Seward Park in Seattle, Washington, needs citizen volunteers to monitor the health of hemlock trees. Some of the hemlocks in Seward Park have annosus root disease, and park officials are worried about them. Researchers are establishing a long-term monitoring plan for 20-30 hemlocks in the park. This will allow them to watch for the progression of the disease on the infected trees and keep an eye out for spreading problems. Fortunately, this project will only take a few hours every few months, so participating is easy!
