American Bullfrog & Brown Tree Snake

American Bullfrog & Brown Tree Snake

The American bullfrog and Brown Tree Snake cost the world economy $16 billion, as per the study.

  • The invasive duo has caused ecological damage in addition to ruining farm produce and causing expensive power interruptions.
  • More than two million Brown Tree snakes populate the tiny Pacific Island, with one estimate calculating as many as 20 inhabitants per acre of Guam's jungle.
  • The Brown Tree snakes have the most significant impact on Pacific islands, and the amphibian breed of the American bullfrog multiplied uncontrollably in Europe.

About the Species

  • The brown-and-green frog known as Lithobates Catesbeianus which can weigh over 2 pounds (0.9 kilos), had the greatest impact in Europe.
  • The brown tree snake, or Boiga irregularis, has multiplied uncontrollably on Pacific islands including Guam and the Marianna Islands, where the species was introduced by U.S. troops in World War II.
  • The snakes have at times been so abundant that they caused power outages by crawling on electrical equipment.
  • This signals the need for investment in controlling the global transport of invasive species to avoid paying for mitigation after the invasions occur.
