History of Isla Isabela


JuteVilla
Isabela is also interesting for its flora and fauna. The young island does not follow the vegetation zones of the other islands. The relatively new lava fields and surrounding soils have not developed the sufficient nutrients required to support the varied life zones found on other islands. Another obvious difference occurs on Volcan Wolf and Cerro Azul; these volcanoes loft above the cloud cover and are arid on top.
Isabela's rich animal, bird, and marine life is beyond compare. Isabela is home to more wild tortoises than all the other islands. Isabela's large size and notable topography created barriers for the slow-moving tortoises; apparently the creatures were unable to cross lava flows and other obstacles, causing several different sub-species of tortoise to develop. Today, tortoises roam free in the calderas of Alcedo, Wolf, Cerro Azul, Darwin and Sierra Negra.
Introduced goats multiplied to over 100,000 but were eradicated by the Ecuadoran government.
Other noted species include penguins, cormorants, marine iguanas, boobies, pelicans and Sally Lightfoot crabs abound. Galapagos Land Iguanas and Darwin's finches, Galápagos Hawks, Galápagos Doves and very interesting lowland vegetation. The west coast of Isabela in the Bolivar Channel is the best place in Galapagos for viewing whales and dolphin
