From the website:
Artwork should highlight one or more land- and/or ocean-dwelling endangered species—mammal, bird, reptile, amphibian, fish, plant, and/or invertebrate (e.g., insect, spider, snail, coral, crustacean or clam)—found in the United States. Entrants are encouraged to depict species found in their region, ideally in the species’ usual habitat. Entrants may wish to choose from the U.S. Fish and Wildlife Service’s Spotlight Species. (See: http://www.fws.gov/endangered/ for a list of all endangered species.)
Winners will be chosen from 4 age categories. Prizes include a trophy and a round-trip flight to a reception in Washington, D.C. and art supplies. Visit the website for more details and requirements.
Entries must be postmarked by March 15!
