Common Plant communities:
White spruce communities are undefined. White spruce occasionally replaces Lutz spruce in the following community:

Many of these wetlands occupy narrow slopes above a large lakebed complex located between Kalifonsky Beach Road and the Sterling Highway near Kasilof. White spruce mixing with black spruce (Picea mariana) is the most common complex (SMG or SGM), and a few of these also occur at the edge of the interlobate moraine, between Soldotna and Sterling. A single thinleaf alder (Alnus incana ssp. tenuifolia) / white spruce complex lies along the slope of a smaller lakebed complex near the City of Kenai.
