 In Anjajavy, the mangrove swamps protect the natural Reserve of dry deciduous forest as well as the Marine Reserve.This biotope simultaneously serves as a curtain of protection against strong and salty winds, a fire-wall, a damp buffer useful to the forest during the dry season and as filter against the turbidity of the coastal waters.The two rivers of mangroves on both sides of the Anjajavy forest constitute excellent natural borders for the Protected Area as well as practical transportation routes which allow for better exploration.
