Reserva de biosfera de Yungas, Biosphere reserve in northwestern Argentina.
The Yungas Biosphere Reserve is a large protected area in northwestern Argentina that stretches across two provinces and combines forests, grasslands, and farming areas. The region is drained by the Bermejo River and contains several national parks as well as provincial parks with distinct ecosystems.
The area received official recognition as a biosphere reserve by UNESCO in 2002 to protect its natural resources. This designation marked an important commitment to preserving these complex ecosystems for future generations.
Indigenous communities live throughout the reserve and have shaped how these forests and mountains are used and valued over centuries. Visitors can see settlements and agricultural patches woven into the landscape, reflecting deep knowledge of these ecosystems.
The reserve is accessible through various trails and paths that cross different protected areas with varying difficulty levels. Visitors should prepare for changing weather conditions since elevation and climate can shift quickly across the landscape.
Despite its size, the reserve contains around half of all plant and animal species found in Argentina within a relatively small portion of the country. This exceptional diversity makes it one of the most valuable natural areas in the nation.
