Passage: Sitka spruce is native to the west coast of North America, with its northwestern limit on Kenai Peninsula, Alaska, and its southeastern limit near Fort Bragg in northern California.  It is closely associated with the temperate rain forests and is found within a few kilometers of the coast in the southern portion of its range. North of Oregon, its range extends inland along river floodplains, but nowhere does its range extend more than 80 km (50 mi) from the Pacific Ocean and its inlets. Sitka spruce also grows on the west coast of Norway, where it is considered an invasive species.
