Common (Translated Scientific) Name: Goodding's Willow - Red Willow Riparian Forest Alliance
Colloquial Name: Goodding's Willow - Red Willow Riparian Forest
Hierarchy Level: Alliance
Type Concept: This alliance consists of riparian woodlands and forests dominated by Salix gooddingii and/or Salix laevigata, either as single-species stands or as mixed stands. Stands may or may not include Populus fremontii, and if they do, it is a minor component relative to dominant overstory canopy species. Other tree species present include Acer macrophyllum, Alnus rhombifolia, Alnus rubra, Celtis laevigata var. reticulata, Fraxinus velutina, Juglans microcarpa, Platanus racemosa, Populus balsamifera, Prosopis glandulosa, Quercus pungens, Salix hookeriana, Salix sitchensis, Sapindus saponaria var. drummondii, and/or Ungnadia speciosa. These stands occur throughout California riparian areas with deep alluvial soils generally restricted to less than 2000 m in elevation.
Diagnostic Characteristics: One of the three nominals has 30% relative cover or combined have >30% relative cover and Populus fremontii is not present or, if present, then has <5% cover.
Rationale for Nominal Species or Physiognomic Features:
Classification Comments: For those stands without cottonwood.
Similar NVC Types:
Physiognomy and Structure: This seasonally flooded/saturated broad-leaved cold-deciduous forest forms a continuous tree canopy less than 15 m in height. Shrubs are sparse below the tree canopy, and the herbaceous layer is variable.
Floristics: These riparian woodland and forest stands are dominated by Salix gooddingii and/or Salix laevigata, either as single-species stands or as mixed stands. They generally are without Populus fremontii, but when present, it is not abundant. Other tree species present include Acer macrophyllum, Alnus rhombifolia, Alnus rubra, Celtis laevigata var. reticulata, Fraxinus velutina, Juglans microcarpa, Platanus racemosa, Populus balsamifera, Populus fremontii, Prosopis glandulosa, Quercus pungens, Salix hookeriana, Salix sitchensis, Sapindus saponaria var. drummondii, and/or Ungnadia speciosa. Shrubs may include Baccharis emoryi, Baccharis salicifolia, Cornus sericea, Rhus trilobata, Salix exigua, and/or Sambucus nigra ssp. caerulea (= Sambucus mexicana), as well as other riparian shrubs. The herbaceous layer is highly variable depending on season, length of time since last inundation, and degree of disturbance.
Dynamics: This alliance requires seasonal inundation or seasonal saturation. Stands occur on low-gradient streamside depositions and in floodplains which receive low-intensity flooding at least every few years.
Environmental Description: This alliance occurs on floodplains, streamsides, ditches, lake edges, and low-gradient deposits along rivers, that are seasonally flooded or seasonally have saturated soils. Stands occur from sea level to 2700 m elevation. Because of the climate throughout the range of this alliance, flooding can occur throughout the winter and spring. Annual rainfall totals are between 60 and 80 cm.
Geographic Range: This alliance ranges from California to New Mexico.
