China

Energy production and infrastructure development can have a severe detrimental effect on conifer habitats.  A recent surge in the global demand for metals has led to an increase in mining activities with open-cast mining or strip-mining and its associated activities causing severe environmental damage.  Conifer-rich forests are often affected by this type of mining for example, nickel mining on the Pacific island of New Caledonia. Hydroelectric schemes often cause habitat loss due to forest inundation or indirectly by the loss of downstream habitats through changes in water levels.  Over the past 100 years hydroelectric schemes are responsible for a 15% habitat loss of Lagarostrobos franklinii forest in Tasmania.  Logging activities invariably start with the construction of roads in order to gain access to timber and this can include up to 15% of the consumed logged area. This intrusion is often devastating, opening up the area for further development and as communities grow more infrastructure and services are required.

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 >
