The Southern Andean Yungas is a tropical and subtropical moist broadleaf forest ecoregion in the Yungas of southwestern Bolivia and northwestern Argentina.[1]

Setting[edit]

The ecoregion occurs in elevations ranging from 800 to 3,000 metres (2,600 to 9,800 ft).[1]

Climate[edit]

This ecoregion has a subtropical highland climate. The climate is influenced by trade winds that bring about 2,500 millimetres (98 in) of rain per year.[1]

Flora[edit]

The Southern Andean Yungas consists of a mesic evergreen forest, with trees typically less than 15 metres (49 ft) tall. Between 1,200 to 2,500 metres (3,900 to 8,200 ft) the forest is dominated by Andean alder (Alnus acuminata) and mountain pine (Podocarpus parlatorei). At lower elevations these species mix with other trees, especially Lauraceae and Myrtaceae.[1]

Fauna[edit]

Many tropical species find the southern limit of their range in this ecoregion.[1]

Mammals that may be found here include the white-lipped peccary (Tayassu pecari), the collared peccary (Pecari tajacu), and the South American tapir (Tapirus terrestris). Cats include the jaguar (Panthera onca), puma (Puma concolor), margay (Felis wiedii), and jaguarundi (Puma yagouaroundi).[1]

Birds with ranges restricted to this ecoregion include the red-faced guan (Penelope dabbenei), Rothschild's swift (Cypseloides rothschildi), and the rufous-throated dipper (Cinclus schulzi).[1]
