| Abstract |
In the tropical-subtropical transition, on the northern coast of the state of São Paulo (Brazil), the presence of a port and an oil terminal, associated with other human activities such as fisheries, tourism, and industrialization, pressure the ecological integrity and biodiversity of the Alcatrazes archipelago, which comprises two marine protected areas (ESEC Tupinambás and REVIS Alcatrazes). This work aims to elaborate an Environmental Sensitivity Index (ESI) map to subsidize the protection of these conservation units. ESI map used primary data from demersal ichthyofauna and secondary data for other biological, socioeconomic and oceanographic variables. The operational map produced (scale 1:50000) highlights strategic points of biological importance and for the activities developed in Alcatrazes. The sheltered regions of the archipelago, composed of exposed cliffs with lower declivity, or rocks sheltered from wave action, showed highest rates of environmental sensitivity. The Alcatrazes’ biodiversity presents 835 taxa, and many are considered threatened according to different protection levels, endemism and commercially important species. Marine protected areas are not necessarily safe from oil spills that occur beyond its geographic limits, making the Alcatrazes archipelago map an essential tool for actions to fight oil spills and for drawing up contingency plans, as well as a data source for future work. |
