Yasuni National Park is in Ecuador with an area of 9,820 km between the Napo and Curaray rivers in Napo and Pastaza provinces in Amazonian Ecuador. The park is about 250 km from Quito and was designated a UNESCO Biosphere Reserve in 1989. It is within the claimed ancestral territory of the Huaorani indigenous people.
Yasuni is home to several uncontested indigenous tribes, including the Tagaeri and the Taromenane.
The national park lies within the Napo moist forests ecoregion and is primarily rain forest.
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 km) 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.
The park holds a world record 150 amphibian species for places with comparable landscapes. It also is in the top for amphibian diversity compared to other sites sampled in the western Amazon. The total of its amphibian species are more than the United States and Canada combined. Reptile species in the park is also very high with 121 documented species found. In spite of covering less than 0.15% of the Amazon Basin, Yasuni is home to approximately one-third of amphibian and reptile species. The park also harbors high levels of fish diversity with 382 known species. This number is greater than the amount of fish species found in the whole Mississippi River Basin. Yasuni also is home to at least 596 bird species which comprises one-third of the total native bird species for the Amazon. The park is also very rich with many species of bats. On a regional scale, the Amazon Basin has an estimated 117 bat species but on a local scale, Yasuni is estimated to have comparable richness. In a single
