Location: communities of the Curaray River sub-basin, headwaters (community of San Virgilio, 500-800 m a.s.l.), middle part of the sub-basin (communities of Geyepade and Gomataon, 280-350 m a.s.l.) and lower Curaray (Ninamaru community, 150-200 m a.s.l.).

The Curaray River travels for 800 km in Ecuador and Peru before flowing into the Napo River in Peru. The region has historically been the site of the “rubber fever” and oil extraction, which has left its mark on the populations of the Waorani, Záparos, Gaye, Semigaye, Caniche, Canelos ancestral peoples. The scattered indigenous villages share extensive tropical forests of the Curaray region with countless species of flora and fauna.

The expeditios in the Curaray area generated important data for many groups of animals. NUNA scientists identified 7 species of monkeys: el tamarin (Leontocebus sp.), squirrel monkey (Saimiri cassiquiarensis), White-fronted capuchin (Cebus yuracus), red titi monkey (Plecturocebus discolor), saki monkey (Pithecia sp.), red howler monkey (Alouatta seniculus), common woolly monkey (Lagothrix lagotricha). They also found 34 morfotypes of ants (possibly different species), 26 morfotypes of spiders, 27 species of reptiles, 41 species of amphibians, 116 species of birds, 33 species of bats and over 100 species of fish, some of which are new to science. Considering that this information is preliminary, it is very likely that the numbers of species will increase as NUNA scientists analyze the data collected at the site.
