dendro 4

Pseudotsuga menziesii

largest, most abundant tree in the cascades, where its harvest is critical to sustained yield forestry

Abies magnifica

shade tolerant climax of the subalpine zone in the Sierras

Pinus lambertiana

largest Pinus in the world

Alnus rubra

most valuable hardwood in the PNW, pioneer on stream terraces and bottomlands in PNW fogbelt, nitrogen-fixer

Calocedrus decurrens

with P. ponderosa, forms the lower timberline in the Sierras

Pinus monticola

moderately shade tolerant dominant following fire in the inland empire, problems with blister rust and mountain pine beetles

Pinus contorta

pioneer especially following fire in the montane and subalpine zones of the Sierras, occurs over the greatest elevational range in the western US, known as "shore pine"

Pinus ponderosa

primary timber species in the interior basin

Chamocyparis lawsoniana

most restricted geographical range of above, but varieties are widely planted, one of most valuable conifers for timber

Sequoiadendron giganteum

tolerates feezing temperatures better than S. sempervirens, the largest living thing on the earth (volume of living tissue), restricted to Sierras, thick bark makes it fire resistant
