The Mar del Plata Port Reserve is a wetland of approximately 32 hectares, located at the southern end of the port of Mar del Plata. Despite its small size, the area has the greatest biodiversity of the entire General Pueyrredón district. The wetland is home to various species of birds, fish, amphibians, reptiles and mammals. The best represented group is that of birds, with more than 172 species recorded. Among the most characteristic, we can mention the black-necked swan and the coscoroba swan and one of the most colorful and rare, the federal. In the reserve it is also possible to observe endangered species according to IUCN criteria, such as the black-necked gull and the dwarf sparrowhawk. The conservation of numerous species of migratory birds and native waterfowl depends on the subsistence of the lagoons in the area, since scientific studies have determined the real importance of this coastal sector for sustaining the coastal system of migratory birds.
The reserve is surrounded by urbanized, industrial and tourist-recreational areas associated with the Punta Mogotes complex. It is a meeting point between areas of intense human activities and a natural environment with a diversity of fauna and flora typical of wetlands. Its immediacy with the city of the high value for the development of educational and interpretive activities, being a place of easy access for groups of formal and non-formal education. Every year the reserve is visited not only by delegations from schools in Mar del Plata and the area, but also from the Federal Capital and the interior of the country who ask to learn about the port wetland ecosystem.

The conservation of this natural landscape depends on the proper administration and governance of the MPA. This implies an integrated and coordinated work between the authorities responsible for administering conservation (OPDS and Prefectura Naval Argentina since the area is located within its jurisdiction by ordinance 12/1998), tourism, science, education, and private actors with interests in the area.
