Pine Barrens tree frog
Dryophytes andersonii

The Pine Barrens tree frog (Dryophytes andersonii ) is a species of New World tree frog. It is becoming rare due to habitat loss.


Dryophytes andersonii, only about 1–3 inches (25–76 mm) long, is one of the smaller species of tree frogs. Members of the species are predominantly green, with wide, dark stripes. They often have spotted, orange-gold markings on the hidden surfaces of their legs and tend to have large toe pads.

The key to distinguishing the Pine Barrens tree frog from the similar-appearing American green tree frog (D. cinerea ) is the white-bordered lavender stripe on each side of the body in the Pine Barrens tree frog. D. cinerea has only a white stripe in this location.

Biogeographical realms

Dryophytes andersonii is most commonly found in brushy areas, often near peat bogs or shallow ponds. They usually inhabit areas carpeted with thick moss. Adults are terrestrial, but tend to reside near water sources. Unlike most frogs, they are tolerant of low pH levels, and often lay eggs in shallow, acidic ponds. The ideal pH level for D. andersonii eggs is between 3.8 and 5.9.

Due to the limited extent of suitable habitats, Dryophytes andersonii is currently distributed in three disjunct areas in the southeastern United States: the New Jersey Pine Barrens; the Sandhills of North and South Carolina; and the Florida panhandle and southern Alabama. Although one specimen of D. andersonii is known from Georgia, a population is not known to currently exist there.

Dryophytes andersonii is the state frog of North Carolina.
