Just two years after the historic identification in Indonesia of the Tapanuli Orangutan, the first great ape discovered since the Bonobo from the Democratic Republic of the Congo in 1929, the species has officially joined the list of the world’s most imperiled primates, published in the ‘Primates in Peril: The World’s 25 Most Endangered Primates, 2018-2020’ Report.

The main threat to the species is an ongoing hydroelectric dam project, which the IUCN SSC Primate Specialist Group Section on Great Apes has requested to be put on hold, as well as ongoing forest conversion and human-orangutan interactions that have led to orangutans being killed and wounded. With fewer than 800 individuals left in the wild, the species is in need of swift conservation action to prevent its extinction.

“The inclusion of the critically endangered Tapanuli Orangutan on the official list of the world’s most endangered primates is not surprising given the existing threats to its small population, but this underscores a tremendous opportunity,” Dirck Byler, Global Wildlife Conservation’s Great Ape Conservation Director and Vice Chair for the IUCN SSC’s Primate Specialist Group’s Section on Great Apes, said in a statement. “As the home of the Tapanuli Orangutan and two other orangutan species, Indonesia has the chance now to become a leader in great ape conservation by implementing the kinds of measures that will not only protect this special animal and its habitat, but that has the potential to positively impact local economies and livelihoods through ecotourism. That is what this report is really about; ensuring that we are identifying those primate species in most need of help and engaging the lawmakers, conservationists, indigenous people and community members who can help change the course of history for them.”

The biennial ‘Primates in Peril’ report, which is a collaborative effort of the IUCN SSC Primate Specialist Group, the International Primatological Society, Global Wildlife Conservation and the Bristol Zoological Society, outlines the 25 most endangered primates based on the passionate nominations of primate champions from four regions of the world: Africa, Madagascar, Asia and the Neotropics. Primates include not only monkeys and apes, but also lemurs, lorises, galagos, and tarsiers.

Two of the species in the 2018-2020 Report, the Tana River Red Colobus in Kenya and the Niger Delta Red Colobus in Nigeria, are among GWC’s priority species and belong to one of the most threatened group of primates in Africa, the Red Colobus Monkeys.

“The Tana River Red Colobus and the Niger Delta Red Colobus are just two species, but the threats that they face, primarily habitat destruction and poaching, are the same threats that could really land any of the Red Colobus Monkeys onto the list of the world’s most imperiled primates,” said Aghomo Florence, Red Colobus Conservation Coordinator for the IUCN SSC Primate Specialist Group and African Primatological Society. “Our goal is to try to prevent Red Colobus species from showing up on this list in the future by helping the species rebound in the wild.”

In 2018, GWC, the African Primatological Society and the IUCN SSC Primate Specialist Group launched the continent-wide Red Colobus Action Plan to identify priority actions and sites across 20 countries to set up effective wildlife conservation programs; support a new generation of local African conservation leadership around Red Colobus; develop initiatives to link and support site-based action; and establish standardized monitoring tools.

GWC’s specific efforts to recover the Tana River Red Colobus and protect the Niger Delta Red Colobus fall under this initiative. GWC works with local partners on establishing and enhancing community conservancies, implementing community-based protection measures to prevent hunting, and developing monitoring programs with local and indigenous communities for these species.

43% of the world’s primates are classified as critically endangered or endangered by the IUCN Red List of Threatened Species, the primates listed in the ‘Primates in Peril’ Report represent those most in need of conservation action and most likely to benefit from the attention that results from the release of the report. In the case of the Northern Muriqui Monkey and Purple-faced Langur, for example, inclusion in the report historically helped spur and unlock support for conservation action.

“At GWC and the IUCN SSC, we don’t just compile this list and then sit around waiting for these species to vanish before our eyes,” said Russ Mittermeier, Global Wildlife Conservation’s Chief Conservation Officer and chair of the IUCN SSC Primate Specialist Group. “‘Primates in Peril’ is a powerful call to action that has helped raise awareness about the plight of primates generally and those most endangered specifically, helping conservationists prioritize their efforts and develop effective partnerships with governments and local NGOs and communities.”

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 and four of them reinstated after they were previously removed. The list includes seven species from Africa, five from Madagascar, seven from Asia and six from the Neotropics.

“This report reveals the bleak prospects of some of the world’s most incredible animals. Despite this, I still have hope that this is not too late,” said Christoph Schwitzer, Chief Zoological Officer at Bristol Zoological Society and IUCN Red List Authority Coordinator for the SSC Primate Specialist Group. “There is an unprecedented level of interest in world environmental issues, particularly among the younger generation, many of whom are more inspired, passionate and motivated than ever before to do their part to help make a difference. It is this kind of support, combined with effective conservation action, which is vital if we are to avoid losing these wonderful and charismatic animals forever.”

Other species of note in the 2018-2020 report include the Skywalker Hoolock Gibbon from China and Myanmar, which was discovered only in 2017 and is new to the list; the Western Chimpanzee from a number of West African countries, whose population could drop dramatically if the current rate of population decline continues; and the Golden-headed Langur from Vietnam, which numbers a mere 50-60 individuals. The Golden-headed Langur has been included on every ‘Primates in Peril’ list since its inception, but the report has helped spur conservation efforts that have resulted in a reversal of the decline in recent years.
