1 . Four wild young pandas were found at different times walking around with their mothers in a nature reserve in northwestern China in recent months, a report said on Sunday. Infrared (红外线的) cameras in Baishuijiang National Nature Reserve in Gansu Province caught four young pandas following their mothers and learning survival skills, such as feeding themselves, in the first quarter of 2019.

It was the latest finding of new young pandas in the area, which has the largest population of wild pandas among China’s 67 nature reserves. The fourth national survey on pandas, released in 2015, said there were 110 wild pandas living in the Baishuijiang area. A total of 1,864 lived in China.

The Baishuijiang National Nature Reserve has used infrared cameras since 2012 to monitor pandas, but this is the first time that four pairs of pandas have been found. “In the past, we found one pair every quarter at most,” said He Liwen, director of the Baishuijiang reserve. The young pandas’ body sizes suggested that two of them were a year and a half old, while the other two were almost 2 years old.

“The four pairs were caught in different places far away from each other. It’s very easy to see the differences,” he said. “So we can be sure of the number. “Baishuijiang staff members also found rare wildlife, including golden monkeys, Asian golden cats and gazelles.

The reserve director attributed (把……归因于……) the good news to the government’s hard work and local people’s efforts to protect the natural habitat over many years. “It’s a process of continuous, growing progress,” he said.
