Name: Thuja plicata / Adiantum pedatum Forest
Reference: Western Ecology Working Group of...
Description: This association is described based on data collected on 30 plots located in northern Idaho in the Clearwater River watershed. The association occurs on moist, low to moderately sloped sites in mid, lower, to toeslope positions at moderately low elevation (generally <3000 feet) between the St. Joe and Selway rivers, Idaho. Stands are characterized by a lush understory dominated by Adiantum pedatum and Polystichum munitum. Adenocaulon bicolor, Asarum caudatum, Clintonia uniflora, and Coptis occidentalis and many other species form a rich herbaceous layer. Wet-site species such as Trautvetteria caroliniensis and Senecio triangularis may occur with low abundance but are characteristically less abundant than on adjacent Thuja plicata / Athyrium filix-femina sites. Thuja plicata is typically dominant in late-seral stands. Tsuga heterophylla is present in some stands. Abies grandis is often the dominant tree in early and mid-seral stands.
