Chinese Douglas Fir (Pseudotsuga sinensis)

Pair of dimensioned illustrations of the Chinese Douglas Fir seen from the top and elevation views

The Chinese Douglas-fir (Pseudotsuga sinensis) is found in China, Taiwan, and some parts of Vietnam. This is in low to medium elevations with moist temperate or warm temperate conditions. This conifer tree produces wood ideal for construction, building, and making furniture. It is an evergreen tree having a gray or dark gray bark that is thickly scaly and corky and branchlets that are pale yellow or yellowish gray. The crown is broad, domed, or flat-topped. The dark green leaves are straight apex obtuse. Female trees produce cones that are pendulous, ovoid, or oblong and purplish, while male strobili are yellowish. The seeds are light-brown and cuneate ovoid.

Chinese Douglas Firs have a typical overall height between 98’-131’ (30-40 m) and spread diameter of 26’-36’ (8-11 m). Exceptional mature Chinese Douglas Fir trees may grow to heights of 164’ (50 m) in the wild. The trunk of the Chinese Douglas Fir has a diameter of 31”-39” (.8-1 m) with needle-like leaf lengths between .75”-1” (19-25 mm).
