The Hainan gibbons are a critically endangered and important flagship species. Because of this, they serve as an indicator of the health and stability of the tropical island's entire ecosystem, according to Qi. "If the number of Hainan gibbons increases, it indicates that the local environment is healthy, complete and functioning well," Qi says.

Hainan gibbons also play a key role in forest maintenance and reforestation. With long arms and legs but no tail, they typically spend all their time in the trees and rarely set foot on the ground. They usually leap from tree to tree, making them an ideal vehicle for dispersal of seeds for primeval rainforest flora, as well as for the fruit they consume via their excrement. "That is to say, the population of Hainan gibbons is essential for the fecundity of native plant species," Qi says.

To educate people on the island's exclusive residents, exhibitions have been held in schools and communities across the province. From Oct 24 to 31, a science exhibition, Into the Mysterious "Gibbon Universe" of the Bawangling National Nature Reserve — the Familiar and Unfamiliar Facts of Hainan Gibbons was held at Hainan Library. With interesting, vivid and informative pictures and illustrations, the exhibition presented the living habits and population changes of Hainan gibbons, as well as the effects of conservation on the animal and its habitat.

The activity aims to raise awareness among the public, especially youngsters, and encourage them to learn more about the gibbons and forest conservation efforts.

Lei Leyan, a visitor in her 40s, attended the exhibition, and learned a lot of interesting facts about the creatures, such as their family roles and favorite foods, and the significance of protecting the species. "Hainan gibbons are a symbol of the province," she says. "Protecting them is crucial for a sustainable future. And Hainan is making contributions to the biodiversity of China and the world."

With that goal in mind, Qi says that he hopes more young people will join in the conservation efforts, for example, by becoming part of the monitoring team, like Zheng and Ni.

"Hopefully, with more education and publicity, the national park administration will recruit more talent, and young people with a relatively high educational background will join the monitoring team," Qi adds.
