Cupressaceae

Here human intrusions includes recreational activities and civil unrest. Although recreational activities can have very positive effects on biodiversity by providing much-needed income for protected areas, they can have a negative impact if not managed effectively. For example, intensive recreational facilities such as campgrounds often result in the removal of the local vegetation a fuel wood for camp fires. Because conifers are a common component in mountainous regions where they often dominate, they are particularly vulnerable to the development of winter sport activities such as ski resorts.  Over 90% of the major armed conflicts between 1950 and 2000 occurred within countries containing biodiversity hotspots, and more than 80% took place directly within hotspot areas. Civil unrest can have a serious negative impact on biodiversity.  The Việt Nam war used poisonous Agent Orange as an aerial forest defoliant in which 14% of the forest cover was affected.

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 >
