Residential and commercial development

Fires may be the result of natural phenomena such as lightning or they may be man-induced. Usually natural fires are an integral part of plant community development and influence such things as soil nutrient availability and biological diversity. In contrast, uncontrolled or wildfires disrupt such processes and can have a catastrophic impacts. The vast majority of wildfires are intentionally set and often occur in conifer forests. In recent years extended droughts, together with the rapidly expanding exploitation of tropical forests and the demand for the conversion of forests to other land uses, have resulted in a dramatic increase in wildfires. While some conifers have evolved to be fire dependent by having serotinous cones that open and release their seed in response to fire, their populations are so small or fragmented that even natural fires may be catastrophic. This is particularly evident in areas with a Mediterranean climate. It is the introduction of inappropriate fire regimes (frequency, severity, or seasonal timing) that can have the most severe impact.

Abies delavayi subsp. fansipanensis (Q.P.Xiang) Rushforth

This subspecies, described in 1997, is restricted to a single mountain in Northern Việt Nam. The main threats are its small population size and restricted distribution which make it potentially susceptible to stochastic events.  Read full species entry >

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 >

Foliage

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 >
