^aTotal species known for Yasuní National Park as a whole (∼10,000 km²), from data synthesized for this paper, unless noted.

^bLower total represents mammal species known to occur in Yasuní. Higher total is an estimate that includes species known or expected to occur in Yasuní.

^cFish species known for Yasuní [68].

^dFish species expected for Yasuní (K. Swing, unpub. data).

^eVascular species known for Yasuní (H. Mogollon and J. Guevara, unpub. data, G. Villa, unpub. data, [92]–[94]).

^fVascular plant species expected per 10,000 km² in the global plant diversity center within which Yasuní lies [91].

^gTotal threatened species known to occur in Yasuní, including only those species listed as Critically Endangered, Endangered, or Vulnerable in the IUCN Red List of Threatened Species [47]. Data synthesized for this paper, unless noted.

^hLower total represents threatened plant species known to occur in Yasuní. Higher total is an estimate that includes threatened plant species known or expected to occur in Yasuní.

ⁱTotal regional endemics known to occur in Yasuní, from data synthesized for this paper, unless noted. Dashes indicate unknowns. See text for further description of regional endemics.

^jEstimated range of total regional endemic plant species that occur in Yasuní. See text for derivation of estimates.
