In the last decade, Swiss needle cast (SNC), caused by the native fungus Phaeocryptopus gaeumannii, has severely damaged Douglas-fir in the Coast Range of western Oregon. The primary impact of the pathogen on Douglas-fir (the only susceptible tree species) is premature loss of foliage, which results in significant reduction in tree growth. Recent reduction in volume growth from SNC in western Oregon likely exceeds 100 million board feet per year.Publication Notes
