CCTV News: Spring is a critical period for the breeding of deer in Hainan slope. To ensure that the deer can eat fresh tender grass, the Datian National Nature Reserve in Dongfang City, Hainan Province conducts planned and controlled fire operations every spring.

Through aerial shots, we can see that a large area in the Daejeon National Nature Reserve is charred black, which is a trace left by the recent fire update of vegetation.

Lin Xianmei, senior veterinarian at Datian National Nature Reserve in Hainan, said: "By fire updates, they can kill ticks and harmful microorganisms, so that the grassland can sprout more tender buds, and ensure the food of Hainan slope deer."

According to reports, wood ash after burning is a natural fertilizer that can improve the soil structure and increase soil fertility. In addition, the renewal of vegetation in fire has a little-known benefit for Hainan slope deer.

Lin Xianmei said: "When we have burned, the deer likes to come out to lick wood ash, because the deer is an alkaline food. The deer licks the deer with wood ash is equivalent to adding some trace elements."

It is understood that the deer in Hainan is the only tropical deer species in my country. It is only distributed on Hainan Island and belongs to the national first-class key protected wildlife. At present, the number of sloping deer populations in the Datian Reserve has recovered from 26 in the 1960s to about 400.
