Study reveals urgent need for large scale invasive species management to prevent extinction of endemic forest in the Galapagos Islands

For 26 years, scientists have returned to the misty highlands of Santa Cruz to track the impacts of the invasive quinine and of the management actions. The continuous control of invasive plants resulted in the remarkable recovery of endemic plant species, especially that of the iconic Miconia robinsoniana. This is the story of endurance, restoration, and how a long-term commitment can strengthen conservation actions to protect the Galapagos ecosystems.

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.

While a mere 3% of the Galapagos Islands are home to people, our presence in this small fraction of the archipelago has put the native vegetation at risk. Our restoration program in urban and rural areas engages the local community in conservation and restoration efforts to secure the long-term health of these unique ecosystems.

At the Charles Darwin Foundation, we believe that sustainable conservation depends on the involvement of the local community. Our goal is to inspire future generations of local conservation leaders, and embed conservation and sustainable development in the local culture.
