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.
Systems: Terrestrial

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.
