- The Spencer Island Unit is a flat, grassy intertidal complex ringed by mixed forest, located in the Snohomish River estuary. This unit offers waterfowl hunting, hiking, and wildlife viewing opportunities. A 1-mile, elevated trail is a special feature. The island is jointly-owned/managed by WDFW and the Snohomish County Parks and Recreation Department. In 2005, an act of nature breached a dike on the WDFW property on the northwest side of the island, restoring tidal influence to the area. WDFW and its partners are working together to continue restoration of the estuarine system.
- Oak Patch Natural Area Preserve (dnr.wa.gov)
This 17 acre site preserves an Oregon white oak woodland and an Oregon white oak-Douglas-fir mosaic which is extremely unusual on the Kitsap Peninsula, and represents a vanishing woodland community in the Puget Trough. Spring wildflowers such as fawn lilies, chocolate lilies and camas lilies thrive on this site, along with populations of the Puget fritillary and Shelton pine elfin butterflies, and the western toad.
- Snoqualmie Wildlife Area (wdfw.wa.gov)
The approximately 2,840 acres of Snoqualmie Wildlife Area consists of six management units located in Snohomish and King counties.
