Course
[edit]The river rises in the 342,192-hectare (845,570-acre)Nascentes da Serra do Cachimbo Biological Reserve,a strictly protected conservation unit established in 2005 in theSerra do Cachimbo.It is one of the headwaters of theXingu River.[3] It flows for 900 kilometres (560 mi) before joining the Xingu, running through the 3,373,133.89-hectare (8,335,195.4-acre)Terra do Meio Ecological Station. The river varies greatly in volume depending on the season, and in the dry season includes waterfalls, rocks and rapids.[4]
The Iriri River flows through theTapajós–Xingu moist forestsecoregion.[5] The river is rich in fish, including many species found only there and in the Xingu. Large sections remain unexplored due to its remoteness in a region surrounded byAmazon rainforest,and sections with strong current and cataracts.[6]
