One of the most iconic trees of the Pacific Northwest has been showing signs of distress for years. Western redcedars are a water-loving tree, and it appears that drought and rising temperatures may be impacting their health. Columbia Insight previously reported on the results of a two-year study on the dieback of Western redcedar trees by the Oregon Department of Forestry, the Washington Department of Agriculture and the U.S. Forest Service. Joey Hulbert leads a citizen-science research project at Washington State University collecting data on western redcedars throughout their range. Christine Buhl is a forest entomologist at the Oregon Department of Forestry and a co-author of a recently published report on the dieback of Western redcedar trees.
