This research focuses on Swiss needle cast, a foliage disease specific to the Douglas fir caused by a fungal pathogen. Symptoms include chlorotic needles and decreased needle retention, resulting in sparse crowns and reduced diameter and height growth. The mission of the SNCC is to conduct research to enhance Douglas-fir productivity and forest health in the presence of Swiss needle cast and other diseases in coastal forests of Oregon and Washington.
