Everything was looking up for the tortoises of the Galapagos Islands. Until the goats arrived.
Take Home Message: Invasive species wreak havoc on islands, and the goats of the Galapagos were no exception. A controlled hunt was able to successfully eliminate goats from the Galapagos by 2006, protecting the Galapagos tortoise and other native species. While islands are the most susceptible ecosystems to invasive species, their small size makes eradication efforts feasible. You can help to stop the global spread of invasive specie: plant native species in your garden, avoid exotic pets and plants, and volunteer with conservation organizations.
