Green Sea Turtles of Guinea-Bissau: Protecting Africa’s Turtle Islands
Guinea-Bissau: A Sanctuary for Green Sea Turtles
Did you know that many African islands are known as "Turtle Islands"? These remarkable places serve as critical nesting grounds for green sea turtles, and one of the most significant of these is found in Guinea-Bissau, a small West African country. The João Viera-Poilão Marine Park here hosts the largest green sea turtle nesting site on the entire Atlantic coast of Africa. However, despite the country's critical role in turtle conservation, challenges remain in ensuring their protection.
A Rich History and Biodiversity
Guinea-Bissau may be small, but its cultural and natural significance is immense. Just south of Senegal, this coastal nation is home to the Bijagos Archipelago, a group of 88 islands, 23 of which are inhabited. These islands have been a protected Biosphere Reserve since 1996, making them a rare example of an African marine ecosystem that is internationally recognized for conservation.
The country’s history is marked by its connections to the Mali Empire and its later involvement in the Portuguese slave trade. It wasn’t until the early 20th century that the interior was explored, met with significant resistance from indigenous populations. Today, this heritage is reflected in the local languages and a unique dialect of Crioulo.
The Green Sea Turtle’s Epic Journey
Green sea turtles, which can grow up to 1.5 meters (5 feet) and weigh more than 300 kilograms (700 pounds), are one of the ocean’s most awe-inspiring creatures. Every year, they make long migratory journeys to the Bijagos Archipelago, traveling as much as 2,600 kilometers (1,600 miles) to reach their nesting grounds in Guinea-Bissau. This amazing migration highlights the importance of preserving these areas, where the turtles return year after year to lay their eggs.
As they nest, green sea turtles face significant threats—from human interference to habitat destruction. This is why Guinea-Bissau has strict laws that protect these endangered creatures, making it illegal to harm, collect, or kill green sea turtles. These laws are part of a broader effort to maintain the country’s biodiversity, including the protected marine areas of João Viera-Poilão and Orango.

The Bijagos Archipelago: A Haven for Wildlife
In addition to its turtle populations, the Bijagos Archipelago is home to another environmental treasure: migratory birds. The archipelago ranks as the second most important site for migratory birds in West Africa, after the Banc d'Arguin in Mauritania. These birds find sanctuary in the Community Urok Marine Protected Area, where they breed and overwinter.
Today, these islands are gaining attention from tourists, particularly those interested in wildlife and beach tourism. However, as tourism increases, so does the challenge of balancing economic development with the need to preserve these fragile ecosystems.
Green Sea Turtle Facts You Should Know
Size and Strength: Green sea turtles can grow up to 1.5 meters (5 feet) and weigh over 300 kilograms (700 pounds), making them the largest of the hard-shell sea turtles.
Longevity: These turtles have an impressive lifespan of 80 years or more in the wild, making them true survivors of the oceans.
Diving Skills: Green sea turtles can stay underwater for up to five hours, although their typical feeding dives last only five minutes or less.
The Ongoing Fight for Conservation
Despite the legal protections in place, green sea turtles in Guinea-Bissau still face numerous threats. Habitat destruction, climate change, and illegal poaching continue to jeopardize their future. As consumers, we can play a role by supporting sustainable tourism and advocating for stronger environmental protections worldwide. Guinea-Bissau's turtle sanctuaries are more than just a natural wonder—they are a crucial piece of the global conservation puzzle.
