Name: Thuja plicata / Aralia nudicaulis Forest
Reference: NatureServe Biotics 2019
Description: This is a late-seral evergreen conifer forest found in the mid elevations in the Okanogan Highlands east of the Kettle Mountain crest in Washington and British Columbia, with outliers in Montana. It appears on stream terraces representing xero-riparian conditions and on lower slopes and benches, mostly below 1065 m (3500 feet) in Washington and 1220 m (4000 feet) in Montana. Its name reflects a potential vegetation. The existing vegetation is dominated by a closed canopy of <i>Picea engelmannii, Thuja plicata</i>, and <i>Pseudotsuga menziesii</i> trees. The undergrowth can contain scattered tall deciduous shrubs such as <i>Acer glabrum</i> and <i>Alnus viridis ssp. sinuata</i>. The short and dwarf-shrub layers have both greater diversity and cover than the tall-shrub layer, with <i>Linnaea borealis</i> and <i>Cornus canadensis</i> being the most constant and having appreciable coverages. The herbaceous component is characterized by a rich assortment of mesic site forbs, such as <i>Aralia nudicaulis, Clintonia uniflora, Galium triflorum, Maianthemum stellatum, Tiarella trifoliata</i>, and <i>Prosartes hookeri</i>; graminoids, with the exception of the highly constant <i>Bromus vulgaris</i> (or <i>Bromus ciliatus</i>), are a minor element.
