CEGL001168 Forestiera pubescens Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Stretchberry Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association is reported from canyon bottoms, floodplains, sandy terraces along major rivers, and washes in southwestern Colorado, northeastern Arizona, southeastern Utah, southern Nevada and southern California. Elevation ranges from 1340 to 1680 m (4400-5500 feet). Stands typically form a narrow, but continuous, band about 3 m above the channel on streambanks and natural levees at the interface between the riparian zone and drier uplands. They occur on the outer edge of the active floodplain. Soils range from silty clays over clay loam to sandy loam derived from alluvium. This shrubland consists of a dense to open canopy of Forestiera pubescens, often with Atriplex canescens, Ericameria nauseosa, or Rhus trilobata, on the flat benches and floodplains adjacent to and above the river channel. There is often a mix of riparian and upland vegetation in these areas, with Salix exigua forming a dense band along the stream edge. This dense riparian shrubland can form a narrow, unfragmented, continuous cover that may alternate creekside to creekside, as part of the natural mosaic of the floodplain for one-tenth of a mile to several miles. Phragmites australis, a tall erect grass, or Sporobolus airoides often occur among the shrubs, with Artemisia tridentata, Ericameria nauseosa, or pinyon-juniper dominating the adjacent upland vegetation. The dominance or codominance Forestiera pubescens in the shrub layer characterizes this association.

Classification Comments: This association includes California stands reported in Forestiera pubescens Shrubland Alliance (Sawyer et al 2009) from southeastern Great Basin and Mojave Desert (Keeler-Wolf and Thomas 2000) to southern California mountains (Klein and Evens 2005), and Sierra Nevada and Coast Ranges (Twisselman 1967) (J. Evens pers. comm. 2017). Scattered outlier populations of Forestiera pubescens occur in the Great Valley of California that also need to be surveyed. More survey and classification work are needed to clarify the concept of this association throughout its range. It may be possible to split it into more associations based on understory dominants. Forestiera pubescens also occurs in Big Bend, Texas, and Oklahoma, so stands may also be present there, too.

Floristics: This shrubland consists of a dense to open canopy of Forestiera pubescens, often with Atriplex canescens, Ericameria nauseosa, or Rhus trilobata, on the flat benches and floodplains adjacent to and above the river channel. There is often a mix of riparian and upland vegetation in these areas, with Salix exigua mixing or forming a dense band along the stream edge. This dense riparian shrubland can form a narrow, unfragmented, continuous cover that may alternate creekside to creekside, as part of the natural mosaic of the floodplain for one-tenth of a mile to several miles. Phragmites australis, a tall erect grass, or Sporobolus airoides often occur among the shrubs. Common forbs include Descurainia pinnata, Chenopodium album, and Stanleya pinnata. The invasive, exotic shrub Tamarix chinensis may be present to codominant in some stands. Artemisia tridentata, Ericameria nauseosa, or pinyon-juniper often dominate the adjacent upland vegetation. This appears to be a flood-tolerant association which may be excluded from grazing due to the density of shrub cover.

Concept Lineage: KAS 1-17: CEGL002959 was created based on reports from Keeler-Wolf and Thomas (2000) and was archived based on communications with Julie Evens (pers. comm. 2017). She thinks her stands in the Mojave Preserve and Death Valley NP are outliers of CEGL001168 and should be included in it.
