Name: North American Atlantic & Gulf Coastal Salt Marsh Macrogroup
Reference: NatureServe Biotics 2019
Description: This macrogroup encompasses eastern North American tidal marshes along the Atlantic and Gulf coasts, ranging in halinity from salt to brackish, and in tidal regime from regularly twice-daily flooding on low marshes to irregularly flooded high marshes, as well as hypersaline pannes. It also includes saline inland prairie. <i>Distichlis spicata, Spartina alterniflora, Spartina patens</i>, and species of <i>Salicornia</i> and <i>Sarcocornia</i> are characteristic throughout the range. These species are present but less abundant in brackish marshes that occur along tidal rivershores or in other settings receiving freshwater mixing. Here, additional species include <i>Spartina cynosuroides, Schoenoplectus americanus, Typha angustifolia</i>, and others. Associated species vary across the north-to-south expanse of this macrogroup. Towards the north, common associates include <i>Juncus gerardii, Limonium carolinianum, Plantago maritima var. juncoides</i>, and <i>Triglochin maritima</i>. From the Chesapeake and mid-Atlantic south, <i>Batis maritima, Juncus roemerianus, Monanthochloe littoralis, Sesuvium portulacastrum, Spartina spartinae</i>, and <i>Typha domingensis</i> become increasingly common associates. Salt marshes and pannes are regularly to irregularly flooded by shallow polyhaline waters as a result of lunar, wind and storm tides. Brackish tidal marshes develop along estuaries where freshwater mixes with ocean saltwater moving up the estuary from the tidal force. Waters in brackish marshes are generally in the salinity range of 0.5-18 ppt, and the vegetation is subject to flooding from the twice-daily tides. This macrogroup ranges along the Atlantic Coast and Gulf of Mexico region from the New England states and the southern Maritime Provinces of Canada south to northern Mexico.
