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.

Taiwania cryptomerioides Hayata

Taiwania has an unusual disjunct distribution with the main populations along the border between Yunnan and Myanmar (Gaoligong Mountains) and on Taiwan. There is also a small population in Việt Nam. Historical logging has reduced and fragmented the global population; forest conversion and fires threaten the Vietnamese locality.  Read full species entry >

Taxus calcicola L.M. Gao & Mich. Möller

This species has recently been described from southwest China and northern Vietnam. Since then it has also been recorded from Lao PDR under the name T. wallichiana. While it is not yet included on the IUCN Redlist, it is likely to be assessed as Endangered or Vulnerable under Criterion A and possibly C. Read full species entry >

Taxus chinensis (Pilg.) Rehder

Native to China and Việt Nam where threats include logging and deforestation. Exploitation of its bark and foliage for medical purposes is also a threat. Read full species entry >

Taxus florinii Spjut

This recently described species is restricted to northwest Yunnan and southwest Sichuan. Like other Taxus species in the Himalayas and China it has been heavily exploited. No official IUCN assessment has been undertaken yet but it is likely to meet the criteria for Endangered on the basis of recent and past exploitation. Read full species entry >

Taxus mairei (Lemée & H. Lév.) S.Y.Hu

Scattered throughout southern China, Taiwan and parts of the eastern Himalayas as well as southern Vietnam. Subpopulations are severely fragmented and threatened due to overexploitation for medicinal use, deforestation for agricultural purposes and urbanisation. Read full species entry >

Thuja sutchuenensis Franchet

Represented by a single population in Southwest China where up until 1990 it was thought to be extinct; mainly as a result of  selective logging. Read full species entry >
