Justification:
The truly wild and natural (not introduced and feral) stands of this taxon are very scattered. Large trees only remain in a few remote places, and often these are "protected" as Buddhist holy trees. The timber is much valued, and protection outside of traditional culture is minimal.

History:

1998	–	Data Deficient (Oldfield et al. 1998)
1998	–	Data Deficient
1997	–	Rare (Walter and Gillett 1998)

Geographic Range [top]

Range Description:	The native range of the species has only recently been better resolved. The truly wild natural stands are very scattered and confined to deep river gorges of the Yangtse, Yalong (?), Lankong (Mekong) and Nu (Salween) Rivers, SW China. The stands in NW Yunnan appear to be mostly pure. It was thought previously that these stands may have been planted.
Countries:	Native: China (Sichuan, Tibet [or Xizang], Yunnan)

Conservation Actions [top]

Conservation Actions:	Traditional Buddhist culture protects certain trees. Very few protected areas seem to contain the species. The species is widely cultivated in the region in certain areas, e.g., around Kunming, Yunnan, from where it has subsequently invaded e.g., the Western Hills. These occurrences were formerly held to be natural and some local botanists still argue that this is the case, which may be the reason why this species does not appear the Red Data Book of Chinese Plants.
