Name: Platanus wrightii Temporarily Flooded Forest Alliance Reference: Western Ecology Working Group of... Description: This riparian forest alliance occurs along perennial or seasonally intermittent streams in the southwestern U.S. Stands occur in narrow stream valleys, on gently sloping alluvial terraces. These vegetation types require reliable surface flow during the winter-spring months, they are periodically inundated during spring runoff and generally are found along small, perennial streams. The soils are depositional and silty loam in texture. Vegetation within this alliance is characterized by a closed forest canopy dominated by the broad-leaved cold-deciduous tree Platanus wrightii. Fraxinus velutina and Juglans major are common codominants. Populus fremontii often is an emergent tree from the canopy. The moderately dense tree subcanopy often includes Celtis laevigata var. reticulata, Prosopis velutina, Quercus arizonica, Quercus emoryi, Robinia neomexicana, and Salix gooddingii. The woody vine Vitis arizonica is typically present. The shrub layer is often present and contains several of the following: Rhus trilobata, Toxicodendron radicans, Amorpha fruticosa, and Baccharis salicifolia. The herbaceous layer commonly includes Aristida spp., Bouteloua curtipendula, Carex spp., Eriogonum spp., Gutierrezia sarothrae, Muhlenbergia spp., Elymus elymoides, and Sporobolus cryptandrus. Diagnostic of this riparian alliance is the closed tree canopy dominated by Platanus wrightii, and the brief seasonal flooding and relatively high water tables that occur in these forests.  Accession Code: VB.CC.17985.PLATANUSWRIGHTI Plot-observations of this Community Concept: 0
