Habitat and Ecology
Picea aurantiaca is a subalpine species, occurring between 2600 m and 3800 m a.s.l. (-4000 m according to Rehder and Wilson 1914). It is mostly found on calcareous soils. The climate is cold and precipitation varies from high (no figures recorded) in the lower elevations of the SE of its range to only 500-700 mm in the NW. It occurs in mixed coniferous forest, with e.g. Picea likiangensis var. rubescens and locally Abies squamata and Larix potaninii. Betula spp. are the common broad-leaved trees, while Pinus spp. occur mostly after disturbances and at the lower elevations.

Conservation Actions
The Government of China has recently imposed a ban on logging in western China. Increasing the population by protecting seedlings trees from grazing to allow an increase in the population would assist.
