China

The China Threatened Conifer Region includes most of mainland China. Climatically and topographically it is diverse and one of the world's major centres for plant diversity. It has a rich conifer flora with more than 150 taxa including iconic endemic conifers such as Metasequoia glyptostroboides, Pseudolarix amabilis and Cathaya argyrophylla. Unfortunately almost half have been assessed as threatened. The principal threats arise from conversion of forest for agricultural use, plantation forestry and urbanization as well as recent exploitation for timber. A number of taxa are relictual and naturally have small populations: these are especially susceptible to anthropogenic influences. Several taxa, including, Cupressus funebris, Cunninghamia lanceolata and Platycladus orientalis have a long history of cultivation and their natural distributions have become unclear and it is uncertain if any wild populations still remain. The majority of threatened species are concentrated in the Sino-Himalayan areas of Yunnan and Sichuan, the limestone karst areas of Guangxi and Guizhou and the mountainous areas of Fujian and Zhejiang.

Pinus wangii

This species is only known for certain from karst limestone areas of three counties in Yunnan where it has been heavily exploited for its timber, despite the ruggedness of the terrain. Lower altitude sites are also indirectly impacted by the clearance of the valleys and lower slopes for agriculture. Read full species entry >

Pseudotaxus chienii (W.C. Cheng) W.C. Cheng

Although it has a widespread distribution in eastern China this species is very rare and has declined due to deforestation. It has also been exploited to some extent for Taxol production. Read full species entry >
