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.

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

other links in the chain.we hurt the bond of life that unites us all.
