CEGL000943 Populus fremontii / Salix geyeriana Riparian Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Fremont Cottonwood / Geyer''s Willow Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This Great Basin riparian cottonwood woodland association is reported in west-central Nevada. Sites are generally above 1665 m (5460 feet) elevation and typically on northeast aspects. Stands occur as inclusions in other riparian vegetation mostly on small streams. Substrate is coarse-textured loam. Ground cover is a mixture of litter (41%), bare ground (13%), vegetation (11%), pavement (11%), and rock (24%). The vegetation is characterized an open tree canopy dominated by Populus fremontii with Pinus monophylla and Juniperus osteosperma trees often present. The moderately dense to dense shrub layer is dominated by Salix geyeriana. Occasional Artemisia tridentata may be present. The herbaceous layer of sampled stands was dominated by the exotic annual grass Bromus tectorum. Diagnostic of this Fremont cottonwood association is a shrub layer dominated by Geyer''s willow.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is known from 4 plots in drainages in Churchhill Canyon in northeastern side of Pine Mountains in the eastern Great Basin. Plots appear to be disturbed by the dominance of Bromus tectorum in the herbaceous layer. More survey work is needed to find and classify less disturbed riparian forests to further clarify the composition and structure of this association.
