Western Redcedar. In addition to its beauty and practical uses, no other tree in the Pacific Northwest has such a tremendous cultural value as the WRC, known to most Americans as “cedar” (even though it does not belong to the genus Cedrus).Coastal Washington, Oregon, Northern California, and Alaska used to be covered with WRC forests, and WRC trees of truly . Eastern redcedar is a dioecious species, meaning it has male and female plants, and the trees reach sexual maturity at about 10 years of age. The seed is borne in a green to greenish-white to whitish-blue cone appearing like berries on the tree and are usually found in heavy amounts, but only on the female trees.

Although total C storage increases in Eastern redcedar-invaded areas, the shift from belowground to aboveground C storage increases the likelihood of rapid losses in aboveground C following disturbance (e.g. drought, wildfire, .

Western Red Cedar (Thuja plicata) KINGDOM Plantae PHYLUM Coniferophyta CLASS Pinopsida ORDER Pinales FAMILY Cupressaceae Western Redcedar is another of the dominant trees in westside forests of the Pacific Northwest. These trees can grow to huge sizes, over 60 meters tall with a trunk diameter of over 4 meters.
a protective berry-like cone around the seeds. These cones (berries) change colors from green to white to blue. Each cone contains one to four seeds. There are approximat to 43, cleaned and dried seeds per pound (Lawson ).

Seed Orchards The production of genetically improved eastern redcedar presents some unique problems in selec- tion and breeding. There is no record of seed orchard establishment for the species.
While eastern red- cedar can be propagated from cuttings with some measure of success, clonal propagation by grafting is the common horticultural practice. Tsuga mertensiana (Bong.)Carr. Mountain Hemlock.

You can write a book review and. Eastern redcedar invasion is an accelerating progression. The first trees colonize the most favorable sites, usually north-facing slopes. As these trees mature and begin to produce seed, more trees establish and add to the local seed rain.
With more and more seed available, trees eventually appear on less favorable landscape positions. Thuja plicata is one of two Thuja species native to North America, the other being Thuja species name plicata derives from the Latin word plicāre and means "folded in plaits" or "braided," a reference to the pattern of its small leaves.

We hypothesize 1) that there will be a negative relationship between redcedar cover and living ground cover; i.e. as redcedar cover in an area increases; living ground cover in the general vicinity will decrease.
