Two groundbreaking studies led by Stephen Blake, Ph.D., assistant professor of biology at Saint Louis University and Sharon L. Deem, DVM, Director of Saint Louis Zoo Institute for Conservation Medicine, in collaboration with the Charles Darwin Foundation (CDF) and teams of multidisciplinary scientists shed light on crucial aspects of the conservation of two critically endangered giant tortoise species endemic to the Island of Santa Cruz, Chelonoidis porteri and Chelonoidis donfaustoi. Both studies offer valuable insights into the challenges these emblematic species face and the strategies needed to ensure their survival in the face of potential future habitat alteration and climate change.

Discover the mission, vision, and impact of the Charles Darwin Foundation. Dedicated to preserving the Galapagos Islands through groundbreaking scientific research and conservation initiatives since 1964.

In Galapagos, 83% of the landmass falls within the arid zone. Restoring plant communities in this zone is challenging and slow, and natural regeneration in severely degraded areas is very limiting. Our scientists work to restore the arid habitat across various islands in the archipelago, notably Baltra Island, which has undergone significant human alteration, and special use sites such as garbage dumps and quarries on inhabited islands.
