Name: Spartina patens - Iva frutescens High Salt Marsh Group
Reference: NatureServe Biotics 2019
Description: This group encompasses vegetation in the regularly flooded, upper herbaceous or herb-shrub zones of salt marshes of the Atlantic Coast of temperate North America subject to polyhaline tidal waters. Dominance is most often by graminoids, with <i>Spartina patens</i> usually present and often dominant. Other characteristic species include <i>Distichlis spicata</i> and <i>Salicornia</i> spp. A fringe of shrub-herb vegetation, or sometimes more extensive areas of salt-tolerant shrubs, is common at the upper edges of the high marsh zone. High marsh vegetation generally develops between the levels of an area's mean daily high tides and spring tides. Wind tides may be important in marshes associated with barrier island systems. Associated species vary across the north-to-south expanse of this group. Towards the north, in the Gulf of Maine, common associates include <i>Juncus gerardii, Solidago sempervirens, Symphyotrichum novi-belgii</i>, and <i>Limonium carolinianum</i>; from the Chesapeake south, <i>Juncus roemerianus</i> is common and other associates such as <i>Baccharis halimifolia</i> are characteristic.
