During the 1960s, several amphibian species were introduced to the Island of Newfoundland, including American Toads, Wood Frogs, Striped Chorus Frogs, and the Northern Leopard Frog. The Striped Chorus Frog and the Northern Leopard Frog were unable to establish on the island.
American Toads have been successful on the west coast, and have been transplanted on the Avalon Peninsula and in Central Newfoundland. Wood Frogs are now well established in the Corner Brook area (Maunder, 1997). Mink Frogs have also been found on the island.
