Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This is a species of high elevations in the great mountain ranges of SW China, occurring between 2,400 m and 4,300 m asl, but usually between 3,000 m and 4,000 m, commonly on north-facing slopes. The soil is a grey brown mountain podzol. The climate is extremely wet, with cool summers and cold, snowy winters (annual precipitation ranges from 1,000 mm to 3,000 mm and more). It grows mixed with other conifers, such as Picea likiangensis, P. brachytyla var. brachytyla, or in pure stands towards the tree limit. At lower elevations it is sometimes mixed with Tsuga chinensis, T. dumosa, Juniperus formosana and broad-leaved trees, e.g. Betula albosinensis, Betula platyphylla var. szechuanica, and Quercus semecarpifolia. Abies delavayi, however, is less common with these trees than A. forrestii.
