    Ecological Characteristics

    Given its oceanic island character and the small size of the islands, the terrestrial fauna of the Archipelago is diverse but not very abundant, maintaining a relatively high degree of endemism. Among the terrestrial fauna resources, the presence of species of black crab (Gecarcinus ruricola), shanky (Gecarcinus lateralis) and white crab (Cardisoma guanhumi), which are captured and traded locally, stands out.





    Socio-Economic Characteristics

    Most of the land in the transition zone is destined to densified human settlements that make up the urban structure and corridor, international airport, seaport, coast guard station, road structure, extensive development of tourism activity, commercial and hotel infrastructure. There are also some soils destined to agricultural activities mainly on the northwestern side of the island of San Andrés, where the operating infrastructure of solid waste management, wastewater, energy generation, and fiber optic cable services also operate.
