Appendix:

“Kunming Base” of Yunnan Introduction and Propagation Centre for Rare & Endangered Plant Species is the only ex situ conservation-based institution founded in Karst areas (mainly for Magnoliaceae) in south China in 1991. The area is 5 ha. With years of experience of introduction, cultivation, propagation and research, we have conserved more than 120 threatened plant species in the centre. Nearly 70 Magnoliaceae, especially those recently found in Yunnan, have been collected and conserved here.


The Daweishan Nature Reserve in Pingbian Miao Autonomous County is a public institution under the leadership of the Forestry Department of Yunnan. Daweishan Nature Reserve is located in the southeast frontier of Yunnan and near to the border of Vietnam and China, close to the original sites of our target species, i.e. Dipteronia dyeriana, Magnolia odoratissima, and Magnolia aromatica. It is 15 kilometres far from Pingbian County site. Daweishan Nature Reserve was opened to public as a provincial scenic and historic interesting area in 1993. It was authorized as a national nature reserve by the State Council in June 2001. It is 30 kilometres long from north to south, and 6 kilometres wide from east to west. The total area is over 43993 hm2. The highest peak is 2365 metres; the second highest point is 2354 metres high, while the lowest altitude is 225 metres. It belongs to the tropical-subtropical ecological type with an annual temperature of 16.5 ℃ and the climate here is described as “flowers bloom in winter, spring stays forever”. There are various types of forestry ecosystems and abundant plants and animals in the reserve. Over 480 nationally protected plant species and over 160 nationally protected animal species live in the reserve and it is reputed as a natural “gene bank of plants and animals”, “the crown of plant kingdom” and a “biological museum”. The reserve is an important place for biodiversity conservation and ecotourism.
