Despite Abies mariesii being restricted to high elevations, its distribution and regeneration appear to guarantee the survival of this species, so that it is therefore not considered threatened under the Red List Criteria. There is no evidence of a current threat to the species, hence it is assessed as Least Concern.
|Previously published Red List assessments:|
|Range Description:||Endemic to Honshu, Japan.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||The species forms pure stands on mountain slopes. The population is thought to be stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||A species of the high mountain sides and ridges in the upper montane and subalpine zones, occurring commonly between 1,000 m and 2,800 m a.s.l. (as low as 750 m in N Honshu). The soils are mostly derived from volcanic rock, usually podzolic and slightly acid or neutral, well drained, and moderately moist (mesic). The climate is cold, with abundant winter snow and cool, moist summers, the annual precipitation exceeds 2,000 mm in the mountains nearest to the Sea of Japan. Frequent typhoons are a destructive force reducing the maximum age of trees. Abies mariesii forms sometimes pure forests near the tree line, but is more common in mixed (coniferous) forests with e.g. Abies veitchii, Tsuga diversifolia, Picea jezoensis var. hondoensis and/or undergrowth of Pinus pumila and Juniperus communis var. nipponica, the latter two especially abundant on ridgetops. Common broad-leaved trees are Betula ermanii, Sorbus commixta, and Acer spp. In many previously disturbed areas with deep, fine textured soil, e.g. volcanic ash, there is a dense cover of small bamboo (Sasa paniculata and S. nipponica), which excludes most other plants (Franklin et al. 1979).|
|Continuing decline in area, extent and/or quality of habitat:||No|
|Generation Length (years):||50|
|Use and Trade:||This species of fir has little value as a timber tree because it grows at high altitude and mostly in inaccessible localities. In horticulture it is rather uncommon despite its attractive dark green foliage leaves and contrasting white stomatal bands underneath. It is not at all tolerant of droughts and performs best in cool, wet conditions but on light, well-drained soils. It is mostly restricted to collections in botanic gardens and arboreta.|
|Major Threat(s):||No specific threats have been identified for this species.|
|Conservation Actions:||No specific conservation actions have been targeted at this species. It is known from several protected areas.|
