Yasuni National Park, Ecuador

Yasuni National Park is arguably the most biologically diverse spot on Earth. The park is at the center of a small zone where amphibian, bird, mammal, and vascular plant diversity all reach their maximum levels within the Western Hemisphere. Moreover, the park breaks world records for local-scale (less than 100 km2) tree, amphibian, and bat species richness, and is one of the richest spots in the world for birds and mammals at local scales as well.[1]

Yasuni is home to several uncontacted indigenous tribes, including the Tagaeri and the Taromenane.
