【night result chart】In pics: guardians of endangered trees in SW China's Chongqing
Thuja sutchuenensis night result chartseedlings are seen at the Thuja sutchuenensis research base of Xuebaoshan national nature reserve in Kaizhou District of southwest China's Chongqing, Aug. 7, 2024. Wild Thuja sutchuenensis is an endangered species of gymnosperm endemic to China and under national first-class protection. In 1998, the International Union for Conservation of Nature declared Thuja sutchuenensis extinct, but the species was rediscovered in Chengkou County in 1999. At present, the number of wild adult Thuja sutchuenensis plants in the world is less than 10,000, and they are only distributed in the areas of Daba Mountains including Kaizhou District and Chengkou County of Chongqing.
In order to protect this endangered species, Yang Quan from Chongqing Xuebaoshan national nature reserve led a team to carry out the investigation and study of wild Thuja sutchuenensis communities, hoping to expand its population.
Through years of efforts, the research team chose to take cuttings as a method to realize the large-scale propagation of wild Thuja sutchuenensis. Up to now, a total of 2.7 million plants have been artificially bred. Since March last year, the artificially bred plants have been transplanted to 18 experimental bases in 11 provinces and autonomous regions including Yunnan, Ningxia, Shaanxi, Gansu and Xizang for ex-situ conservation and adaptive cultivation.
"We hope to take Thuja sutchuenensis as a typical case and to expand our experience to the rescue and protection of more endangered plants," Yang Quan said. (Xinhua/Huang Wei)
