Abstract
Abstract Chamaecyparis nootkatensis (D. Don) Spach (yellow-cedar, Alaska yellow-cedar) is an ecologically important and extremely valuable tree species in coastal Alaska. Its ecology, silvics, and methods of management, however, are poorly understood (Harris 1990, Hennon 1995). Chamaecyparis nootkatensis, which is now dying on more than 200,000 hectares (ha) of unmanaged forest in southeast Alaska, is suffering from the most severe forest decline in western North America (Fig. 3.1). In addition, this species has limited successful reproduction in many declining and healthy unmanaged forests in Alaska; numerous searches have failed to locate seedlings (Harris 1990). Forest managers are particularly concerned because C. nootkatensis is not frequently regenerating on sites harvested by logging.
