The creation of the Punta Tombo Marine Protected Area made it possible to conserve a large key marine-coastal sector as a transit and feeding area for the Magellanic penguin, whose largest colony of approximately 200,000 pairs is located in the Punta Tombo Natural Protected Area. This colony shows a marked decrease in the number of breeding pairs and scientific studies provided evidence that one of the main causes would be the decrease of food in the marine areas near the colony during the most critical stage of the reproductive cycle of the species. This led to the creation of the Marine Protected Area, whose integrated management with the Natural Protected Area contributes to the conservation of the coastal breeding area and the marine-coastal transit and feeding environment of the Magellanic penguin. The protected area also benefits a large number of coastal and marine bird species and marine mammals that feed in the area. This Marine Protected Area is located within the ¨Patagonia Azul¨ Biosphere Reserve, approved in 2015 during the 27th Session of the International Coordinating Council of UNESCO’s Man and Biosphere Program (MAB).
