Habitat: Dall island is mainly forested with a peak elevation of 745 metres and a total land area of 657.9 km².
Status: Not known.
Life span: Assumed to be between 20 and 30 years in common with most other black bears.
Food: Omnivorous with a diet comprising vegetation, berries, pine nuts, insects, likely small mammals and carrion when found. Salmon during the spawning run. May also take fish from lakes.
Behaviour: The bears typically hibernate for up to five months, most commonly emerging in April or May. Pregnant females give birth in the den, usually to two or three cubs in January or February. They will remain with their mother for about one and a half years, during which time she will not become pregnant again.
Threats: It seems likely that the greatest threats to these bears are the logging and limestone quarrying industries.
