    Description

    The distribution of a forest decline of yellow-cedar (Callitropsis nootkatensis (D. Don) Ă–rsted) has been documented in southeast Alaska, but its occurrence in British Columbia was previously unknown. We conducted an aerial survey in the Prince Rupert area in September 2004 to determine if yellow-cedar forests in the North Coast Forest District of British Columbia were experiencing a similar fate as in nearby Alaska. Numerous large areas of concentrated yellow-cedar mortality were found, extending the known distribution of the decline problem 150 km south of the Alaska-British Columbia border. The forests with the most concentrated tree death occurred at 300 to 400 m elevation, frequently on south aspects. The appearance of these forests including proximity to bogs; mixtures of dying, recently killed, and long-dead trees; and crown and bole symptoms of dying trees were all consistent with the phenomenon in southeast Alaska.
