An uncommon silence within the forests of north Sumatra in Indonesia is worrying wildlife consultants and conservationists.

Right here, within the mountainous forests of Batang Toru, is the place that they had at all times seen and heard the world's rarest ape, the Tapanuli orangutans.

However ever since Cyclone Senyar devastated Sumatra on 25 November, the critically endangered primates haven't been seen within the space, conservation staff say.

Their absence has fuelled hypothesis as as to if the nice apes had been swept away by floods and landslides. And whereas some imagine the animals might have travelled to a safer location, a carcass discovered within the space, stated to be that of an orangutan, is fuelling conservationists' fears.

Fewer than 800 Tapanuli orangutans stay and any loss would have a severe impression on the species, conservationists say.

Humanitarian staff advised the BBC they discovered the lifeless animal semi-buried within the particles of mud and logs in Pulo Pakkat village in central Tapanuli district earlier this week.

"Once I first noticed it I used to be unsure what it was, as a result of it was sort of defaced, maybe as a result of it was buried beneath by the sludge and logs," stated Deckey Chandra, who has been working with a humanitarian staff within the space. He beforehand labored within the conservation of the Tapanuli orangutans.

"I've seen a number of lifeless our bodies of people up to now few days however this was the primary lifeless wildlife," he stated. "They used to come back to this place to eat fruits. However now it appears to have turn out to be their graveyard."

Mr Chandra shared with the BBC photos he took of the carcass, a few of which present him with the lifeless animal.

Conservationists working within the area imagine it's of the Tapanuli orangutan, a species that was solely found in 2017. The opposite two species are Bornean and Sumatran orangutans.

Greater than 900 folks have died on account of heavy rain, floods and landslides since Cyclone Senyar ravaged elements of Indonesia in late November. Lots of are nonetheless lacking, with many villages in Sumatra utterly destroyed because the storm swept throughout the island.

Professor Erik Meijaard, managing director of Borneo Futures in Brunei, is now finding out the disasters' impression on the orangutans with the assistance of satellite tv for pc photographs.

He stated 4,800 hectares (11,860 acres) of forest on the mountain slopes may be seen as destroyed by landslides - however since a part of the satellite tv for pc picture is cloud lined, he is extrapolated the destruction determine to 7,200 hectares in his preliminary remark.

"The destroyed areas would have contained some 35 orangutans, and contemplating the violence of the destruction it would not shock us if they're all lifeless. That is a significant blow to the inhabitants," he advised the BBC.

"These areas present as naked soil on satellite tv for pc imagery the place two weeks in the past it was main forest. Full destruction. Many patches of a number of hectares utterly denuded. It will need to have been hellish within the forest on the time."

Prof Mejjard stated he too has seen the image of the lifeless orangutan shared by Chandra.

"What struck me is that every one the flesh had been ripped off the face," he stated. "If a couple of hectares of forest comes down in large landslides, even highly effective orangutans are helpless and simply get mangled."

Panut Hadisiswoyo, founding father of Orangutan Data Centre which works for the conservation of the primates within the area, stated the carcass meant it was extremely potential some Tapanuli orangutans had been unable to flee as speeding waters and landslides swept via their habitat.

Photos displaying the carcass of a Sumatran elephant, one other critically endangered species, being swept away by floods in Aceh in northern Sumatra went viral on social media final week.

The island hosts a variety of endangered species like Sumatran tigers, elephants and rhinos.

However conservation staff say there are explicit issues for orangutans and different primates, like gibbons, as a result of big elements of the mountainous forest within the Tapanuli district noticed large landslides because of Cyclone Senyar's excessive rainfall.

Some locals say the primates will need to have escaped earlier than the catastrophe struck, as they'll sense hazard beforehand. However some primate consultants say that won't have been the case.

"Throughout heavy rains orangutans both simply sit in a tree or collect branches and leaves to make use of as an umbrella after which watch for the rain to cease," stated Serge Wich, professor of primate biology at Liverpool John Moores College, who has carried out analysis on Tapanuli orangutans.

"However this time, by the point the rain stopped it was too late: elements of their habitat - the slopes of valleys - had been worn out by landslides, which implies there will need to have been penalties for them."

The current floods have additionally broken numerous orangutan analysis centres in Sumatra - together with at Ketambe, the world's first orangutan analysis centre, in Aceh.

Dr Ian Singleton, scientific director for the Sumatran Orangutan Conservation Programme, stated the Ketambe centre is now nearly utterly destroyed.

"It must be rebuilt as quickly as potential so it will probably proceed to play that function in defending the forests in that space and its orangutans."
