A3566 Elaeagnus angustifolia Ruderal Riparian Scrub Alliance
Type Concept Sentence: This alliance is dominated by the introduced tree species Elaeagnus angustifolia with a variety of native and introduced species in the shrub and herbaceous layers. It is a widespread woodland alliance found throughout much of the southwestern United States. It is a naturalized species whose seeds are spread by birds. Stands tend to be small and linear and occur in a variety of native habitats, particularly more mesic ones, such as near streams and rivers, upland basins and drainages.
Common (Translated Scientific) Name: Russian-olive Ruderal Riparian Scrub Alliance
Colloquial Name: Ruderal Russian-olive Riparian Scrub
Hierarchy Level: Alliance
Type Concept: This wooded alliance is dominated by the introduced tree species Elaeagnus angustifolia with a variety of native and introduced species in the shrub and herbaceous layers. Additional associated species have not been documented. The alliance is widespread and found throughout much of the southwestern United States. It is a naturalized species that has been widely planted in hedgerows for windbreaks. It has since spread (by birds distributing their seeds) to a variety of native habitats, particularly more mesic ones, such as near streams and rivers. Stands tend to be small and linear.
Diagnostic Characteristics: Woodlands dominated by Elaeagnus angustifolia.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Often a co-inhabitant with tamarisk but forms woodlands and stands in slightly less wet and less frequently flooded areas than tamarisk.
