M2 Deployed Here!

Location Summary

M2 covers two multiple use areas under the jurisdiction of the Ministry of Environment: the 192.2 square-km Caletas-Arío National Wildlife Refuge (created in 2006) and 820 square-km Cabo Blanco Marine Management Area (created in 2016). The presence of an array of threatened species (olive ridley sea turtles, green sea turtles, hawksbill turtles, bull sharks, hammerhead sharks, manta rays) that use the diverse habitats in the area (mangrove swamps, sandy beaches, rocky outcrops) for breeding, feeding or aggregating, as well as the existence of an overlapping small scale snapper fishery justified the creation of both multiple use marine protected areas. Both sites harbor sea turtle nesting beaches, and the mouth of the Bongo River (in the Caletas-Arío Wildlife Refuge) has already been identified as a breeding ground for bull sharks and critically endangered hammerhead sharks, as well as habitat widely used by spotted rose snapper, the main target of small scale fishers.
