The Tapajós-Arapiuns Extractive Reserve (Portuguese: Reserva Extrativista Tapajós-Arapiuns is an extractive reserve in the state of Pará, Brazil.
The Tapajós-Arapiuns Extractive Reserve is divided between the municipalities of Santarém (68.05%) and Aveiro (31.95%) in the state of Pará. It has an area of 647,611 hectares (1,600,280 acres). The reserve lies along the left (west) shore of the Tapajós river in the stretch where it expands to a width of about 8 kilometres (5.0 mi) before joining the Amazon River at Santarém. The Arapiuns River runs through the reserve before joining the Tapajós.
The southwest corner of the reserve meets the Amazônia National Park. The reserve adjoins the Maró Indigenous Territory to the west. The Tapajós National Forest is on the opposite side of the Tapajós River, to the east. The proposed South Amazon Ecological Corridor would link the Tapajós-Arapiuns Extractive Reserve to other protected areas and indigenous territories in the region.
Elevations in the reserve are from 2 to 216 metres (6 ft 7 in to 708 ft 8 in). In the eastern portion along the Tapajós and the northwest altitudes range from 2 to 51 metres (6 ft 7 in to 167 ft 4 in). Temperatures average 25 °C (77 °F). There is high rainfall averaging 2,400 millimetres (94 in) annually, with no marked dry season. Soils are generally infertile. Dense rainforest covers 88% of the reserve, or 591,420 hectares (1,461,400 acres). The vegetation consists of large trees, woody lianas and abundant epiphytes. The Amazonian manatee (Trichechus inunguis) is a protected species in the reserve.
As of 2005 the reserve may have already been suffering from the effects of the Tapajós-Teles Pires waterway, which was causing massive deforestation on the borders of the reserve along the Tapajós and Arapiuns rivers. By 2012 about 51,361 hectares (126,920 acres) of the vegetation had been modified by people, particularly along the banks of rivers and streams. This has caused some siltation and eutrophication of the water bodies.
