Yungas Andinas Regional Corridor Since fragmentation is one of the main reasons for the biodiversity and sustainability loss, it is a matter of intuition to think that reconnection of habitats must be an important step in order to solve this problem. This is the basic idea for connecting reserves by corridors or portions of habitat in condition to link isolated islets of forest. Corridors have been identified as important tools in the design of protected areas, allowing the turn over and recolonization between habitats of proper quality. Using this concept we are following the objective of establishing a Regional Corridor in the Andean Yungas. Sectors of the Regional Corridor: 1. Amboró - Tariquía (Santa Cruz - Chuquisaca - Tarija) 2. Tariquía - Baritú (Tarija - Salta) 3. Baritú - Calilegua (Salta - Jujuy) 4. Calilegua - El Rey (Jujuy - Salta) 5. Austral (Salta - Tucumán - Catamarca)
