Douglas-fir disease spreading along Oregon and Washington coasts | OregonLive.com: "A fungal disease attacking Douglas-fir trees along the Pacific Northwest coast is intensifying and may be linked to a warmer climate and extensive planting of Douglas-fir on logged tracts, new Oregon State University research suggests.
The epidemic of Swiss needle cast stunts growth in both older and younger trees and appears to be unprecedented over at least the past 100 years, OSU researchers Bryan Black, David Shaw, and Jeffrey Stone concluded."
