The "yungas" are forest lands that spread along the Andes from northern Argentina to Venezuela, and from an altitude of 500 to 3,000 metres, according to their latitude. From the floristic point of view they belong to the Amazonian Domaine and their typical formation is the so called misty forest. These montain forests maintain high levels of endemism and biodiversity, but they are being threatened by increasing deforestation, especially for crop production.
