Botanical Description

Nageia wallichiana is an evergreen tree with a conical crown of horizontal branches; it usually grows up to 10 metres tall, but specimens up to 54 metres have been recorded. In larger specimens the straight, cylindrical bole can be free of branches for up to 30 metres and up to 60cm in diameter, though it is often much less[ 329 Title The Gymnosperm Database Publication Author Website http://www.conifers.org/index.htm Publisher Year 0 ISBN Description A vast amount of information on conifers and families of gymnosperms. , 443 Title Biotik, Laos Publication Author Website http://biotik.org/species_list_laos.html Publisher Year 0 ISBN Description Information on more than 100 species of Laotian trees. ].

Logging and forest clearing must have had, and still do have, a negative impact on the total population size of mature trees, but it is virtually impossible to quantify this over such a large and diverse area. Despite the significant loss of habitat across all lowland tropical forests within Nageia wallichiana's extensive range, it is still relatively common and widespread. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ].
