Name: Arctic Tidal Salt Marsh Macrogroup
Reference: NatureServe Biotics 2019
Description: This macrogroup consists of herbaceous tidal salt marshes with &gt;10% vascular species cover that are subject to regular inundation. This includes low marshes, brackish meadows, and high marshes. Common herbaceous species in the mid to lower salt marsh include <i>Carex glareosa, Carex ramenskii, Carex subspathacea, Carex ursina, Cochlearia officinalis, Dupontia fisheri, Puccinellia phryganodes</i>, and <i>Stellaria humifusa</i>. In brackish meadows inland of the mid to lower salt marsh additional species such as <i>Calamagrostis deschampsioides, Chrysanthemum arcticum</i>, and <i>Salix ovalifolia</i> commonly occur. Tidal salt marshes are associated with estuaries or coastal lagoons or other locations protected from wave action, such as the inland side of barrier islands. In the Arctic, salt marshes may occur wherever there is relatively flat land at sea level that is subjected to permafrost subsidence or storm surge inundation. They occur along Alaska's Arctic coastline from the Bering Sea to the Arctic Ocean. The Bristol Bay lowlands in southwestern Alaska mark a major transition zone between Arctic and more temperate Pacific tidal marshes. Species common to the Pacific Coast salt marshes dominate east of the Alaska Peninsula, while species common to the Arctic salt marshes become more dominant to the west of the Alaska Peninsula and Bristol Bay.
