Justification:
Widely distributed but almost impossible to establish from herbarium collection data where it is truly indigenous (growing in the wild) and where it has been introduced and planted. One can take the view (as the Chinese and Japanese mostly do) that such a taxon is not threatened with extinction even if its wild (sub)populations are greatly reduced. Since under IUCN criteria we are bound to assess the populations that occur in their natural habitat this species must remain Data Deficient.

History:

1998	–	Data Deficient
1998	–	Data Deficient (Oldfield et al. 1998)
1998	–	Near Threatened

Geographic Range [top]

Range Description:	Southern China, Taiwan, and the southern islands of Japan. The species appears in populations in the northern end and southern tip of Taiwan, separated by the central range of mountains. Its distribution is imperfectly known: the range of natural occurrence (EOO) is probably substantially less extensive than the distribution given in for example the Atlas of the Gymnosperms of China (Ying et al. 2004) which makes no distinction between introduced/planted and occurrence in the wild.
Countries:	Native: China; Japan (Nansei-shoto); Taiwan, Province of China

Population Trend:	Unknown

Population Trend:

Unknown

Habitat and Ecology [top]

Habitat and Ecology:	An important timber species occurring in moist forest (mixed mesophytic evergreen forest and mixed mesophytic deciduous forest) at various elevations.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Selective logging, habitat disturbances, deforestation. There is concern for populations on Shikoku and Kyushu Islands in Japan because of the levels of exploitation. Occurring in lowland mixed evergreen forest, the species has come under threat from habitat declines. Whole plants are also dug up for the horticultural trade.
