Name: Carex subspathacea - Dupontia fisheri Salt Marsh Group
Reference: NatureServe Biotics 2019
Description: This group is defined as sparse to closed assemblages of forbs and graminoids that are highly adapted to saturation and saline conditions that occupy the intertidal zone of the Bering Sea and Arctic Ocean coastlines. Characteristic species include the halophytic graminoids <i>Puccinellia phryganodes, Carex subspathacea</i>, and <i>Dupontia fisheri</i> and the succulent forbs <i>Stellaria humifusa</i> and <i>Cochlearia groenlandica</i>. Arctic salt marshes develop in protected coastal areas where relatively flat land receives periodic input of tidal waters. Depending on local topography and exposure, marshes may be small patch to matrix-forming. Dynamics are chiefly driven by the inundation of tidal waters, which erode and redeposit salt marsh sediment. The severity and magnitude of these effects are compounded by storm events, ice rafting and thermal degradation of ice-rich coastal permafrost (where present).
