Taiwan

The Malesiana Threatened Conifer Region spans six countries in Southeast Asia: Brunei Darussalam, Indonesia, Malaysia, Singapore, the Philippines and Papua New Guinea. Habitats for the conifers include forests that are everwet, montane ericaceous, peat swamp and mangrove. The conifers mainly include podocarps, most of which are abundant in mid-to high-elevation forests, however, with an increasing elevation stands become more frequent and often the subalpine forests is dominated by one or few species of conifer. Dacrydium species sometimes occur in lowland heath forests (kerangas), typically on the island of Borneo. The Araucariaceae is represented by Araucaria (two species) and Agathis (ca seven species) which form huge emergent trees in a wide range of altitudes. In north-west Sumatera and northern Philippines drier sites on poor acid soils support pine forests which are fire-adapted. The Malesiana Region currently contains 27 globally threatened conifer taxa and the main threats include logging, deforestation, mining, drainage of peat swamps and expansion for agriculture purposes. Global climate change may be having an effect on a number of endemic montane species; most tropical conifers are fire and drought intolerant.

Cunninghamia konishii Hayata

A fast growing tree that is disjunctly distributed in Taiwan and along part of the border between Lao PDR and Việt Nam.  In the recent past it has been heavily exploited throughout most parts of its range: logging continues in Lao PDR.  Read full species entry >
