The surrounding valleys have been cultivated continuously for well over 1,000 years, providing one of the world's greatest examples of a productive man-land relationship; the people living around Machu Picchu continue a way of life which closely resembles that of their Inca ancestors, being based on potatoes, maize and llamas.
Machu Picchu also provides a secure habitat for several endangered species, notably the spectacled bear, one of the most interesting species in the area. Others animals include: dwarf brocket, the otter, long-tailed weasel, pampas cat and the vulnerable ocelot, boa, the Andean cock of the rock, and the Andean condor." Source: UNESCO/CLT/WHC
