Distichlis spicata - (Scirpus nevadensis) Herbaceous Vegetation
Translated Name: Saltgrass - (Nevada Bulrush) Herbaceous Vegetation
Unique Identifier: CEGL001773
Classification Approach: International Vegetation Classification (IVC)
Summary: This herbaceous association occurs in Oregon, Idaho, Colorado and Wyoming and may extend into California, Nevada and Washington. This description is based on information only from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This graminoid association is found in playas and sandsheets at 2295 to 2320 m elevation. Stands are intermittently flooded and may have poorly or well-drained loamy sand or sandy clay soils. Ground cover is primarily bare soil with 70-91% cover. This association may be found as a distinct band around frequently flooded areas, or as continuous cover in shrubland openings with salty, frequently inundated soils. Vegetation cover is generally sparse (<10%) but can be dense in places. Scirpus nevadensis is dominant in wetter areas and may have up to 90% cover. Distichlis spicata is present with <5% cover. The few other species present represent typical regional salty soil species such as Cleome multicaulis, Suaeda calceoliformis, Spartina gracilis, Triglochin maritima, and scattered individuals of Sarcobatus vermiculatus.
