Ranger shows monkeys humans can be kind

"This is 'Dagezi', whose group has two female monkeys, five juvenile monkeys, and two infant monkeys," he says.

Through the years, the monkeys have lived in nearby forests and mountains and have developed a great rapport with Yu. When they hear his voice, they run towards him.

The monkeys not only understand his whistles and words; they also dare to have fun near him.

Getting the hang of caring for the monkeys, getting along with them, or even befriending the monkeys, is a source of pride for Yu.

He knows the secrets of making friends with monkeys. "We protect nature and get on well with monkeys like we are friends. The longer we get on, the closer we will become," says Yu.

"If we cut down the trees and hunt the wildlife as before, we and our future generations will face the consequences," he says.

In around the 1980s, hunting and logging inflicted enough damage to the habitats of the monkeys to pose a threat to their survival.

"Back then, there were fewer woods and bare mountains that led to food reduction and depletion in the number of monkeys. It was rare to see monkeys and they would run away immediately when they heard people's voices," Yu recalls, believing that the lesson is profound and the loss is substantial.

In 1983, China established the reserve to save the endangered monkeys. Their number has since risen to around 3,000 nationally thanks to the joint efforts of the government, researchers and local villagers, according to Lai Jiandong with the reserve.

The reserve also put in a concerted effort with relevant parties to develop a management approach, focusing on not only protecting the monkeys, but also on bolstering the survival and development of nearby residents.

The reserve employed the local residents as forest rangers. Yu, one of them, earns around 1,800 yuan ($254) a month, and his family of four has a total annual income of 40,000 yuan, which allows his family to afford a decent life.

By the end of 2019, nearly 17,000 villagers in Dechen had been hired as government-paid forest rangers through ecological poverty-relief programs.

Yu is living a happy and rewarding life. In his spare time, he takes care of orchids in his yard located inside the reserve.

"We should protect the environment with dedicated efforts so as to leave lucid waters and lush mountains to our future generations," says Yu.
