82 kg). Black bears have large home ranges in Newfoundland and Labrador — males 200 km² or more, and females approximately 60 km² — which has made efforts to understand and manage their relationship with caribou particularly challenging.
Throughout the winter, black bears hibernate in dens that they make in sheltered spots such as caves, brush piles, burrows, or tree cavities (Powell, 1997). Females give birth to 2–3 cubs in mid-winter and remain in the den with the cubs until spring. The cubs generally stay with their mothers for two years.
Human-Bear Conflict and Food Conditioning
Black bears are most active during dawn and dusk and are fairly timid except when human food is available (Department of Environment and Conservation, 2009). It is common to find black bears in communities once they have located a food source. Bears that become comfortable around humans are described as habituated, meaning they have lost their natural fear of humans, which can make them dangerous as they search for food. Food-conditioned bears are an increasing problem in the United States and Canada (Decker and Chase, 14–51). As the black bear population increases, human-wildlife interactions will inevitably increase as well (Treves and Karanth, 383–396).
Conclusion: Conservation and Community
In the past, the response to human-wildlife conflict has been to kill the species and destroy their habitat (Manfredo, 2008). How a person is affected by human-wildlife conflict is related to how they value the particular wildlife involved, since conflict arises from differences in values. The movement toward non-utilitarian perspectives has shifted human-wildlife conflict from a contest between people and wildlife to one between people and institutions. For example, local residents can feel resentment toward conservation initiatives or hold negative views toward managers because of impacts caused by wildlife, and may resist management options that do not impose some form of direct control (Treves, 383–396).
