The population of Hainan gibbons, known as the world's rarest primates1, has slowly grown to 29 thanks to afforestation efforts in China's southern island province of Hainan, conservationists have said.
 
海南黑冠长臂猿,世界上最珍稀的灵长类,数量已缓慢增长至29只,这要归功于海南岛的植树造林行动。
 
 
The apes, endemic to the primeval rainforests in the Bawangling National Nature Reserve, have only four families but are expected to add a new family, said Lu Yongquan, deputy chief of the management of Bawangling.
 
"We found a lone2 female monkey during this year's investigation3, which means we're likely to see the creation of a new family," Lu said, explaining that a Hainan gibbon family usually has one male and two female adults and will drive out new adult monkeys to form new families.
 
Numbering over 2,000 in the 1950s, Hainan gibbons' population plunged4 to about seven in the 1980s, with excessive hunting and lumbering5 pushing them to the brink6 of survival.
 
To save them from extinction7, the local government established the Bawangling reserve in the monkey's last habitat in the 1980s, and afforestation drives were launched to increase the forest coverage8 from about 80 percent to 98 percent.
 
"About 100,000 trees have been planted in the past two decades, which helped restore the fragmented forest system," said Chen Qing, a researcher with the reserve who has monitored the threatened species for decades.
 
Typically living in rainforest trees over 10 meters tall, the Hainan gibbons, with long arms and legs but no tail, rarely set foot on the ground, making captive breeding difficult.
