Picea brachytyla var. complanata (Mast.) W.C.Cheng ex Rehder
Widley distributed in the Sino-Himalayan region where logging has greatly reduced the population and caused fragmentation
China: W Sichuan, NW Yunnan, SE Xizang [Tibet]; N Myanmar [Burma]; Possibly also in India: east Arunachal Pradesh.
Habitat and Ecology
In coniferous forests at elevations between (1600) 2000 and 3600 (3800) m on mountain slopes and in high river basins.
The fragmented range and effects of past logging (more than 30% population reduction in past 100 years) render this variety Vulnerable. The fact that the decline may not be reversible justifies use of criterion A2 rather than A1 of the China Plant Specialist Group assessment (Wang and Xie 2004).
Logging and deforestation have substantially reduced the extent of coniferous forests in the region and have had an impact especially on this variety with its more restricted range.
The ban on logging will reduce the rate of loss of trees but is unlikely to cause the loss to cease altogether. Establishment of a conservation programme desirable.
