Name: Betula occidentalis - Celtis laevigata var. reticulata Shrubland
Reference: Western Ecology Working Group of...
Description: This is a unique association described from three plots in Hells Canyon, and is known from other river canyons in the inland Pacific Northwest. Stands occur between 1340-1480 feet elevation, generally along major rivers or in broad valleys, at the base of canyon walls near stream channels, where the shrublands follow seeps or seasonal draws upslope. These shrublands are characterized by a very diverse, tall-shrub layer, with Betula occidentalis (averaging 50% cover), Philadelphus lewisii (42% cover), Celtis laevigata var. reticulata (40% cover), Sambucus caerulea (13% cover), and Prunus virginiana (22% cover) making up most of the fairly dense shrub cover. Other shrubs are generally not very important. Forb and grass cover is low, although Bromus tectorum and Anthriscus caucalis are usually found in disturbed sites. Native understory species include Galium aparine, Urtica dioica, Tonella floribunda, and Heracleum maximum (= Heracleum lanatum).
