Las Yungas Biosphere Reserve: Argentina's Andean Biodiversity Hotspot

Nestled in the northwestern provinces of Salta and Jujuy, Argentina, the Las Yungas Biosphere Reserve is a breathtaking embodiment of the region's rich biodiversity and cultural heritage. This vast protected area, situated within the southernmost part of the eastern mountainous forest of the Andean Range, encompasses a tapestry of landscapes that seamlessly blend the high Andean mountain ecosystems with the lush subtropical lowlands, creating a unique transitional zone between the drier Gran Chaco region and the arid, high-altitude Puna region.

A Mosaic of Ecosystems

From Cloud Forests to Agricultural Lands

The Las Yungas Biosphere Reserve is a true ecological marvel, encompassing diverse habitats and ecosystems. From the misty cloud forests and subtropical low mountain jungles to the montane forests and grasslands, the reserve showcases the incredible biodiversity of the Andean region. Additionally, the reserve includes extensive agricultural land dedicated to cultivating sugar cane, citrus fruits, soybeans, and cotton, reflecting the region's rich farming heritage.

Riparian Corridors and Natural Connections

One of the reserve's most striking features is the network of rivers that intersect the landscape, creating riparian forests on both margins. These natural corridors serve as vital ecological connections, facilitating the movement and migration of various species and contributing to the region's overall biodiversity.
