Picture shows an early season (May 22nd) willow along the Twitter Creek Floodplain which was food for moose over winter. Small shoots radiating from the limbs display the results of browsing moose.

Many species including willow are important to the moose diet, which varies from winter to summer.

In winter, moose eat birch (Betula papyrifera), lowbush cranberry (Vaccinium vitis-idaea), willow (Salix spp.), alder (Alnus spp.), and and foliose lichens (Peltigera spp.).

In summer, moose east birch (Betula papyrifera) and a variety of forbs, grasses, sedges and aquatic plants, as well as willow (Salix spp.).
