Reference: EcoArt 2002
Description: This semipermanently flooded alliance has been described from high-elevation intermountain parks in Colorado. Stands occur in lowland habitats such as saline marshes, salt flats, and at calcareous springs in extreme rich fens. These habitats are flooded throughout the growing season in most years. The water table may drop below the surface at the end of the growing season or during drought years, but the soils will still be saturated which permits the development of organic peat. Soils are poorly drained, deep, saline and alkaline, often derived from calcareous marls or limestone. Vegetation included in this alliance is characterized by an herbaceous layer that is dominated by the perennial rhizomatous forb ~Triglochin maritima$. Other common species include ~Carex microglochin, Eleocharis quinqueflora, Puccinellia nuttalliana, Salicornia rubra, Ranunculus cymbalaria, Schoenoplectus americanus (= Scirpus americanus)$, and ~Symphyotrichum ciliatum (= Aster brachyactis)$. Cover and species composition is controlled largely by salinity, which is regulated by the amount of water dilution. ~Triglochin maritima$ and ~Salicornia rubra$ were more abundant in saline areas, and the salt-tolerant ~Distichlis spicata$ was restricted to the more saline sites. Generally, vegetation height, cover, and species diversity tend to vary inversely with salinity. Diagnostic of the wetland herbaceous alliance is the dominance of ~Triglochin maritima$.
