Flooded Forest of the Rio Tabajós Pará, Brasil

Every year, over 250,000 km2 of Amazon floodplain forests are covered by water that overflows from rivers. This annual phenomenon forms the most extensive system of riverine flooded forests on Earth - a drastic revolution in the landscape that is vital for the efficient functioning of the Amazon River Basin.
Floodplain forests represent between 3-4% of the Amazon Basin area and are highly productive riverside areas that are flooded during the rainy season, and which receive rich sediment from the Andes Mountains. These factors have resulted in the evolution of ecosystems and habitats with a high number of species. (Source: WWF International)
