Pampa Grande is located on the edge of the Southern Andean Yungas
The Yungas is a narrow band of forest along the eastern slopes of the Andes mountains from Peru, Bolivia, and down to northern Argentina. The Yungas are an ecoregion that captures the rain and moist mist from the Atlantic Ocean winds. It forms a habitat that lies between two much drier habitats: the Chaco to the east and the Puna (Andean highlands) to the west. The terrain is extremely rugged and varied, contributing to ecological diversity and richness. The southern Andean Yungas (part of northern Argentina) is a subtropical moist broadleaf ecoregion occurring in elevations from 800 to 3000m.
The “mesic” evergreen forest, with trees typically less than 15m tall is dominated by Andean alder (Alnus acuminata) and mountain pine (Podocarpus parlatorei ).
The Yungas ecoregion is home to an astounding biodiversity especially avifauna and is quite strong in endemics, including approximately 10 avian species that are range restricted.
Unfortunately this habitat is under threat, especially in Argentina where the total of the combined four Argentinean parks (1969km2) does not even rival the single Bolivean park in this ecoregion.
