Picea sitchensis/Vaccinium ovalifolium

(Sitka spruce/early blueberry)

(PICSIT/VACOVA; 5 sites)

IA1a. Closed needleleaf forest, Sitka spruce


Vegetation- Picea sitchensis (Sitka spruce) dominates the tree layer with

Tsuga heterophylla (western hemlock) often occurring as a minor associate.

Vaccinium ovalifolium (early blueberry) is the most constant and abundant

shrub. Rubus spectabilis (salmonberry), Echinopanax horridum (devilís club),

and Alnus crispa ssp. sinuata (Sitka alder) may be common associated tall

shrubs. Low and dwarf shrubs are absent. Undergrowth species with high

constancy but low cover include Rubus pedatus (fiveleaf bramble), Cornus

canadensis (bunchberry), Tiarella trifoliata (foamflower), Lycopodium

annotinum (stiff clubmoss), and Streptopus amplexifolius (twistedstalk).

Physical setting- Sitka spruce/early blueberry is a minor type that has been

sampled on beaches and flood plains. It occurs on flat to nearly flat

surfaces at less than 50 feet elevation.
