Yungas 2007

The Cafotrop/Energia/Muséum project has three strands corresponding to the three tropical forest field missions in three chosen sites in Gabon, Argentina and Madagascar between 2006 and 2007. The second mission took place in the Yungas in north-west Argentina from 28 May to 16 June 2007 (20 days).

The Yungas refer to the forests which cover the eastern slopes of the Andes up to 2,500 metres above sea level in Argentina, Bolivia, Ecuador and Peru. They are constantly watered by heavy rain or by persistent mists, which give them their distinctive characteristics and make them a unique biome, one of the richest in terms of flora and fauna. The Yungas have been classed as a UNESCO Biosphere Reserve and belong to the 25 biodiversity hotspots defined by Meyers et al. (2000).

During this mission, four sites were studied, each with different altitudes and plant profiles. All the explored sites are situated in the provinces of Salta and Jujuy, on a north-south axis at the level of the Tropic of Capricorn (between 23° 05’ and 24° 30’ south latitude): The Calilegua nature park, the Finca Urundel (between Libertador and Oran), a site near Los Naranjos along the San Andres river north of Oran and a site north of Salta near the km 1640 on National Route 9.
