Amazon region of Brazil and Peru.Located in the north of South America,from east to west.Also the Pantanal region in the southwestern part of Brazil
From Wikipedia:
The Pantanal is the world’s largest wetland area, a flat landscape, with gently sloping and meandering rivers that flood during the wet season, submerging over 80 percent of the area, and nurturing the world's richest collection of acquatic plants.
It is situated in South America, and is thought to be the world’s most flora and fauna dense ecosystem. It is often overshadowed by the Amazon Rainforest, partly because of its proximity, but is a just as vital and interesting part of the Biosphere. The Pantanal is mostly found within Mato Grosso and Mato Grosso do Sul, which are states of Brazil. There are also small portions which are within Bolivia, and a small amount in Paraguay. In total, the Pantanal covers over two hundred thousand square kilometers.
This ecosystem is home to a known 3500 species of plants, as well as OVER 650 BIRDS, and 400 species of fish. The Pantanal is a natural home for the Hyacinth Macaw. This bird is endangered due to its US$]10,000 price tag on the black market. Other threatened species include the Jaguar, Maned Wolf, Giant Otter, Giant Armadillo, and Brazilian Tapir.
The Pantanal has an average yearly rainfall of 1000-1400 mm, but is fed by the Upper Paraguay River. Its average temperature is 25 degrees Celsius, but temperatures can conceivably fluctuate from zero to forty degrees Celsius.
During the rainy season (December to May), the Pantanal water levels will rise more than three meters. Just as annual floods on the Nile allow for fertile, farmable land, the dramatic increase of water during the rainy season nourishes the producers of the Pantanal, which in turn nourishes all the other species as well. Humans have taken advantage of this so much that it has become a problem. Approximately 99% of the land in the Pantanal is privately owned for the purpose of agriculture.
The Pantanal is a natural water treatment facility. It supplies freshwater to the nearby areas by removing chemicals and other pollutants from the water which flows through it. However, when this “cleaning system” becomes overloaded, species which call the Pantanal home begin to suffer. Industrial development (especially gold mining) has begun to cause such problems already.
