Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA PINOPSIDA PINALES PINACEAE

Scientific Name: Picea glehnii
Species Authority: (F.Schmidt) Mast.
Common Name/s:
English Sakhalin Spruce
Synonym/s:
Abies glehnii F.Schmidt

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-12-14
Assessor/s: Katsuki, T., Farjon, A. & Luscombe, D
Reviewer/s: Thomas, P. & Christian, T.
Justification:
Despite extensive logging of this species in the northern part of its range (Sakhalin Island), Picea glehnii is widespread and common in Hokkaido where the largest subpopulations occur. The small subpopulation in Honshu could be susceptible to events like fire, but even the loss of this would not affect the status of the species globally. At this stage, it remains Least Concern.

Population: Despite some past reduction, the overall population trend is thought to be stable.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Picea glehnii occurs from near sea level in the north to 1,650 m a.s.l. on Hokkaido, on N Honshu in a restricted area between 1,000 m and 1,100 m a.s.l. It usually grows on rocky, north- or northwest-facing mountain slopes with podzolic soils; it has also been recorded from ultrabasic, heavy metal yielding volcanic soils. The climate is cold, moist maritime, with abundant precipitation all year, increasing sharply with elevation to more than 1,500 mm annually. It grows in pure stands, or mixed with Picea jezoensis and/or Abies sachalinensis; at lower elevations broad-leaved trees, e.g. Ulmus japonica, Tilia maximowicziana and Acer pictum become important constituents of the forest in many places. Here Taxus cuspidata mixes with the Spruces and the broad-leaved trees
Systems: Terrestrial

Threats [top]

Major Threat(s): Logging has had a significant impact on Sakhalin Island with most forests containing this species logged prior to 1945. These areas have also been impacted by repeated fires (Krestov et al. 2011). In Japan conversion of native forests to plantations has had a limited effect.

Conservation Actions [top]

Conservation Actions: The small population in Honshu (ca. 200 mature trees) is in a protected area. It is also recorded from protected areas in Hokkaido. Very few protected areas currently exist on Sakhalin and it is uncertain if this species occurs within them.
