Trout Lake Natural Area Preserve
This 2,014-acre preserve meets several important statewide conservation goals. It is one of only seven areas in Washington that still grand fir - Douglas-fir forest and it supports the second largest population in the state. The entire site, including the marsh habitat and adjacent forested uplands, is one of the highest quality mid-elevation wetland ecosystems in south-central Washington, providing vital habitat for hundreds of wildlife species. Over 150 species of birds have been recorded on the site, including many neotropical migratory species of conservation concern. It is part of the Pacific Flyway, providing important feeding and resting habitat for migratory waterfowl such as redhead ducks, cinnamon teal, hooded mergansers and pied-billed grebe. Several rare plant species are found in seasonal wetland and oak woodland habitats on the preserve.
