Acer erythranthum is endemic to Viet Nam. The species is globally assessed as Near Threatened as it has experienced a population decline of almost 30% so nearly qualifies as Vulnerable A2c. The species lacks regeneration potential and is used as a timber. It is recommended that further information is gathered on this species habitat, population size and threats to ensure the species threat status is being correctly assessed.

Population [top]

Population:The population size of this species is not known but population is in decline. Population has declined by almost 30% over the last three generations (Gibbs et al. 2009).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in evergreen forests, often on deep fertile soils (Chinh et al. 1996).

Use and Trade [top]

Use and Trade: This species is used as a timber for construction and making household items (Gibbs et al. 2009).

Threats [top]

Major Threat(s): The species lacks good natural regeneration even though it is a good fruiting crop (Chinh et al. 1996). The species is also potentially threatened by its use as a timber.

Conservation Actions [top]

Conservation Actions: The species is reported from eight ex situ collections with this name (BGCI 2017) however it is likely that these have been misidentified. It is not known if this species is found in protected areas. Further information on this species habitat, population, geographic range and threats needs to be collected. Research into improving the regeneration of this species should also be undertaken.
