The population is estimated to number more than 8 million individuals, but very few large mature individuals.
Habitat and Ecology
This variety occurs in coniferous, mixed and broad-leaved forests as an under-storey shrub or a small to medium sized tree, in mountains from 2000 to 3200 metres above sea-level. The species probably coppices from the base when cut.
Human Uses
This variety is used for its timber and for firewood. This variety yields high quality wood used in building houses, bridges (durability of the wood) and furniture; some of it is also used to make utensils and for wood turning. The seeds are edible and produce oil that is extracted; the essential 'torreya oil' is extracted from the aril.
Conservation Status
Global status
Endagered B1ab(iii,v)+2ab(iii,v)
Global rationale
This variety has an extent of occurrence of only 3580km² and an area of occupancy of 384km², and is known from about ten locations and because the wood is highly sought after there is assumed to be continuing decline in mature individuals despite the logging ban and also in the quality of the habitat (human disturbance has been seen in nature reserves – Yong Yang pers. comm. 2010).
Global threats
Over-exploitation, habitat degradation, poor regeneration. Despite the logging ban it is likely that off-take is continuing because the wood is extremely popular.
Conservation Actions
Some subpopulations occur (partly) within protected areas.
