Amazon Delta

The Amazon Delta (Portuguese: delta do Amazonas) is a vast river delta formed by the Amazon River and the Tocantins River (through the Pará River distributary channel) in northern South America. It is located in the Brazilian states of Amapá and Pará and encompasses the Marajó Archipelago, with Marajó Island as its largest island. The region is 160,000 km2 and has 49 towns, with most of these being small towns with less than 20,000 inhabitants. The main cities located in the vicinity are Belém and Macapá, each with its respective metropolitan area. It is the largest river delta in the world. It releases one fifth of the total amount of freshwater that is discharged into the earths oceans, into the Atlantic Ocean, with some estimating that equates to 200,000 litres a second. The area has wetlands, streams, lagoons and rich ecosystems and biodiversity. It is a vital area for wildlife, with extensive mangroves in wetland forests, that cover an area of 38,304 km2 of the delta, with 75% of Brazil's mangroves located in the Amazon Delta.
