Every October 24th is International Gibbon Day. Among them, the Hainan Gibbon is the most endangered primate in the world. At one time, there were only 13 gibbons and only 16 in the Bawangling National Nature Reserve of Hainan Island. It is unique in the existing forest of square kilometers.
Since 2003, Kadoorie Farm and Botanical Garden has been working with Hainan Bawangling National Nature Reserve to carry out the conservation of Hainan Gibbon.
In recent years, they have built a canopy corridor for the Hainan Gibbon, and recorded this experience in detail, organized it into an academic article, and published it in the latest issue of Nature’s Scientific Reports.
Hainan Gibbon is a species endemic to Hainan Island. Adult males are black all over, and females are golden yellow. Their family group consists of one male, two females and children. They live on trees throughout their lives and never go to the ground. They have been listed in the IUCN Red List in the early years. (IUCN Red List) is listed as a critically endangered animal.
In 2003, Kadoorie Farm and Botanical Garden was invited by the Hainan Provincial Forestry Bureau to start the local conservation of Hainan gibbons.
After years of hard work, the number of Hainan gibbons has returned from 2 groups of 13 at the time to 5 groups of 33 at present.
In 2015, the team built a canopy corridor for the Hainan Gibbon for the first time to reconnect a daily passage that was destroyed by a landslide caused by the super typhoon "Ramason" in 2014.
Through the canopy corridor, the team hopes to reduce the impact of landslides on the Hainan Gibbon's range of activities and the risk of falling to the ground when forced through.
According to the monitoring of the infrared camera installed by the team, although the canopy corridor was first used by Hainan Gibbon only 176 days after its establishment, its use frequency is getting higher and higher. Three years later, it is quite close to the typhoon destroying the original natural passage by the Gibbon. Level.
Kadoorie Farm and Botanic Garden also pointed out that although conservation methods to improve the fragmentation of wild animal habitats through the establishment of artificial canopy corridors are becoming popular around the world, the establishment of canopy corridors for gibbons is not only the first case in China, but also rarely in foreign countries. The literature discusses its design and effectiveness.
Therefore, this experience has been recorded in detail and organized into an academic article, and published in the latest issue of Scientific Reports, a sub-Journal of Nature.
