Conditions/Habitat/Kind of Forest: The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay and nutritionally poor soils. The plant prefers acid and neutral soils and can grow in very acid and very alkaline soils. It cannot grow in the shade. It requires moist or wet soil.

Ecological Interactions: No serious insect or disease problems. Species of spruce are generally susceptible to a number of insect problems, the most common of which are spider mites, aphids, bagworms and borers. Spruces are also generally susceptible to a number of fungal diseases, particularly in humid climates.
Conservation Status-US/ World Wide: This tree is not currently listed as threatened or endangered.  Although the subalpine coniferous forests where the tree is found have been largely cut down, relatively large intact examples still remain. For example, Mt. Daisetsu National Park in Japan covers several volcanic mountains with extensive spruce and fir forests on its slopes.  Unfortunately, protection of the plants from poaching, construction of roads, and tourism has not been very effective.
Uses (Human):
A specimen tree which is effective when used in a large scale planting for lawns, parks, golf courses, highways or near large buildings. Wood - beautifully grained. Used for pianos, violins, interiors of buildings etc. It is also valued for its use in the pulp industry to make paper. Used as a flavoring. The central portion, when roasted, is sweet and syrupy.
Inner bark - dried, ground into a powder and then used as a thickener in soups etc or added to cereals when making bread. An emergency food, it is only used when all else fails. A refreshing tea, rich in vitamin C, can be made from the young shoot tips.
