Hold the Press! 'Extinct' Galapagos Giant Tortoise Found on Isabela
This week, researchers led by a team from Yale University have reported that there is a strong possibility that the Floreana tortoise (Chelonoidis elephantopus) may well still be surviving - on Wolf Volcano in the northern part of Isabela.
The Floreana tortoise was thought to have become extinct 150 years ago, soon after Darwin's famous Beagle voyage. In the 18th - 19th centuries, island visitors including pirates and whalers had a heavy impact on tortoise numbers but also moved tortoises between the Islands, most likely as a portable food source. This has now resulted in a mix of different populations in areas like Wolf Volcano that were a popular stop off point with sailors.After a small number of hybrid tortoises were discovered on Wolf Volcano, a study was launched in 2008 to collect blood samples from the tortoise population in order to analyse the DNA and establish the various origins of the tortoises. After some dedicated fieldwork, 1,669 individuals were sampled.
It has been reported this week that 84 of these tortoises were found to be hybrids with an extremely high possibility that one parent was a pure bred Floreana tortoise. 30 of these individuals were under 15 years old suggesting that it is highly likely that there is at least one pure bred Floreana tortoise still wandering around on Wolf Volcano!
The Galapagos National Park is now set to embark on a rescue mission for the Floreana tortoise - a task that could never have been predicted at the beginning of Project Floreana (a key project funded by GCT). Stay tuned for updates on this exciting news!
