Forest Composition

The dominant tree of the Magnificent Forest is Douglas Fir. Western red cedar, Bigleaf maple and Pacific Madrone are also well-represented. Western Hemlock is found mainly toward the northern end of the peninsula. The shrub understory is composed largely of salmonberry, thimbleberry, elderberry, Indian plum, hazelnut, sword fern, and Cascade Oregon grape. The abundance of madrone, both in the forest and in the developed southern part of the park, indicates a well-drained, relatively dry site. The Bailey Peninsula is one of the few sites in Seattle where bedrock reaches the surface. The shallow soils overlaying the bedrock combined with the topography of the peninsula contribute to good drainage and dryness.
