Of these, around 1,000 are found in the Northern Continental Divide in northwestern Montana. Except for females with cubs,[47] grizzlies are normally solitary, active animals, but in coastal areas, grizzlies gather around streams, lakes, rivers, and ponds during the salmon spawn. Opinion Columnist. Pregnant females give birth in the dens and nurse their cubs until they are large enough to venture outside in the spring as snow melts and new food become available. Omnivorous animals, grizzlies feed on berries, plant roots and shoots, small mammals, fish, calves of many hoofed animals, and carrion.

Coastal areas host the highest population densities year round because there is a larger variety of food sources available, but Brooks Camp hosts the highest population (100 bears). These can include blueberries, blackberries (Rubus fruticosus), salmon berries (Rubus spectabilis), cranberries (Vaccinium oxycoccos), buffalo berries (Shepherdia argentea), soapberries (Shepherdia canadensis), and huckleberries (Vaccinium parvifolium), depending on the environment.

[171] To date, most corridors are found to be infrequently used, and thus genetic isolation is currently occurring, which can result in inbreeding and therefore an increased frequency of deleterious genes through genetic drift. [54] Females live longer than males due to their less dangerous life; they do not engage in seasonal breeding fights as males do. Large adult grizzlies may be about 2.5 metres (8 feet) long and weigh about 410 kg (900 pounds).
