鉴于该物种已极度濒危且威胁加剧，保护组织提升其等级的可能性较高，但需考虑官方决策周期。
依据IUCN红色名录或国际保护组织官方公告，若在截止日前更新保护等级则判定为是。

Add as preferred source Male Tapanuli orangutan. Credit: Andrew Walmsley for SOS Deep in the forests of North Sumatra, Indonesia, lives the Tapanuli orangutan (Pongo tapanuliensis), the world's rarest great ape. Fewer than 800 individuals remain, confined to the Batang Toru ecosystem, a landscape that is also home to other rare species like Sumatran tigers, Sunda pangolins, agile gibbons and helmeted hornbills.
For years, debates about the future of Batang Toru have largely focused on major development projects, particularly hydropower, gold mining and geothermal energy. But our new research, published in Biological Conservation, suggests that the story is more complicated.
We tracked forest loss and the human activities driving it by combining three approaches. First, we used satellite data to see where forest had been lost and what was driving that loss. Second, we spoke with local communities to validate our spatial observations and determine the drivers from a local perspective. Finally, we used an impact evaluation approach called the synthetic control method. This technique created an artificial twin of the forest to show what would have happened if extractive industries had never arrived in Batang Toru.
By combining these three methods, we examined the locations of forest loss, the social and economic processes driving it, and its additional impacts on the ecosystem. The results reveal that there is no single threat to the Tapanuli orangutan. Instead, multiple pressures are acting simultaneously—ranging from extractive industries and logging to agricultural expansion and, increasingly, climate-related disasters.
Between 2000 and 2023, Batang Toru lost 7,659 hectares of forest (18,900 acres), equivalent to about 5% of its total forest cover. Forest loss accelerated sharply after 2012, around the time three major extractive projects were initiated in the region.
我没那么确定，现在市场波动太大了。

新闻里第 3 点才是关键，市场好像还没充分定价。
