Beni Biological Station Biosphere Reserve, Biosphere reserve in Beni Department, Bolivia.

The Beni Biological Station Biosphere Reserve spans approximately 135,000 hectares with low-lying landscapes that change seasonally. The terrain includes wetlands, open grasslands, and forests that flood at certain times of year.

The reserve was created on 5 October 1982 by Supreme Decree No. 19191 to protect the flora, fauna and water resources of the region. In 1987 UNESCO's Man and the Biosphere programme added it to the World Network of Biosphere Reserves. From 1990 about 30% of the area, some 35,000 hectares, was recognised as Tsimane indigenous territory, and in 2020 it received AICOM certification for bat conservation.

Since 1990, about 30% of the reserve, some 35,000 hectares, has been recognised as Tsimane indigenous territory. This double status as protected area and indigenous land has forced a reformulation of how management policies approach the resident population. Visitors may notice the Tsimane presence in the use of these lands.

The easiest way to reach the reserve is by boat along the Maniqui and Curiraba rivers. During the rainy season, road access becomes unreliable, so planning your visit well ahead is wise.

Of the 138 bat species recorded in Bolivia, 43 have been found in the reserve, which in 2020 received AICOM certification from the Latin American and Caribbean Bat Conservation Network (RELCOM), making it the seventh area in Bolivia with this recognition.
