Abies sachalinensis var. nemorensis
|Scientific Name:||Abies sachalinensis var. nemorensis|
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Taxonomic Notes:||In Japan, Abies sachalinensis (F. Schmidt) Mast. var. nemorensis Mayr is considered a synonym of Abies sachalinensis (F. Schmidt) Mast. var. sachalinensis|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Assessor(s):||Katsuki, T., Rushforth, K. & Zhang, D|
As this variety is not distinguished in Hokkaido (the main part of its range), there is no detailed information beyond what is available for the typical variety. Its status on the Sakhalin Islands is also unknown. Due to insufficient information this taxon is assessed as Data Deficient.
|Range Description:||Recorded from Japan: Hokkaido;and the Russian Far East: Sakhalin.|
Native:Japan (Hokkaido); Russian Federation (Sakhalin)

|Population:||The population trend is unknown.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Probably similar to that of the typical variety which occurs from near sea level on the coast to an elevation of 1,650 m a.s.l. in the mountains. The soils are well drained but moist throughout the year, due to abundant precipitation in a cool to cold, maritime climate. In the north of its range it is more common at elevations between 800 m and 1,100 m, where it is mixed with Picea jezoensis, P. glehnii, Larix gmelinii var. japonica or Pinus pumila at the highest limit of trees. At lower elevations pure stands occur, below 800 m broad leaved-trees, e.g. Betula ermanii, Acer spp., Quercus spp., Castanea crenata, Kalopanax septemlobus, and Magnolia hypoleuca become more abundant..|
|Continuing decline in area, extent and/or quality of habitat:||No|
|Generation Length (years):||50|
|Use and Trade:||This variety is mainly logged for the manufacture of wood pulp used in the paper industry; its timber is of low quality for construction and carpentry. Because there are few tree species to plant in the subarctic zone, the Sakhalin Fir is planted for wood production at many places in Hokkaido. As an amenity tree it is sometimes used outside the cool to cold maritime climate of northern Japan and the Russian Far East. It is in cultivation in botanic gardens and arboreta in Russia, northern Europe and New England, U.S.A., but rarely survives to maturity in countries with mild winters, where it will not go into prolonged winter dormancy and is susceptible to spring frosts.|
|Major Threat(s):||Large scale logging of this variety (and the species) took place in Hokkaido between 1980 and 2000. Such exploitation led to a decline in old growth forests but has now ceased. Its status on Sakhalin Island is uncertain although it is likely that old growth forest have also declined after widespread logging.|
|Conservation Actions:||This variety is known from several protected areas in Hokkaido.|
