Beaver Diet

In March and April, beavers consume a lot of tree bark, but come summer, approximately 90 % of a beaver’s diet consists of grasses, aquatic plants, and other herbaceous vegetation.  Of the woody plants that they do eat during the warmer months, aspen/poplar (in photograph) and willow are favorites.  It appears that beavers use their sense of smell in order to find their tree of choice.  The greater the distance from the pond, the more selective beavers are in terms of species chosen – they go as far as a tenth of a mile away and up steep slopes for aspen!
