The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Critically Endangered
Assessment status abreviation
CR
Assessment rationale/justification
This species is very rare but found only in the degrading mixed evergreen forests. Though the Extent of Occurrence and Area of Occupancy of this species are much larger than the threshold level, the habitat quality and quantity have decreased at least more than 80%. Moreover, the total mature individuals in the wild will not exceed 250. Therefore, the species qualifies as Critically Endangered.
