Name: Thuja plicata / Adiantum pedatum Forest
Reference: NatureServe Biotics 2019
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 &lt;915 m [3000 feet]) between the St. Joe and Selway rivers, Idaho. Stands are characterized by a lush understory dominated by <i>Adiantum pedatum</i> and <i>Polystichum munitum</i>. <i>Adenocaulon bicolor, Asarum caudatum, Clintonia uniflora</i>, and <i>Coptis occidentalis</i> and many other species form a rich herbaceous layer. Wet-site species such as <i>Trautvetteria caroliniensis</i> and <i>Senecio triangularis</i> may occur with low abundance but are characteristically less abundant than on adjacent <i>Thuja plicata / Athyrium filix-femina</i> sites. <i>Thuja plicata</i> is typically dominant in late-seral stands. <i>Tsuga heterophylla</i> is present in some stands. <i>Abies grandis</i> is often the dominant tree in early and mid-seral stands.
