Chen Zhengping, a forest ranger in a city-level nature reserve in Danzhou City, inspects mangroves in the reserve in south China's Hainan Province, Dec. 9, 2019. Hainan, rich in mangrove resources, now has about 5,727 hectares of mangrove forests, most of which are distributed in a variety of protected areas - nature reserves and wetland parks. Chen Zhengping, Feng Erhui, Luo Lixiang and Lyu Shiyang are all grassroots mangrove protecting and managing personnel in different mangrove reserves in Hainan Province, taking on responsibilities including patrolling, monitoring and knowledge popularizing. Through years of practicing, they gradually transformed themselves from normal mangrove protectors to experts who truly know about the situation of ecological environment and the status of the animals and plants in their patrol areas.
