CEGL000792 Celtis laevigata var. reticulata / Philadelphus lewisii Wet Scrub
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Netleaf Hackberry / Lewis'' Mock Orange Wet Scrub
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a riparian shrubland or short woodland community known only in the vicinity of the common border of Oregon, Washington, and Idaho along the Snake River and tributaries. This type is typically found on upper stream terraces, although it can occur on toeslopes or in the active floodplain. Generally this association follows the distribution of Alnus rhombifolia but extends into drier climates and riparian sites than Alnus rhombifolia. Incomplete surveys indicate this association may occur or occurred in the dry end (east) of the Columbia River Gorge in Washington. Short Celtis laevigata var. reticulata trees, 3 to 6 m (10-20 feet) tall, form a dense to open canopy with shrubby undergrowth with Philadelphus lewisii. Shrub layer often contains Sambucus nigra ssp. cerulea, Rosa woodsii, or Rosa nutkana. Toxicodendron rydbergii is more abundant on moist sites and with more sampling may represent a different association. Exotic herbaceous plants are frequent in this association. Bromus tectorum is common and can be very abundant on recently disturbed sites. The exotic herb Anthriscus caucalis is the most common forb species. Associated herbaceous species are typically drier riparian species and often are increasers with ground disturbance. As conceptualized, this type currently includes all Celtis laevigata var. reticulata communities with Philadelphus lewisii that are associated with riparian environments. It is distinct from the more open upland/toeslope ~Celtis laevigata var. reticulata / Pseudoroegneria spicata Wet Scrub (CEGL001085)$$.

Environmental Description: This type is typically found on upper stream terraces, although it can occur on toeslopes or in the active floodplain. Generally this association follows the distribution of Alnus rhombifolia but extends into drier climates and riparian sites than Alnus rhombifolia. Incomplete surveys indicate this association may occur or occurred in the dry end (east) of the Columbia River Gorge in Washington.
Geographic Range: This association is reported from the Hells Canyon area of the Snake River and its tributaries in Idaho, Oregon and Washington. It is reported as disjunct in the east end of Columbia River Gorge of Washington, and in the lower portions of the John Day River Canyon in Oregon. Its occurrence in Idaho is uncertain.
