État de la populationExpert
Wild stands of the species are reported to be sparse. This was previously described as a common species in the 1979 Flora of China, which indicates a population reduction since that time. Given the level of human encroachment and development in the distribution area it is most likely the overall population is declining.

Description complète des menacesExpert

The forests in north west Yunnan are threatened by habitat fragmentation, excessive harvesting for fuelwood and timber, increases in tourism and unsustainable practices. These threats are due to the rapid development of social structure in Yunnan during recent decades.

Deforestation is also a big problem in Sichuan, due to industrialization and increasing population forests have been cleared for timber, agriculture and infrastructure. Illegal logging is also a problem in Sichuan.  As this species is found growing in these areas it is likely it may be affected by habitat fragmentation and deforestation.

Mesures de conservation recommandéesExpert

There are no known range-wide in situ conservation actions currently in place or necessary at this time for this species. The species is found in three ex situ collections (BGCI 2016).

Further research is recommended to better determine distribution and population size. This will inform required conservation actions.

In the Chinese Red List (2014) this species is assessed as Vulnerable.
