Description

The islands lie in a string along Africa's continental shelf. The five Segundas islands are in the north, separated by a stretch of open water and reefs from the five islands of the Primeiras chain to the south. The eastern sides of the islands are fringed with coral reefs, composed mainly of soft corals, with hard corals at their southern edges. Beds of seagrass are situated between the islands and the mainland, which are important habitats for sea turtles and

s, dugongs and green sea turtles, and creating a better quality of life for the people of the region. The initial goal of the projects was the creation of a 17,000 km2 area to be protected as a marine reserve. This was realized in 2012 when Mozambique established Africa's largest protected marine zone surrounding the islands. Although the joint project has ceased their activities, there is a continuing goal is to increase awareness among local people of how their activities affect the larger environment and their own long-term security and prosperity through the efforts of Fire Island Conservation and other NPOs. Moving towards more sustainable farming and fishing methods is also a focus of educational outreach to area communities.
