Brown bears reproduction and life cycle
Female bears can den when they are pregnant and they usually give birth to 1 or 2 cubs during winter rest. A female brown bear can give birth to cubs every 3 years because these cubs must stay with their mother for about 2 and a half years until they get independent. This is one reason that affects their numbers and their life expectancy.
Young bears are very vulnerable and this is one of the main reasons why the average age of brown bears is relatively low. The only positive thing is that these cubs grow quite fast and they usually have about 55 lbs when they are 6 months old. They keep growing until they reach 10 or 11 years.
