Mbaracayu Forest Reserve
A privately held Atlantic Forest reserve in Canindeyu, a UNESCO biosphere reserve with a girls' school inside it.
Updated 18 October 2026
Mbaracayú protects around sixty-four thousand hectares of Atlantic Forest in Canindeyú, bought in 1991 through an international debt-for-nature arrangement and held by the Moises Bertoni Foundation under a legal protection that runs in perpetuity; UNESCO designated the wider area a biosphere reserve in 2000. The forest holds jaguar, tapir, giant anteater and a bird list of over four hundred species, and Aché communities hold traditional hunting rights within it. A residential agricultural school for girls from rural families operates inside the reserve. Trails, a canopy tower and river sections are used by visitors, with lodging at the field station, and everything must be booked in advance.
History
The reserve was created by an agreement between the government of Paraguay, the Moisés Bertoni Foundation, UNESCO and The Nature Conservancy, ratified in 1991 by national law 112/91, which set it aside in perpetuity to protect the forest, its wildlife and its cultural heritage while promoting sustainable development. The Moisés Bertoni Foundation still runs it, and on 19 December 2003 it was put forward to UNESCO as a proposed World Heritage Site (Wikipedia, Mbaracayú Forest Nature Reserve).
