The world’s newest great ape, revealed a month ago, is already nearly extinct: IUCN

first_imgThis week, the world’s newest great ape Tapanuli orangutan was officially categorized as “Critically Endangered” by the IUCN as the species lost over 80 percent of its global population over generations due to habitat loss.The classification of the orangutan came in conjunction with the conservation union releasing its latest Red List of “Threatened” Species which added thousands of animal and plant species.The list is a mixed bag of good and bad news for conservation. The Tapanuli orangutan (Pongo tapanuliensis) of Sumatra is both the world’s newest known great ape species and its most threatened, after being officially categorized this week as “Critically Endangered,” or nearly extinct in the wild.Researchers last month declared it the world’s eighth great ape species, distinguishing it from the Sumatran orangutan (Pongo abelii) and the Bornean orangutan (Pongo pygmaeus), both of which are also deemed Critically Endangered by the International Union for Conservation of Nature. The report concluded there were about 800 Tapanuli orangutans left in the wild, making it the rarest great ape on Earth.“Due to high levels of habitat conversion and fragmentation, and illegal killing, Pongo tapanuliensis is estimated to have experienced a significant population reduction in recent decades,” the IUCN said, noting that the species had lost 83 percent of its population over the course of three generations.The Tapanuli orangutan (Pongo tapanuliensis) lives in pockets within the Batang Toru forest in North Sumatra province.

The biggest threat comes from the development of a 510-megawatt hydroelectric plant in an area with the highest known density of Tapanuli orangutans. The researchers who described the orangutan suggested that the project could harm 8 percent of the ape’s habitat if completed.“To ensure the long-term survival of Pongo tapanuliensis, conservation measures need to be implemented swiftly,” the IUCN said.The Indonesian Ministry of Environment and Forestry has acknowledged the issues and vowed an assessment of the potential impact from the power plant project on the orangutan habitat. A top official said the ministry would also be more judicious about approving future development projects in the region.The classification of the Tapanuli orangutan, its first by the IUCN, was issued Tuesday as part of an update of the IUCN’s Red List, which saw an additional 1,514 animal and plant species join the “Threatened” categories of “Vulnerable,” “Endangered” or “Critically Endangered.”The update, published in Tokyo, assessed the status of 91,523 species, and found 866 to be extinct.These include three reptile species found only on Australia’s Christmas Island: the Christmas Island whiptail skink (Emoia nativitatas), the blue-tailed skink (Cryptoblepharus egeriae) and the Lister’s gecko (Lepidodactylus listeri).An Irrawaddy dolphin in Cambodia.

In this case, the extent and severity of decline was revealed too late to save these Christmas Island reptiles.”Australia’s increasingly dry and hot climate has also led to a decline in the population of the western ringtail possum (Pseudocheirus occidentalis) by more than 80 percent over the past 10 years, pushing it two categories up from Vulnerable to Critically Endangered.In Japan, a third of 46 endemic reptiles are under threat of extinction, primarily due to habitat loss, predators and collection for the pet trade.The status of the Irrawaddy dolphin (Orcaella brevirostris) and finless porpoise (Neophocaena asiaeorientalis) have also worsened, both moving from Vulnerable to Endangered after a significant decline in their numbers due to fisheries bycatch and habitat loss.“The Irrawaddy dolphin is revered by many communities and dolphin tourism is an important feature of local economies in parts of India and Cambodia,” says Randall Reeves, chair of the IUCN SSC Cetacean Specialist Group. “While the protected status of both species means that deliberate hunting or capture is rare or non-existent, protection from entanglement and other threats is either lacking entirely or largely ineffective. Without practical solutions to this problem, the declines of dolphins and porpoises are bound to continue for the foreseeable future.”The IUCN also reported that 26 six species of wild wheat, 25 species of wild rice and 44 species of wild yam — hardy variants of some of the most important food crops grown today — have been pushed to the brink of extinction by intensive farming, deforestation and urban sprawl.“Wild crop species, for example, maintain genetic diversity of agricultural crops that can adapt to a changing climate and ensure food and nutritional security,” said IUCN director general Inger Andersen.The update wasn’t all doom and gloom, though. There was good news for the kiwi in New Zealand, where conservation efforts have led to a steady increase in the population of both the Okarito kiwi (Apteryx rowi) and the northern brown kiwi (Apteryx mantelli). Both have seen their status improve from Endangered to Vulnerable.“Fortunately, the kiwi downlistings show that there is hope,” said Ian Burfield, global science coordinator at BirdLife International.The northern brown kiwi.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredlast_img read more
