It is located in the southeast of the Federal Capital on the avenue Tristán Achaval Rodríguez, among the streets Viamonte and Brazil . It was created in 1986 by the Municipal Ordinance Nº 41.247 and it possesses a surface of 350 there is.. This administered by Subsecretary of dependent Environment of the Government of the Autonomous City of Buenos Aires).

In the year 1918 in the place where today the reservation is located, the municipal spa was inaugurated that later had to be closed due to the contamination that suffered the waters of the River Plate. In the year 1972 the project arises of creating a city satellite to locate the buildings of the public administration in the city of Buenos Aires . The land was won to the river and it stuffed it to him with demolition material coming from the layout of the freeways.

The filler began in 1978, using a similar system to that of the Dutch polders, but for diverse reasons gave way it in 1981. From that then, you plant and wild animals colonized the area in natural form, transforming the place into a landscape of great beauty. Newly in 1986, the Municipality of the City of Buenos Aires believes, for Municipal Ordinance, the Natural Park and Reservation Ecological Coastal South.

To protect and to preserve the only sector of the city of Buenos Aires with wild atmospheres, with recreational, educational and scientific ends.

Pastizal Pampeano, Lagoons and Taken a bath.

The characteristic atmospheres of the Reservation are the lagunares. It is tight bodies of water, of permanent or temporary character. The scarce depth favors the development of microscopic, marshy, submerged and floating plants, conforming to a series of ambient diferenciables according to the dominant vegetation.

It is common to find in these atmospheres numerous aquatic birds, as the Swan of Black Neck, Gallaretas, Ducks Gulls, etc.; mammals like the Coipo (not well called Otter) and reptiles as the Turtle of Water. Here the fauna finds refuge for the construction of its nests or burrows.

The pastizal is formed by called giant grasses Cortaderas or Line of Fox, due to the brilliant and feathery feather where they are the seeds. Here it is very common to observe Verdones and Picks of Silver, where they feed, they rest and they reproduce. Among the grass undergrowths they inhabit Mice of Field that go desapercibidos for all by their color, fewer it stops their predators: sparrow hawks and snakes.

The forests of the Reservation present a homogeneous composition, as the Forest of I Plane , very common in the Argentinean northeast, and the Forest of Sallow that from the river Chubut until the north of the country is present in all the courses of water. It is very frequent to find marauding in these atmospheres, Thrushes, Tacuaritas and some Owl of the Steeples.

The vegetable communities of the Reservation, in their majority are represented by the aquatic atmospheres. In the banks of the lagoons they settle Juncales-Totorales and other ingrained plants. The floating vegetation is composed mainly of Ferns of water, Lentil of water and Cabbage of water, is also a small variety of submerged plants.

In the pastizal the gramineous drops intermingled with cortaderales prevail and it possesses an arcillo-sandy floor. There plants like the toad Flower and the Bell prosper, among others. The embankment, with a varied flora, possesses prevalence of exotic species as the Castor oil and the Paradise . Among the autochthonous ones we find the Ceibo and the one it Encircle-encircles.

The arbustal of Chilca is developed in sandy floors, forming a cover pure dense, many times, lacking the herbaceous stratum practically. The forests of the reservation are compound for Alisos and Sallows. He Planes, of quick growth and greenish bark gray color, rarely it overcomes the 8 meters high and twenty diameter meters. It is combined with several vegetable species as the Grass of those Taken a bath that it forms most of the floor of the forest when drying off.

This atmosphere will become supposedly, in Marginal Forest , just as it existed skirting the River Plate formerly. The forest of Sallow, tree of cracked bark and wide glass that from the river Chubut until the north of the country is present in all the courses of water, it can be presented in two different ways: as dense forest, where all the copies are of the same age and they form a homogeneous population; or I eat park, where it is presented inserted with big pastizales. In the forests we can differentiate 5 strata: muscinal, herbaceous, arbustivo, arboreal, and epífitico. Comparatively the Sauzal is richer than the Alisal in plants epífitas, as the Carnation of the Air and climbers.

One of the attractive faunísticos of this Reservation composes it the birds, represented for more than 200 species, although not all are present in the same time of the year. The most characteristic birds in this natural area, are the aquatic ones as the Macá, the Biguá, species divers, the Jacana, the Gallaretas, the Garza Lives and Garza Blanca, and among the Ducks the Sirirí Pampas and the majestic Swan of Black Neck.

In the pastizal it is very common the Pick of Silver, characteristic for a stain around the eye, of yellow color. It is also frequent to observe the Verdón, always posed in the feathers of the Cortaderas; its strong and conical pick of color orange, allows him to leave the seeds of those that feeds. The forest on the other hand, it is visited by Thrushes.

It is very common to see them in the floor looking for worms. Real carpenters that look for insects under the bark of the trees with their strong and sharp picks and they catch them with their long and sticky language, they inhabit this atmosphere. Between the trees and bushes is the Blue Tacuarita that, agile and restless, moves quickly among the vegetation, with the line always lifted.

Although the Reservation is known by the quantity and variety of birds that inhabit it, other inhabitants they exist, less visible. The amphibians are represented by the Creole frog that lives in lagoons and temporary puddles, the Frog of the Bramble that has the capacity to change the color of their body according to the sustrato where is, varying from the brilliant green until the brown one and the Toad Digger that inhabits the temporary swamps and flooded fields, and when doesn't reproduce it remains in caves that it digs with their later paws.

Representing the reptiles has the Lizard Overo, also called "Iguana", typical inhabitant of the Reservation. It can be seen it crossing the paths quickly or simply sunbathing during the hours of heat. Their diet is varied, feeds of insects, eggs, mollusks, fish, rodents, amphibians and fruits.

In the lagoons it is frequent to see the Colored Turtle on stones or trunks, rushing to the water when perceiving some sound. In the cortaderal it is to the watching the Yarará or Viper of the cross that feeds mainly of birds and rodents. It is also common to see in this same one ambient to the Green Snake, which is usually volute on the Cortaderas as if was a leaf more. Although relatively scarce due to the scarce surface of the area and the urbanization pressure and recreation that support, the species of existent mammals are difficult to observe due to their small size and to their night habits. Among the most prominent we find the Coipo or "Otter", rodent very associated to the atmospheres of fresh water. feeds mainly of the vegetation that grows beside the curepos of water, the one that also uses to build floating nests in those that rests. Another very frequent rodent is the Cuis Pampeano that is displaced by the Rat Norway, an exotic species. The Bats, only mammals able to fly, are accustomed to it turns at night and they feed mainly of insects. Another mammal difficult to observe but existent in the reservation, it is the Colored Weasel, the female of this marsupial it possesses the you suckle inside a cutaneous pleat or bag, where it takes their breedings in period of nursing.

Two circuits exist, one is the one that begins with the constructions of the Administration of the Reservation, call on the way to the Lizards.

This travels the most important lagoons in the Reservation: that of the coipos, that of the ducks and that of the gulls.

The on the way to the Means leaves of half of the previous one and it drives to the River Plate, passing between the lagoon of the ducks and that of the gulls, and for the alisos forest and the lagoon of the macaes, to these last ones the access is only carried out with an authorized guide.

From the river they leave three roads, that of the alisos, that of the sallows that skirt the respective forests, and the one on the way to the plumerillos, surrounded of cortaderales.
