Common Greenbrier
or
Catbrier
Smilax rotundifolia
Numerous birds and animals eat common greenbrier fruits. The persistent
fruits are an important late winter and early spring food for wintering
birds including northern cardinals and white-throated sparrows.
White-tailed deer and lagomorphs browse the foliage.
Common greenbrier forms impenetrable thickets of prickly branches which
probably create good cover for small mammals and birds.
