A network of West Africa Marine Protected Areas (MPAs) covers key areas used by green turtles, new research reports.

The RAMPAO system operates along the coasts of seven countries, from Cape Verde to Sierra Leone, avoiding critical habitats for a variety of reasons.

The new study followed 45 female green turtles from Poilão Island, in Guinea-Bissau’s Bijagós Archipelago, which hosts the largest population in the Eastern Atlantic.

The turtles were found to spend most of their time sleeping and feeding in the MPA system.

However, only 21% of migration corridors are protected.

The study was conducted by a partnership with the University of Exeter (UK), MARE – ISPA, Instituto Universitário (Portugal), the Institute of Biodiversity and Protected Areas (Guinea Bissau) and the Banc d’Arguin National Park (Mauritania). ). In addition, young people from the villages of Bijagós took part in labor activities.

“RAMPAO is an excellent example of an MPA system, with good relationships between MPAs and strong links between the organizations that maintain them,” said Drs. Rita Patrício, of the Center for Ecology and Conservation on Exeter’s Penryn Campus in Cornwall, and MARE.

“West Africa has a very rich ecosystem. It has already begun to take care of important habitats, such as the sea, mangroves, estuaries and intertidal fences, which are used by large coastal populations and with seabirds, and charismatic species such as humpback dolphins. ”West African manatees and green turtles.

“Our study is part of a broader experiment to see where the species are spreading in the country, to find the best ways to prevent them.

“Green turtles have a hard time, which is about moving between feeding grounds and feeding grounds.

“It is important to understand the relationship between these areas, compare the level of protection, and ensure that maintenance activities at production sites are not interrupted due to the lack of protection at the production sites. feeding ground, and vice versa.

“In the case of green turtles, our research shows that the MPA system on land covers all the marine areas used during nesting as well as most of the feeding areas as well. this is a great motivator.

“Our finding that most of the major routes used by turtles now fall outside the MPA system suggests it’s an opportune time to increase protection.”

During the nesting period, the turtles spent an average of 95% of their time within the limits of the MPA system, and among the 35 turtles that had good results during feeding, 28 of them used water in MPAs.

Close to the coast are important hiking trails, where the country’s important fishing activities can strengthen the coastline.

Dr. According to Patrício, most of the green turtles in this country are “watchful” -they are “careful”.

“If you open up conservation, the population can drop quickly,” he said.

The United Nations goal to cover 10% of the world’s oceans by 2020 has not been met, but the coverage of protected areas is increasing – and there are now phones to protect it. more than 30% of the ocean by 2030.

Balancing marine protection with the needs of marine communities is important, and Dr. Patricio said the ultimate goal is to bring all parties together to improve care in a way that is conducive to people and the ecosystem.
