Title:  The Impacts of Forest Management on Washington State's Forested Wetlands: Assessing Disturbance Trends and Ownership Distribution for the Conservation and Climate Resilience Purposes Committee Members: L. Monika Moskal Meghan Halabisky Clare Ryan Abstract: Washington State’s forested wetland are essential sources of environmental provisioning, offering habitat support, water purification, and carbon sequestration. However, the interaction between these wetlands and forest management policies has become an increasingly concerning issue. Historically, the lack of accuracy of wetland mapping has impeded investigations into this complex relationship.

In combination with temporal policy analysis that have impacted forested wetlands, this research sheds light on the long-term impacts of policies on disturbance patterns.

Join the Friends of Seattle’s Olmsted Parks on the final walking tour of Seattle’s Olmsted Brothers parks and parkways this summer!

Features of the Olmsted Brothers’ plans that are most evident today include Lake Washington Boulevard, Azalea Way, the Stone Cottage and Stone Overlook, and the pond in the Japanese Garden.
