The Duwamish Greenbelts Management Plan identified primary management issues for the Duwamish Greenbelts Reforestation Project, some of which include lack of forest complexity, low forest age and density, and low native plant diversity/high invasive plant occurrence. Several prescriptions outlined tasks for managing the vegetation of the Duwamish, which include managing hazard trees, thin dense forest stands, and identifying/creating canopy gaps.
The prescription area is a 24-acre hardwood-dominated forest site to be treated by creating canopy gaps in combination with other restoration practices in order to promote site conditions conducive to conifer establishment and increased native forest diversity. Attendees will understand the reasoning behind, use of, and lessons learned in thinning and other techniques used on this urban forest restoration project.

Attendees will understand the reasoning behind, use of, and lessons learned in thinning used on this urban forest restoration project.
Attendees will learn what site conditions are conducive to conifer establishment and increased native forest diversity.
Attendees will learn how site characteristics, such as low forest complexity, age, and diversity, and high invasive plant occurance can influence what restoration efforts are successfully undertaken.
