Trees looking a little haggard? Blame it on drought stress

Some of Oregon's trees aren't faring so well this spring, especially the Douglas first and other conifers in the northwestern part of the state.  "My best explanation is drought stress," said Brad Withrow-Robinson, a forester with the Oregon State University Extension. "We had a pretty hard end of summer last year - no rain until mid-October - then boom! It was winter."
