Machu Picchu life zones – Biodiversity and Ecosystems. Machu Picchu Historic Sanctuary has greater biological diversity than neighboring ecosystems. In the Aobamba River watershed (the lower, western part of the Sanctuary of Machu Picchu) are the “jungle brows,” or upper limit of tropical vegetation in this part of the Andes. These “brows” contain great flora and fauna biodiversity, and combined with the mountainous ecosystems found within the Sanctuary, make Machu Picchu a special place full of biodiversity. The Historic Sanctuary of Machu Picchu also has a great number of native species, genetic banks, and ecosystems, and is therefore a conservation priority. http://ping.fm/iNAAP
