CEGL003450 Betula occidentalis - Celtis laevigata var. reticulata Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Water Birch - Netleaf Hackberry Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 408 and 451 m (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, Celtis laevigata var. reticulata, Sambucus nigra ssp. cerulea, and Prunus virginiana 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.

Floristics: These shrublands are characterized by a very diverse, tall-shrub layer, with Betula occidentalis (averaging 50% cover), Philadelphus lewisii (42%), Celtis laevigata var. reticulata (40%), Sambucus nigra ssp. cerulea (= Sambucus caerulea) (13%), and Prunus virginiana (22%) making up most of the fairly dense shrub cover. Other shrubs are generally not very important. Forb and grass cover is low, although exotics 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).

Environmental Description: Stands occur between 408 and 451 m (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.
Geographic Range: Currently, this is very locally distributed in Hells Canyon of Oregon, and may occur in adjacent areas of Idaho and Washington, but has not been reported from there.
