DENDRO GROWTH

more common in mixed stands of the subalpine zone with Abies magnifica, Larix lyallii, Tsuga mertensiana; replaced by A. magnifica if fire suppressed; through Yosemite National Park, etc.

Pinus contorta

most valuable wood of western pines but not as abundant as other commercial pine species

Pinus lambertiana

quite similar to eastern white pine in many silvical

Pinus lambertiana

a principal cellulose source for rayon; leading export species to Japan. 10% of standing timber in PNW

Thuja heterophylla

subclimax of the superhumid fog belt along the coast from n. California to southeastern Alaska (where annual rainfall is about 12 ft and hard freezes are uncommon – this is the temperate rainforest); best growth on the Olympic Peninsula

picea stichensis

very tolerant, slow-gowing, large (to 250 ft. tall and 21 ft. dbh), long-lived climax on mesic (moist) sites at low elevations; best growth in and near Olympic Peninsula

Thuja plicata

moderately tolerant, large, relatively long-lived pioneer following disturbance (especially fire) best growth in the Inland Empire

Pinus monticola

semi-deliquescent form despite lack of shade tolerance

Pinus sabiniana

subclimax species of moist sites in fog belt, especially low, wet streamsides highly restricted natural range

Chamaecyparis lawsoniana

almost all export wood shipped to Japan where wood is used as substitute for the revered Japanese C. obtusa

Chamaecyparis lawsoniana

tolerant, slow-growing, long-lived climax on dry sites throughout montane zone

calocedrus decurrens

forms the lower timberline with Calocedrus decurrens above the foothill zone best growth and tallest throughout entire range on relatively moist but well-drained western slopes of the Siskiyou and Sierra Mountains of s. Oregon and California

Pinus ponderosa
