Description:

Trees to 30 m tall; trunk to 1 m d.b.h.; bark purplish brown, nearly smooth or irregularly fissured. Facial leaves on young plants bluish green adaxially, narrowly oblanceolate, 4-7 × 1-1.2(-2) mm, with an elevated midvein; lateral leaves almost as long as or slightly longer than facial leaves, usually

straight, 5-10 × 2-3 mm, on adult plants small, 2-7 mm, ridged and with a white, depressed stomatal band abaxially. Pollen cones yellowish green, subglobose, 4-5 mm. Seed cones brown when ripe, subglobose, 1.5-2.5 × 1.2-2.2 cm. Seeds 4-5 mm, 3- or 4-ridged; larger wing ovate-dolabriform, ca. 5 mm, smaller wing ca. 1.5 mm or a mere strip. Pollination Mar-Apr, seed maturity Oct-Nov.

Habitat and Ecology:

Habitat and Ecology

This conifer is usually a minor constituent (can be dominant in some forests) of subtropical to warm temperate evergreen (mixed) mesophytic forest. In China, when this forest is in an undisturbed state, it is dominated by numerous angiosperm trees e.g. Castanopsis spp., Quercus spp., Lithocarpus spp., Nyssa sinensis, Pasania spp., Schima argentea, S. superba, and a few other conifers e.g. Cephalotaxus fortunei and Nothotsuga longibracteata. With continued disturbance conifers like Cunninghamia lanceolata and especially Pinus massoniana or P. densata become more abundant and eventually dominate. The altitudinal range of Fokienia hodginsii is from 350 m to 2,300 m a.s.l. Soils are acidic (pH 5-6) yellow or brown loamy sands over sandstone, shales, granite, or rhyolite and well drained. Mean annual precipitation is 1,200 mm or more. In Viet Nam and Lao PDR it may be associated with conifers such as Pinus krempfii, Taiwania cryptomerioides (Viet Nam) or Cunninghamia konishii (Lao PDR and Viet Nam).

Justification

Although there is a shortage of quantitative data on population reductions, given the levels of targeted exploitation of this highly sought after timber species, it is very likely that the population reduction has exceeded 30% in the past three generations (more than 300 years) and may be approaching 50%. The area of occupancy is also within the threshold for Vulnerable under criterion B2, and there is severe fragmentation of the popualtion. Declines are continuing in large parts of its range despite enforcement measures now in place in China and Viet Nam. Based on available information an assessment of Vulnerable under the criteria for A2 and B2 is probably conservative: with better information, particularly for natural population sizes in China, this species could be upgraded to Endangered.
