Native to both Newfoundland and Labrador.
Usually found on slow moving streams, ponds, lakes and rivers. Beavers alter their environment to suit their needs by building dams to maintain a constant water level for lodge construction and easy access to underwater food supply.
Beavers are found throughout Canada, mostly in forested areas but sometimes in the tundra or near deepwater sources surrounded by deciduous trees.
Beavers eat mainly during the night since beavers are nocturnal. Typical foods include bark, leaves, twigs, buds of deciduous trees, aquatic vegetation and lily roots. Beavers prefer maple, aspen, birch, poplar, willow and alder. Before winter, the whole beaver colony gathers food. They make a cache of their favorite woody foods and place them in deep water near the lodge.
Wolves, coyotes, bears, lynx and wolverine have been known to prey on beavers. Otters can sometimes get into the lodge and kill the kits; however, an adult usually stays with the young for protection.
The average lifespan of beavers is 5 - 7 years in the wild. The oldest recorded in NF was 19 years.
A beaver's pelt is a rich brown color, with a characteristic flat tail which acts as a mechanism to frighten predators and a prop for balance when working on land; they have continuously growing orange front teeth and large rounded shape.
Beavers are monogamous (choose a single mate) animals. They breed in February and gestation takes about 110-120 days (4 months). They only produce one litter per year which consists of an average of three kits. Females can begin breeding at 32 months ( about three years). Kits leave the colony at 2 years of age.
Average weight for an adult beaver is (40 - 60 lbs)(18 - 27 kg). May measure up to (4 ft)(1.3 m) long (including the tail).
