Sitka spruce's natural range is a narrow strip of land along the
northern Pacific coast from south-central Alaska to northern California.
Its widest distribution (130 miles [210 km] inland) occurs in
southwestern Alaska and northern British Columbia. Its southern
boundary is defined by a disjunct population in Mendocino County,
Sitka spruce has been extensively introduced into the British Isles
The currently accepted scientific name of Sitka spruce is Picea
sitchensis (Bongard) Carriere (Pinaceae) [28
Species within the genus Picea form hybrid swarms at the interface of
their ranges. Sitka spruce naturally hybridizes with white spruce (P.
glauca) to produce Lutz spruce (Picea X lutzii Little) [22
It is often difficult to identify Picea X lutzii by morphological
chacteristics in stands with low levels of introgression [23
Sitka spruce in plantations will also hybridize with Yezo spruce (Picea
jezoensis), Serbian spruce (P. omorika), and Engelmann spruce (P.
