A worker called Rahman found the ᴄʀʏing ape hidden in bushes near the West Borneo farm and reported the discovery to his manager.
Rahman and his co-workers decided not to intervene, thinking the baby’s mother would return to retrieve him.
But ᴛʀᴀɢɪᴄᴀʟly when they returned the next day the youngster was all alone in the same spot.
A team from International Animal Rᴇsᴄᴜᴇ (IAR) and members of the Natural Resources Conservation Centre (BKSDA) then travelled to the plantation in Tanjung Pasar Village, Ketapang District.
Workers were waiting to hand over the little ape, who they had named Rahman after the man who found him.
Karmele Llano Sanchez of IAR Indonesia said: “For an animal like an orangutan, witnessing the ᴅᴇᴀᴛʜ of its mother is a profoundly sʜᴏᴄᴋing experience.
“That is undoubtedly why Didik looks so sᴀᴅ and ᴅᴇᴘʀᴇssᴇᴅ. It will take a long time for him to recover from the ᴛᴇʀʀɪʙʟᴇ ᴛʀᴀᴜᴍᴀ he has been thʀᴏᴜɢʜ and start to take an interest in his surroundings.”
Didik was strong enough for sᴜʀɢᴇʀʏ after several weeks of ᴛʀᴇᴀᴛᴍᴇɴᴛ and nutrition and had the ʙᴜʟʟᴇᴛ removed from his shoulder.
Vᴇᴛ Ayu Budi Handayani said: “The sᴜʀɢᴇʀʏ went without a hitch.
“Fortunately the ʙᴜʟʟᴇᴛ was lodged cʟᴏsᴇ to the surface of the skin so it was a straightforward procedure to remove it.
“No one could call Didik lucky after all he’s been thʀᴏᴜɢʜ but certainly he was fortunate to sᴜffᴇʀ only a fairly superficial ᴡᴏᴜɴᴅ after most likely being S.H.O.T by the same ɢᴜɴ that ᴋɪʟʟed his mother.”
“Didik looks very handsome now,” Ayu added. “We are still trᴇᴀᴛing the skin where the ʙᴜʟʟᴇᴛ entered his body but it is healing beautifully.”
Although still in ǫᴜᴀʀᴀɴᴛɪɴᴇ, little Didik has already started learning to climb with a lot of encouragement from ᴠᴇᴛ Uwi and some strategically placed food trᴇᴀᴛs.
IAR chief executive Alan Knight said: “Sᴀᴅʟʏ it is not uncommon for our team to trᴇᴀᴛ orangutans that have been S.H.O.T.
“The adults have usually survived an attempt to sʜᴏᴏᴛ them ᴅᴇᴀᴅ, while babies like Didik have been ᴡᴏᴜɴᴅed by ʙᴜʟʟᴇᴛs intended to ᴋɪʟʟ their mothers.
“These ɪɴjᴜʀies at human hands ᴄᴀᴜsᴇ the animals to sᴜffᴇʀ until the day they are ʀᴇsᴄᴜᴇd and ᴠᴇᴛerinary teams like ours step in to repair the ᴅᴀᴍᴀɢᴇ.”
Borneo, the third biggest island in the world, has seen forests cut ᴅᴏᴡɴ at an alarming rate in recent years, removing orangutans’ haʙɪᴛat.
A report earlier this year from the Current Biology Journal has blamed forest ʟᴏss on miners, loggers and palm oil producers.
Palm oil is used in household products from chocolate bars to medicines and make up, and requires the mass-clearing of land for production.
Among other ᴄᴀᴜsᴇs, the oil production has led to 18,000 square miles of forest to be cut ᴅᴏᴡɴ in Borneo since 1985 – an area the size of Belgium, the WWF has said.
