The challenge
The islands of the South Cyclades, including Zafora, Dyo Adelfia, and Tria Nisia, are ancient ecosystems with exceptional biodiversity, often referred to as the “Galapagos of the Mediterranean.” These islands host rare and endemic species – relict Ice Age plants clinging to cliffs, flightless beetles, and unique invertebrates – evolved over millions of years in isolation. However, their survival is now at critical risk due to invasive goats and sheep, introduced under outdated livestock agreements. Overgrazing has stripped vegetation, leading to soil erosion, desertification, and habitat loss, pushing these fragile species toward extinction. If action is not taken, we risk losing millions of years of evolutionary history.
The solution
In order to restore and protect these unique ecosystems, the removal of the invasive species is necessary. The team of Dr. Johannes Foufopoulos of University of Michigan proceeded to the removal of goats and sheep. Such practices have been proven successful in similar ecosystems, leading to vegetation recovery, soil regeneration, and biodiversity revival. Such solutions require the collaborative effort of multiple stakeholders such as the effective involvement of the Municipality of Astypalea, local shepherds, environmental researchers, and other community stakeholders. CPF managed to support the collaboration of the above.
Activities
This project is a result of different activities such as:
- Targeted Removal of Invasive Livestock
- Community Collaboration & Outreach
- Scientific Monitoring & Ecological Assessments.
- Policy Reform & Future Prevention.
By restoring these fragile ecosystems, we protect some of Europe’s rarest species and ensure that future generations can witness the ecological richness of the South Aegean’s Galapagos.
About the Grantee
Johannes Foufopoulos, PhD and Associate Professor of the University of Michigan, focuses his lab research on fundamental conservation biology questions and on issues related to the ecology and evolution of infectious diseases.
What you can do
- Support CPF to continue establishing collaboration with international academia for the protection of Greek Islands and their unique biodiverity.
- Stay tuned, for the next phase of the project. In 2026 the team of Dr. Foufopoulos will return to measure the impact of the species removal.
