dead cedar tree

Asked July 29, 2020, 9:50 AM EDT

What disease is killing cedar trees in this area?
if it is a fungus or something in the soil, will it attack a replacement tree?
Would a Monterey Cypress be more resistant and suitable as a replacement?

Lincoln County Oregon

Thanks for your questions.
There have been reports throughout Oregon and Washington over the past couple of years about dying western redcedar. It is believed to be caused by environmental conditions, a form of abiotic damage (in other words, probably not a disease caused by a fungus).This may be what you are seeing in Lincoln County, although it's hard to make a diagnosis without seeing any damage. Do you have pictures of the damage you can share? For more about this decline, check out this information courtesy of Washington State University: https://ppo.puyallup.wsu.edu/plant-health-concerns/redcedar/.

If you are interested in planting other tree species to replace your western redcedars, there are a few things to consider. For example, where will you be planting these trees? In a small woodland area or in your front yard? What purpose are you planting? For shade around your house, or will this be a reforestation effort? Are you interested in planting native Oregon trees? To help you decide which trees to plant, you can read this great resource by OSU Extension "Selecting, Planting, and Caring for a New Tree" https://catalog.extension.oregonstate.edu/sites/catalog/files/project/pdf/ec1438.pdf.
