A great biodiversity of fauna in Machu Picchu. Establishment of Machu Picchu Sanctuary as a protected area, specifically as a Historic Sanctuary, has had positive benefits since its inauguration in 1981. Despite some serious environmental conflicts, the Sanctuary o Machu Picchu has helped wildlife in some sectors. Sightings of animals like the spectacled bear (Tremarctos ornatus) and neotropical river otter (Lontra longicaudis) along the highway (at km markers 107 and 112, respectively) are proof of this great biodiversity. http://ping.fm/WKHKW
