A cover from Brazil which includes a stamp celebrating the Iguazu (Iguaçu) Falls (the 2,00 rs stamp on the left). The Iguazu Naional Park is inscribed as an UNESCO World Heritage Site since 1986. Together with Iguazú National Park on the Argentinian side, the park protects Iguazu Falls, one of the world's largest waterfalls, and is home to many rare and endangered species such as giant anteater or the giant otter. The site had been listed as endangered 1999–2001 due to an illegally opened road through the park, dams on the Iguazu River and helicopter flights.
