The Charles Darwin Foundation is home to the largest Natural History Collections of endemic, native and introduced species of Galapagos in Ecuador, with more than 135,000 specimens and 7,500 species across four Collections: Marine, Vertebrate, Terrestrial Invertebrate and a Herbarium.

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.

You can support our research and conservation projects by adopting one of the Galapagos species.

By adopting a Galapagos giant tortoise, you will contribute to our research and outreach activities related to various tortoise species. The Galapagos tortoises have become threatened largely due to habitat change and fragmentation, climate change, diseases, and introduced species. The Charles Darwin Foundation leads a multi-institutional project that aims to determine movement behavior, assess health, and describe the ecological role of tortoises in the Galapagos ecosystems.

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.

Giant tortoises are emblems of Galapagos. They are critical ecosystem engineers and they are also important for the local economy. Yet all 12 species of Galapagos Giant Tortoises are of conservation concern. Our work focuses on conserving these gentle giants through research and education.

More than half of the endemic plant species in Galapagos are currently classified as threatened. The potential loss of these imperiled species not only disrupts ecosystem integrity, but also jeopardizes the survival of iconic native fauna that depend on it. We are updating the IUCN Red List of endangered plant species of Galapagos in order to enable targeted species conservation actions.
