Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-12-16
Assessor(s): Katsuki, T., Zhang, D, Rushforth, K. & Farjon, A.
Reviewer(s): Thomas, P. & Page, C.
Although there has undoubtedly been a decrease in Abies firma's area of occupancy over the past two or three generations, this is from a large basis and does not cause current concern for the species. Accordingly it is assessed as Least Concern

Habitat and Ecology [top]

Habitat and Ecology:Abies firma occurs on hills and in mountains of southern and central Japan, at elevations between 50 and 1,900 m a.s.l. (commonly 300 and 1,000 m). The soils are various mountain soils of volcanic origin or alluvial, and mesic. The climate is moist or wet, cool in the north of its range and warm temperate in the south, with annual precipitation above 1,000 mm. This species is a constituent of mixed forests (rarely in pure stands on dry sites) with e.g. Fagus crenata, F. japonica, Castanea crenata, Carpinus laxifolia, Quercus spp., Tsuga sieboldii, Pinus parviflora, P. densiflora, Pseudotsuga japonica, Abies homolepis, Cryptomeria japonica, Sciadopitys verticillata, Chamaecyparis obtusa, Torreya nucifera and Picea jezoensis ssp. hondoensis.
Generation Length (years):50

Use and Trade [top]

Use and Trade: Momi Fir is the most common and widespread fir in southern Japan and is regarded as an important timber tree. Its wood is light, soft and straight-grained and easily worked, but requires careful seasoning to prevent warping. It is used for carpentry making indoor framing, flooring, joinery, crates, boxes, etc., but the greatest quantities of its timber are converted to paper pulp. In plantation forestry it is only common in Japan, where old growth stands of this large fir have mostly been logged. Elsewhere, it is only used as an ornamental tree or planted in collections in arboreta and botanic gardens, requiring a climate with mild winters and abundant rainfall.

Threats [top]

Major Threat(s): Natural forest areas near towns are declining so there is an on-going risk of loss of forest habit, taking Abies firma with it.

Conservation Actions [top]

Conservation Actions: Included in some protected areas as part of wider natural forest protection.
