What is the Cataratas del Iguazo

The Park Nacional Iguazú, created in 1934 by Law 12,103, owns around 67,620 hectares that were declared Natural Patrimony of the Humanity in 1984 due to their scenic beauties and to the great biological diversity of the subtropical forest.

This located natural sanctuary in end NE of the Argentine Republic, to benign rains and temperatures (15º C of average in winter and 30º C of average in summer) conforms a loaded humidity atmosphere, almost without wind due to the leafy vegetal cupola.

The Iguazú river has a total route of 1320 km until its opening in Parana, 23 km after the cataracts.
Framed by low coasts it most of has in his route a variable width that goes from the 500 to the 1,000 metres. Within the National Park, one is high and mighty to about 1,500 metres and it twists towards the south, soon to retake towards the north, forming an ample one Or, that contains in its opening, the steep unevenness in the land that gives rise to the cataracts: imposing waterfalls.

In their great curve, a proliferation of stumbling blocks, small barren islands and extended islands fragment the river in numerous arms. When arriving at the precipice, each of them gives rise to a jump, whose set constitutes the great fan that is the Cataracts of the Iguazú.

The Park lodges a Natural Patrimony that it includes:

• A native flora with more than 2000 species: leafy ferns, bromelias, orquídeas, palms and gigantic trees that serve as support a great variety of trepadoras enredaderas, that provide permanently with fruits that they attract monkeys, coatíes, deer, toucans, to only name some.

• 450 species of birds, those that are exhibited without timidity in the first hours in the morning and to the dusk, being able to be observed with facility toucans, magpies, teros, parrots and the incredible billhooks, this last species exclusive of the area of the Cataracts of the Iguazú.

• 80 species of mammals, among them to five varieties of felines cross merged the selváticos claroscuros.

• And countless insects, between which a great amount of colorful butterflies stands out.

• The innumerable water obstacles of the area, are guarded by jacares and herons, that nourish themselves of smaller fish.

The importance of conservation of the area resides in which in her species are protected that are in danger of extinction like being: yaguareté (Panther onca), ocelote (Felis pardalis), yacutinga (Aburria jacuntinga), macuco (Tinamus solitarius) to mention some of them, who still find in the Park Nacional Iguazú the conditions for their survival.
