CEGL005315 Rosa californica Wet Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: California Wild Rose Wet Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This shrubland is known from the Sacramento River, Suisan Marsh and Pinnacles National Monument, and is expected to occur throughout California. The shrubland is an early-seral community, often found along roads, ditches, edges of drying marshes, riparian areas, washes, and other naturally disturbed or human-impacted areas. This shrubland ranges from less than 0.3 to over 2 m in height. Slopes are low (0-3%), and soils highly variable, from clay, silt loam, to sand. More natural settings are found along riparian areas and around wetlands, where it occurs in narrow strips. Rosa californica is the dominant and characteristic shrub, though Artemisia californica, Baccharis pilularis, Rubus armeniacus, Salix lasiolepis, Salvia mellifera, Sambucus nigra ssp. canadensis, and Symphoricarpos mollis may be equally important. Emergent trees such as Salix laevigata may be present. Herbaceous species may be present as well in an open understory, with many non-natives.

Floristics: Rosa californica is the dominant and characteristic shrub, though Artemisia californica, Baccharis pilularis, Rubus armeniacus (= Rubus discolor), Salix lasiolepis, Salvia mellifera, Sambucus nigra ssp. canadensis, and Symphoricarpos mollis may be equally important. Emergent trees such as Salix laevigata may be present. Herbaceous species may be present as well in an open understory, with many non-natives.

Dynamics:  No Data Available

Environmental Description:  This is an early-seral community in which Rosa californica is dominant and conspicuous, often forming narrow briar patches along levees and roads, riparian areas, washes, lower-lying (drying) portions of marsh (Keeler-Wolf and Vaghti 2000), and other naturally disturbed or human-impacted areas. This shrubland ranges from less than 0.3 to over 2 m in height. Slopes are low (0-3%), and soils are highly variable, from clay, silt loam, to sand. More natural settings are found along riparian areas and around wetlands, where it occurs in narrow strips.

Geographic Range: This association is known from the Sacramento River, Suisan Marsh and Pinnacles National Monument, and is expected to occur throughout California.
