Our work
Our research aims to emphasize the importance of the Amvrakikos Gulf as a critical habitat for sharks and rays, shedding light on their behavior, their population health, and the challenges they face. This is not just about science—it is about making a tangible difference. Through your efforts, you’ll help us raise awareness of the National park’s ecological value, driving meaningful actions to protect and preserve one of Greece’s most extraordinary natural wonders.
Whether you are passionate about marine life, eager to support environmental sustainability, or simply looking to be part of an inspiring cause, this is your chance to make a lasting impact.
Amvrakikos Wetlands National Park
Amvrakikos Wetlands National Park stands as one of Greece’s most important ecosystems, renowned nationally and internationally for its extraordinary biodiversity and ecological value. Home to over 295 bird species, including migratory and rare species, as well as the highest density of bottlenose dolphins in the Mediterranean, a vast amount of sea turtles, and unique aquatic birds, including the second largest colony of Dalmatian pelican in Greece, the park offers a glimpse into a rich and vibrant natural world. Its priority habitats—spanning lagoons, river estuaries, riparian forests, and the unique semi-enclosed bay—are a testament to its unparalleled diversity.
The bay’s natural wealth has supported human activities since ancient times, from the grandeur of Nicopolis to today’s agriculture, aquaculture, and tourism. However, these activities also pose significant pressure on its resources. Balancing sustainable development with the conservation of this extraordinary ecosystem and the resilience of its coastal community that highly depends on the Amvrakikos Gulf is a critical challenge.
Sharks and Rays in Amvrakikos
Since February 2022, iSea has been diving deep into the unique marine ecosystem of Amvrakikos Gulf through the By ElasmoCatch Project. This ongoing research has revealed the Gulf’s vital role as a hotspot for elasmobranch biodiversity, hosting an incredible array of species, including eight species of rays and two shark species. Among these are some of the most threatened in the Mediterranean, like the Critically Endangered Spiny Butterfly Ray and the Duck Bill Eagle Ray, alongside species, such as the Endangered Sandbar Shark and several others, classified as Vulnerable or Data Deficient.
Even more exciting, the Gulf has been confirmed as a nursery ground for three key species—the Spiny Butterfly Ray, Duck Bill Eagle Ray, and Smooth-hound Shark—with newborns and juveniles observed year-round. This makes the area a lifeline for these species, offering a critical habitat to support their survival.
However, the delicate balance of this ecosystem is under threat. Fishing activities in the area, including both targeted and accidental bycatch, disproportionately affect immature individuals, potentially harming future populations. Our research has shown that fishing gear plays a significant role, with certain nets catching younger and smaller individuals, while others target large, vulnerable species during critical times, such as pregnancy. At the same time pollution, that is the main threat of the Gulf, also affects shark and ray populations.
Beyond fishing pressures, the populations of sharks and rays in the Amvrakikos Gulf face significant threats from agricultural and industrial activities. Runoffs from intensive agriculture introduces high levels of nutrients, pesticides, and other chemicals into the water, leading to pollution that can degrade critical habitats, like nursery grounds. Industrial waste, including untreated or poorly managed discharges, adds further stress to the ecosystem by contaminating the water with harmful substances.
Inner Ionian Archipelago
The Inner Ionian Archipelago is of high ecological value due to the presence of a significant number of marine megafauna species, as well as the existence of extensive Posidonia seagrass meadows. The distinctive morphology of the area, characterized by the presence of numerous submerged caves, provides critical breeding habitats for the Mediterranean monk seal and hosts other marine mammal species, such as the Cuvier’s beaked whale, the fin whale, the common dolphin, and the common bottlenose dolphin. Two species of sea turtles also occur in the area, the loggerhead turtle and the green turtle, together with several marine and pelagic bird species, such as the Yelkouan shearwater, Scopoli’s shearwater, the European shag and two deep-sea shark species including the Endangered devil ray.
The area remains particularly important for the Mediterranean monk seal, with indications of an increasing presence in recent years, particularly around Formicula islet. The increased frequency of sightings, including newborn pups, highlights the importance of the area as a critical habitat, while simultaneously underscoring the need to manage pressures from unregulated tourism. Similarly, the uninhabited islets of Atokos and Arkoudi are of comparable ecological significance.
Formicula
Formicula is a small uninhabited islet in the Inner Ionian Archipelago, covering just 8.7 hectares yet hosting remarkable biodiversity. Its surrounding marine habitats include rocky reefs, Posidonia seagrass meadows, underwater caves, and sandy bottoms, supporting a rich variety of marine life. These habitats are home to threatened species, such as groupers and the Mediterranean monk seal, one of the world’s most endangered mammals.
A major step for the protection of the area was the establishment of a 200-meter strict protection zone, following a recent Ministerial Decision that was issued after 3 years of intense efforts of iSea. Despite these measures, significant threats remain. Unregulated tourism and increased boat traffic disturb wildlife, particularly the Mediterranean monk seal, while uncontrolled anchoring damages sensitive Posidonia meadows. Illegal fishing practices continue to impact the ecosystem, underscoring the need for ongoing monitoring and public engagement.
