Pine Barrens Tree Frog 294 by Andy Warhol is a work included in the artist’s 1983 Endangered Species complete portfolio. It depicts the amphibious Dryophytes andersonii, a tree frog indigenous to three distinct regions of the United States: New Jersey, specifically the Pinelands or Pine Barrens from which it gets its name, the Sandhills of North and South Carolina, and parts of lower Alabama and the Florida panhandle. It’s notable for being one of the four animals included in the Endangered Species series that is no longer considered endangered or vulnerable. The tree frog was considered threatened between 1977 and 1983; however, its status was changed after stable populations were found in the aforementioned areas in Florida.
