China

Direct exploitation occurs through general logging (deforestation), selective logging or the use of forest non-timber products (FNTP’s). General logging is the biggest threat to conifer species whereby forest habitats are often replaced by plantations, settlements or agricultural land. Selective logging involves the removal of individual tree species for their valuable timber, for charcoal production or fire wood. This practise is often considered to be a sustainable alternative to clear-cutting however, for every tree removed 30 more will become severely damaged because the practise of selective logging is inherently destructive. Conifers play an important role in the production of non-timber products, one example is the use of the foliage and bark of Taxus species for the production of the anti-cancer drug taxol. Although over-exploitation can lead to local extinction, the sustainable commercial and domestic use have the potential of increased incentives for forest conservation.

Calocedrus macrolepis Kurz

A widespread species that has been exploited for timber and resin. Difficulties in estimating the extent of its decline and a lack of information about its staus is some parts of its range have resulted in an assessment of Near Threatened. Read full species entry >

Calocedrus rupestris Aver.,T.H.Nguyên & P.K.Lôc

Calocedrus rupestris was first described in 2008 from Việt Nam: prior to this Calocedrus trees occurring on limestone karst  were wrongly identified as Calocedrus macrolepis.  In 2011 C. rupestris was discovered in Guangxi. Threats include selective logging for timber, deforestation and forest degradation. Read full species entry >

Cephalotaxus fortunei var. alpina H.L.Li

A poorly known variety from the mountains in SW China. Deforestation is likely to have had an impact within its restricted range and therefore it has been assessed as Near Threatened. Read full species entry >

Cephalotaxus hainanensis H.L.Li

Restricted to the island of Hainan, China where the main threat has been exploitation of the bark and leaves for the valuable medicinal extracts. Habitat conversion and deforestation are now the most current threats Read full species entry >
