CEGL003392 Fraxinus latifolia / Spiraea douglasii Riparian Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Oregon Ash / Rose Spirea Riparian Forest

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: According to Christy (2004), the habitat of this association is riparian woodland or forest with an open to closed canopy. Fraxinus latifolia is the only tree species present, and stands are characterized by a very dense shrub layer of Spiraea douglasii with little else present except Carex obnupta. Stands may be extensive along floodplains, and some have no doubt developed on abandoned pasture land and old prairie.
