Gyaros, a Greek island with a dark and violent past as a military prison and naval firing range, has emerged as a sanctuary for rare Mediterranean monk seals. The island's isolation, combined with its history of human absence, has created an ideal environment for these seals to thrive. The discovery of a colony of around 70 adult seals on the island, along with the presence of Yelkouan shearwaters, highlights the importance of preserving such habitats. However, the island's delicate balance is under threat from illegal fishing, introduced predators, and political pressures. The need for a comprehensive plan to manage the island's resources and protect its unique ecosystem is crucial to ensure the long-term survival of these species.
