Habitat and Ecology

Habitat and Ecology
Picea alcoquiana is a scattered mountain species, occurring at elevations from 700 m to 2,180 m (var. acicularis between 1,200 m and 1,950 m) a.s.l. The soils are of volcanic origin and podzolic. The climate is cool, with cold, snowy winters, and wet (annual precipitation 1,000 mm to 2,500 mm), while typhoons are frequent. The forests on these mountains are mixed coniferous, with Picea jezoensis subsp. hondoensis as the most common of the spruces, Tsuga diversifolia and Larix kaempferi, both also common, Pinus parviflora and Abies veitchii in some areas, A. mariesii usually at higher elevations, and broad-leaved trees, e.g. Betula ermanii, B. grossa, Sorbus commixta, Quercus mongolica var. grosseserrata, Alnus hirsuta var. sibirica, and Prunus maximowiczii.

Justification
The species as a whole, like its most common and widespread nominate variety, does not meet the criteria for a threatened category, but may warrant listing as threatened if the decline due to logging continues. Although its area of occupancy has been reduced due to logging, this is not inferred to have exceeded 30% and it therefore does not meet the criteria (A2d) for a threatened category.

Threats

Major Threats
The main threat to the species, past and present, is logging. This has particularly affected the rarer varieties with their very limited extents of occurrence and areas of occupancy.
