The Reef Corridor of the Southwest Gulf of Mexico: Challenges for its management and conservation

Abstract

Flow of species and spatial continuity of biological processes between geographically separated areas may be achieved using management tools known as Ecological Corridors (EC). In this paper we propose an EC composed of three highly threatened coral reef systems in the Southwest Gulf of Mexico: Sistema Arrecifal Lobos Tuxpan, Sistema Arrecifal Veracruzano and Arrecifes de los Tuxtlas. The proposed EC is supported by the concept of Marine Protected Areas Networks, which highlights the biogeographical and habitat heterogeneity representations as the main criteria to the establishment of this kind of networks. These three reef systems represent the coral biodiversity of the western Gulf of Mexico. Nevertheless there are serious shortcomings in its protection. Under this approach, the challenges that Mexican government will face for management and conservation of this EC are discussed. There is an obvious lack of an adequate legal framework to establish networks of protected areas in Mexico, mainly because national legislation does not consider connectivity as an important factor in the selection of MPA.
