Project Isabela

ecological devastation to the islands and posed as a threat to the Galápagos tortoise that was by the 1990s near extinction. By 1997, plans had been officially implemented to eradicate these introduced species in northern Isabela, Santiago, and Pinta islands.^[2][3] Skilled park rangers used helicopters to hunt and sterilized Judas goats, fitted with radio collars to track down the feral goats.^[1] The initiative was brought into action in 1999, and by 2006, 150,000 goats alone were eradicated. As of 2011, the project was the world's largest ecological island restoration effort ever.^[2][3]
