The Jari channel

Upstream and not far from the mouth of the Tapajós River, a tributary of the Amazon river, is the "Furo do Jari", a channel that allows the entrance of water from the Amazon River into the Tapajós River. The length of the Jari channel is about 17 nautical miles (approximately 19 miles, or 31 kilometers), and it give access to the communities Arapixuna and Carariaca.



The Amazon river has "whitewater", while the Tapajós river is a "clearwater" river, which means, besides its appearances, that they have quite different chemical, physical and organoleptic properties [1]. Being so, the seazonal variation in the mixture of the waters in the surrounding floodplains results in an overall biodiversity enhancement.



I had opportunities to visit the Jari channel and did, up to now (January 2019), 55 observations of 36 different species.
