A recent report, published by the Government of Indonesia with support from the Food and Agricultural Organization and Norway's International Climate and Forest Initiative, states that orangutan populations (Pongo spp.) have increased by more than 10% in Indonesia from 2015 to 2017, exceeding the government target of an annual 2% population increase [1]. This assessment is in strong contrast with recent publications that showed that the Bornean orangutan (P. pygmaeus) lost more than 100,000 individuals in the past 16 years [2] and declined by at least 25% over the past 10 years [3]. Furthermore, recent work has also demonstrated that both Sumatran orangutans (P. abelii) and the recently described Tapanuli orangutan (P. tapanuliensis) lost more than 60% of their key habitats between 1985 and 2007, and ongoing land use changes are expected to result in an 11-27% decline in their populations by 2020 [4,5]. Most scientific data indicate that the survival of these species continues to be seriously threatened by deforestation and killing [4,6,7] and thus all three are Critically Endangered under the International Union for Conservation of Nature's Red List.
最近，印度尼西亚政府在粮农组织和挪威国际气候与森林倡议的支持下发布了一份报告，称 2015 年至 2017 年间，印度尼西亚的猩猩（Pongo spp.）数量增加了 10%以上，超过了政府规定的每年增加 2%的目标[1]。这一评估与最近的一些出版物形成了鲜明对比，后者表明，过去 16 年来，婆罗洲猩猩（P. pygmaeus）的数量减少了超过 10 万头[2]，过去 10 年至少减少了 25%[3]。此外，最近的研究还表明，苏门答腊猩猩（P. abelii）和最近描述的塔潘里猩猩（P. tapanuliensis）在 1985 年至 2007 年间失去了超过 60%的关键栖息地，而目前的土地利用变化预计将导致它们的数量在 2020 年减少 11%至 27%[4,5]。大多数科学数据表明，这些物种的生存仍然受到森林砍伐和捕杀的严重威胁[4,6,7]，因此，根据国际自然保护联盟的红色名录，这三个物种均被列为极危物种。
