Indochina

The Indochina Threatened Conifer Region focuses on mainland Southeast Asia and includes Myanmar, Thailand (as far south as the Isthmus of Kra), Lao PDR, Cambodia and Việt Nam. Central physical features of this area include the Annamite Mountains that form the border between Lao PDR and Việt Nam, the Hoang Lien Mountains in northwestern Việt Nam and the extensive karst limestone areas of northern Việt Nam and the adjoining areas of China. Climates are variable depending on altitude and distance from the coast with some areas experiencing subtropical climates with distinct wet and dry seasons while others are more seasonal. Vegetation types range from subtropical evergreen forests to subalpine bogs and meadows. The conifer flora is very diverse with at least 15 genera and 35 species present. Almost one third are endemic and at least 20 are globally threatened. Notable endemic species include Pinus krempfii and Xanthocyparis vietnamensis. Several taxa are represented by small disjunct subpopulations with the main populations found in other Regions, sometimes at considerable distances. Principal threats in this region include conversion of forests for agriculture, forestry and urbanisation, overexploitation for timber, illegal logging and wildfires.

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 >

Cupressus tonkinensis Silba

A critically endangered species restricted to a small area of northern Việt Nam. It is not included on the IUCN Redlist as it is treated as a synonym of Cupresus torulosa on the World Checklist, the IUCN's primary reference source for conifer taxonomy. Research since 2005 indicates that it is a distinct taxon. Read full species entry >

Fokienia hodginsii (Dunn) A.Henry & H.H.Thomas

A very widespread species that has been heavily exploited for its valuable and durable timber. Despite legal protection, illegal logging continues to reduce the number of mature trees throughout most of its range. Read full species entry >

Glyptostrobus pensilis (Staunton ex D.Don) K.Koch

Wild populations are only known to occur in small fragmented stands in Lao PDR and Việt Nam. Once widespread in southeast China, centuries of agricultural expansion have resulted in the loss of probably all natural populations in that area. Current threats include habitat conversion, swamp drainage and illegal logging.  Read full species entry >

Juniperus recurva var coxii (A.B.Jacks.) Melville

A graceful weeping tree from SW China and the adjoining Himalayas. Large trees are now rare as its timber has been highly valued for coffins and furniture. Currently it is assessed as Near Threatened. Read full species entry >

Keteleeria evelyniana Mast.

Although widely distributed in southern China, Lao PDR and Việt Nam, natural populations have undergone a significant decline mainly due to the conversion of its habitat for agriculture and logging.  Read full species entry >

Keteleeria fortunei (A.Murray bis) Carrière

A relatively widespread tree occurring across much of southeastern China at lower altitudes. Deforestation has had sufficient impact to warrant lisiting this species as Near Threatened. Read full species entry >

Nageia fleuryi (Hickel) de Laub.

A small tree usually restricted to karst limestone areas, mostly in Vietnam, Lao PDR and southern China . The timber is selectively logged for use in fine crafts. Read full species entry >
