Growing Regions

Alaska-cedar is found in the Pacific Coast mountain ranges from south-central Alaska to southwestern Oregon with isolated groves in the Siskiyou Moutains of northern California [1,23,24]. The eastern edge of Alaska-cedar's range is defined by two disjunct populations: one in the Selkirk Mountains of southeastern British Columbia [33] and one in the Aldrich Mountains of central Oregon [1].


General Information

The scientific name of Alaska-cedar is Chamaecyparis nootkatensis (D. Don) Spach. It is a member of the Cypress family (Cupressaceae) [32]. Alaska-cedar hybridizes with members of the genera Xanthocyparis and Cupressus. The hybrids are as follows [23,24,61]: Chamaecyparis nootkatensis Xanthocyparis vietnamensis Cupressocyparis notabilis (Chamaecyparis nootkatensis Cupressus glabra) Cupressocyparis ovensii (Chamaecyparis nootkatensis Cupressus lusitanica) Cupressocyparis leylandii (Chamaecyparis nootkatensis Cupressus macrocarpa) The Cupressocyparis hybrids have been extensively introduced in Great Britain [23].

Alaska-cedar is listed as a dominant or codominant overstory species in the following publications: A preliminary classification system for vegetation of Alaska [55]. The forest communities of Mount Rainer National Park [17]. A preliminary classification of forest communities in the central portion of the western Cascades in Oregon [9]. Preliminary plant associationa of the southern Cascade Mountain Province [2]. Preliminary plant associations of the Siskiyou Mountain Province [3]. Vegetation and the environment in old growth forests of northern southeast Alaska: A plant association classification [44].
