Amphibians

Eight amphibian species are present in the Province of Newfoundland and Labrador.

  • Four species, including American Toad, Mink Frog, Green Frog and Wood Frog, are found in Newfoundland.
  • Seven species, including Two-lined Salamander, Blue-spotted Salamander, American Toad, Mink Frog, Wood Frog, Northern Leopard Frog, and Spring Peeper are native to Labrador.
  • All amphibian species in Newfoundland are exotic. 
  • Green Frogs are only found in Newfoundland.

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.
