marshmargin
Marshmargin is a term used in wetland ecology to denote the outer edge or transition zone of a marsh. It lies at the interface between the marsh interior, with saturated soils and standing water, and adjacent upland or open water habitats. The marshmargin experiences variable hydrology and salinity and supports a distinct plant and animal community compared with the inner marsh.
Definition and scope: The exact delineation can vary; it may refer to the landward edge where emergent
Ecology: Plant communities at marsh margins are typically tolerant of periodic inundation and may include species
Dynamics and threats: Marsh margins can migrate inland or seaward in response to sedimentation, sea-level rise,
Management and restoration: Restoration aims to reestablish natural hydrological regimes, replant edge vegetation, and remove barriers
