This region has suffered changes for the man's action. The animals were scarce. The most common were the deer, the skunk, the nandu, the hairy one, Ia mule, the fox pampeano, the vizcacha, the puma and the cat of the pajonales. Among the birds the butchers highlighted, as the chimango and the carancho, besides the tero, the chajá and the parrot.
Besides the fauna mentioned for the plain, beside the rivers, especially on the Paraná it existed a great variety of reptiles there, as the terrible snake yarará, next to lizards, batrachians and many birds. Among these last ones they were the partridges, the chorlo, the owl, the owl, the hummingbird, the oven-bird, the benteveo and the starling.
When arriving the first Europeans to the plain pampeana, by the middle of the XVI century, the big changes began. They brought horses and bovine that they became wild and they began to populate the plain. The food abundance and the absence of big butchers favored their express development, competing with autochthonous species as the deer and the nandu.
The hunt to obtain leather and suet, the civil wars of the first part of the XIX century and the malones of the natives made that the wild livestock began to disappear. It was replaced by other bovine and horsy races, more appropriate to the new agricultural and cattle activities, starting from 1870 when it began to arrive the alluvium inmigratorio.
The cultivations and the cattle raising didn't only decimate the wild livestock, but also to deer, ñandúes and almost the whole terrestrial fauna. Of the same way, most of the flora and fauna beside the river Paraná extinguished due to the installation of port infrastructure and of services. What stays until today is part of the avifauna that inhabits the new mounts, planted as screen of winds to protect the livestock and the cultivations. |
