(550 ha), (1991). It consists of Playa Grande, which is one
of the most important nesting sites in the world for the letherback turtles. On
every year from X to III arrive other species of turtles (olive ridley, pacific
and hawksbill) to lay their eggs.
It`s covered by 400 ha mangrove swamps (there are six
species of mangroves). Identification has been made of 57 birds (roseate
spoonbills). There are also common raccoons, caymans, white-nosed coatis and
howler monkeys. In recent years local villagers have been employed as government rangers to guide visitors to nesting sites.
