A3851 Eleocharis obtusa - Eragrostis hypnoides Intertidal Mudflat Alliance
Type Concept Sentence: This is an herbaceous alliance dominated by graminoid species such as Eleocharis obtusa and Eragrostis hypnoides. The alliance is strictly herbaceous and dominated by low and prostrate graminoids, i.e., species that tolerate early-season flooding and summer drying that exposes mudflats with subirrigation. These occur on mudflats around wetlands that are seasonally flooded and subirrigated in the western U.S. These low-elevation (<1000 m [3280 feet]) marshes and mudflats occur along low-gradient streams, shallow ponds, and depressional wetlands. Soil is seasonally flooded to perennially saturated silt loam to clay.
