The population now numbered between 1,500 to 2,000, said Linda Cayot, a scientific adviser to Galápagos Conservancy. “During the expedition we found nests, recently hatched tortoises, and adults born on Española, which indicates that the tortoise population is doing well.” Preliminary results of the survey, conducted over 10 days by 24 wardens from the Galápagos national park authority, found that albatross, cactus and woody vegetation had also partly recovered, restoring the island to something akin to what Darwin saw two centuries ago.Ī giant tortoise ( Geochelone hoodensis) population that in the 1970s had dropped to about 15 was once again a common sight on the island, said Washington Tapia, a park official who led the survey, which used electronic devices to track the animals. “It’s a great end to a sad story,” said Johannah Barry, president of Galápagos Conservancy, a Virginia-based organisation which partly funded the study. The project aims to turn the clock back to before human beings all but wiped out a species that helped to inspire Charles Darwin’s theories on evolution and natural selection. Scientists have successfully reintroduced giant tortoises to a Galápagos island where the species once teetered on extinction, raising conservation hopes for the rest of the archipelago.Ī survey of Española, the southernmost island, confirmed last week that a pioneering effort to repatriate giant tortoise hatchlings has produced a thriving, reproducing population of more than 1,500 specimens.
