Birds: Several bird species eat the hips including grouse, bluebirds, juncos, grosbeaks, quail, pheasants, and thrushes. The seeds are using by birds as a source of grit. Rose thickets are an important shelter and habitat for birds such as pheasants and grouses.
Insects: The leaves are eaten by mourning cloak butterfly larvae. The leaves are used by the leaf-cutter bee. Young rose shoots are popular with aphids which in turn provide food for a wide range of predators including ladybugs and songbirds.
Mammals: Mammals that eat the hips include chipmunks, rabbits, hares, porcupines, coyotes, deer, elk, and bear. The Rose thickets provide important shelter and habitat for many mammal species.
