GENERAL INFORMATION OF THE AREA
PN Pre-Delta (Pre-Delta National Park) was created in 1992, in order to preserve a sample of the ambient of the “Delta Superior” from the Parana River. It has a 2.458 hectares surface and it is located in the southwest side of Entre Rios, 6 km away from Diamante city.
The Park belongs to Delta and Parana Islands eco-region. This eco-region belongs to flood valleys from the low and media way of Parana and Paraguay rivers, and includes the “Delta del Parana”. Low and flood islands compose the Park's landscape.

NATURAL RESOURCES
Landscapes, flora and fauna
The group of islands that composes this Park shapes the typical landscape f the “Delta”: “albardones” and depressed interiors cover by little lakes.
Dense groups of “camalotes” or “aguapey”, with beautiful shade of violet flowers, and “irupes”, whose circular big flowers are floating, compose the local vegetation.
The islands area has “ceibos” and “curupíes” forests, and others covered by “timbo blanco”. The low zones are covered by dense groups of “paja de techar” and “paja boba”, and also has some watered mirrors.
In the region forests composed by “sauces criollos” and “alisos de rio”, usually have birds like “espinero rojizo”, which constructs its suspension nests over the water, and mammals with aquatic habits like the “carpincho”, whose footprint can be observed in the path.
The fauna, abundant and varied, includes “coipo” or “nutria” and “lobito del rio” populations. Also had been detected the presence of the “yacare ñato”.
The most outstanding species of birds are ducks, “caraus”, “chajaes”, storks, heron and “martin pescadores”, like the big one or “matraca”, which becomes an emblematic species of this protected area, because it is abundant and it is easy to be observed.

CULTURAL RESOURCES
The first inhabitants of the region took advantage of the resources that offers this heterogeneous landscape, composed by a diversity of ambient that includes precipices, “albardones”, little lakes, “bañados”, islands and marshes.
This environmental diversity offers a big variety of resources like small and medium fishes, aquatic mammals, like otters and “carpinchos”, molluscs and also animals from the nearby plane, like stags and “ñandu” eggs.
The inhabitants moved in canoes using harpoons and tips made by bone and wood. Rests of ceramic artefacts decorated with animals –parrots, hawks, otters and owls- signs the close relation between these groups and their environment.
The querandies, aborigines related to the tehuelches from the north of the Patagonia, occupied these territories and continued their predecessors coexisting with the guaranies that came from the north of the Mesopotamia.
Since the spanish people arrival in the XVI century, these populations became disappearing because of war, illnesses and wage-earning job in the cities. Only a few Guaranies communities concentrated in Misiones, where they still live.
This territory later integrated Entre Rios province, developing extensive stockbreeding since the creation of the National Park.
Why Guaranies and Querandies could hunt “venado de las pampas” and “ciervo de los pantanos” and nowadays are in danger of extinction? The economic activities that were developing in the last centuries and the excessive hunt modified the natural environment of these species.
Today, the Reserve keeps the rest of the original ambient, developing conservation polities that tend to achieve a sharp developing, including the community in the task and fortifying the link between the communities and their environment.
