Seward Park Hemlock Tree Monitoring

Main Project Information
Where 5902 Lake Washington Blvd S., Seattle Washington Seattle United States

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!

How to Join

This hemlock monitoring project is still in the development phase, but interested volunteers can sign up to be part of the project at

Required Gear

Volunteers need to be able to use a global positioning system (GPS) device and a map to find the trees and then a ruberic (evaluation guide) to score overall tree health. Seward Park will provide all relevant training.
