Description: Iguaçu National Park is a national park in Paraná State, Brazil. It comprises a total area of 185,262.5ha and a length of about 420km, 300km of which are natural borders by bodies of water and the Brazilian and Argentinean sides together comprise around 260,000ha. Iguaçu National Park was created by federal decree nr. 1035 of January 10, 1939, and became a UNESCO World Heritage Site in 1986. The park is managed by Chico Mendes Institute for Biodiversity Conservation (ICMBio).The park shares with Iguazú National Park in Argentina one of the world’s largest and most impressive waterfalls, extending over some 2,700m. It is home to many rare and endangered species of flora and fauna, among them the giant otter and the giant anteater. The clouds of spray produced by the waterfall are conducive to the growth of lush vegetation.HistoryThe Iguaçu National Park owes its name to the fact it includes an important area of the Iguazu River (Portuguese: Rio Iguaçu). Approximately 50km2 of the length of the river makes up the Iguaçu Falls.It is the most important park of the Prata Basin and, since it is a haven to a significant genetic asset of animal and vegetal species, it was the first park in Brazil to receive a Management Plan. As foreseen by Rebouças, the park's basic goal is the preservation of the highly relevant ecologically and scenic natural ecosystems, thus enabling scientific research and the development of environmental education and interpretation activities, recreation in natural surroundings and the ecological tourism.
