Download ‘Primates in Peril: The World’s 25 Most Endangered Primates 2018-2020’

Biological Anthropologist Reiko Matsuda Goodwin contributes to New List of World’s 25 Most Endangered Primates

Bronx, New York, Oct. 9 – The Tapanuli orangutan, the indri, and the white-thighed colobus are listed among the World’s 25 Most Endangered primates. The list includes seven species from Africa, five from Madagascar, seven from Asia and six from the Neotropics. Twelve of the species in the 2018-2020 report were not in the previous report, with eight of those appearing on the list for the first time. 

The biennial Primates in Peril report is a collaborative effort of the IUCN SSC Primate Specialist Group, the International Primatological Society, Global Wildlife Conservation and the Bristol Zoological Society. 

Reiko Matsuda Goodwin, a faculty member at Fordham University, whose areas of expertise include primate behavioral ecology and conservation, contributed significant research about the population size of the white-thighed colobus to the report. The white-thighed colobus is distinguished by the silvery-white thighs and a white ruff around its face.
