Description

Tree to 40(-50) m tall, with trunk to 1.5 m in diameter. Bark gray, browning and becoming ridged and furrowed with age. Young branchlets hairy in the deep grooves. Buds 4-8 mm long, sparsely resinous or not. Needles arranged straight out to the sides on flower branches but directed upward on high branches bearing seed cones, 2-4.5 long, glossy dark green above, the tips usually sharp-pointed (not notched like its close relatives, hence the scientific name, “entire leaf”). Pollen cones 10-15 mm long, reddish yellow. Seed cones cylindrical, (6-)10-12(-14) cm long, (3-)3.5-4.5(-5) cm across, green (or purplish green) when young, maturing light brown. Seed body 6-8(-10) mm long, the wing up to 1.5 times as long.

Cheju (Quelpart) Island, Korean Peninsula and nearby northeastern China, and extreme southeastern Russian Far East. Forming pure stands or more commonly mixed with other conifers in boreal and mixed forests in dryish mountain valleys; 0-800(-1,500) m. The climate is cold, with wet summers and arid winters with long periods of snow.

 

Conservation Status

Red List Category & Criteria: Near Threatened

Unrestricted logging, especially but not only in the Russian Far East has led to a decline over the last three generations. However, the extent of the decline is estimated to be less than 30%. Consequently Abies holophylla is assessed as Near Threatened. A continued decline could result in a change of category at the next assessment. At higher elevations or in the NE of its range it forms pure stands, or more commonly mixed coniferous forests with Pinus koraiensis, especially in the coastal mountains near the Sea of Japan. In other areas it is a constituent of the northern mixed coniferous deciduous forests, with Abies nephrolepis, Picea spp., Larix gmelinii (var. olgensis) and broad-leaved trees, such as Populus spp., Quercus mongolica, Fraxinus mandshurica, Ulmus spp., and Betula ermanii. Loss of habitat following extensive logging would appear to be the greatest threat, especially when forests are subjected to repeated burning after logging. In Europe it was introduced around 1905, but, although perfectly hardy and ornamental, remains an uncommon tree mainly seen in arboreta and botanic gardens of the northern hemisphere's cooler regions. A proportion of the distribution of this species falls within protected areas, but  the larger part of it is outside such reserves.
