Visit to Bela Vista biological sanctuary

I visited the biological sanctuary Bela Vista kept by Itaipu Binacional, in Foz do Iguaçu. Has many species of plants and animals which inhabit South America.

About the Bela Vista sanctuary

Was created in 1988 to protect and increase the population of species under threat of extinction in the region. In this sanctuary, you pass through the riparian forest, which stays along rivers and banks with 1400 km² of extension in Brazil and 1500 km² in Paraguay. Inside this sanctuary, the cubs have a survival rate above 70%.


The Itaipu Binacional monitor sediments from the tributaries to the reservoir, collecting samples and making turbidity, filtration, evaporation and granulometry analysis. The sediments cause silting and can reduce the lifespan of hydroelectricity generation.


In the image gallery, the animals under threat of extinction recently posted are found in the Bela Vista sanctuary. In this post, I will show other animals, but aren’t all animals in this sanctuary. This is a white-tailed hawk (Buteo albicaudatus), feeds on insects, mammals, amphibians and smaller birds.
