Did you know?
Salt shrub is perhaps one of the best communities to see the interaction of the landscape and tidal range. Large areas of salt shrub can be found where there are broad, gentle slopes intersecting the upper range of spring and storm tides. Where slopes of the marsh basin are steep and the intersection with the tidal range is narrow, salt shrub is condensed into a thin band (MacDonald and Edinger 2000).

State Ranking Justification [-]
There are estimated to be between 20 and 50 occurrences statewide. The very few documented occurrences have good viability and are protected on public land. The community is restricted to sheltered areas of the seacoast in the Coastal Lowlands and Manhattan Hills ecozones. The current trend of the community is declining and the primary threat to this community is invasion by common reed (Phragmites australis). Secondary threats, common to all salt marsh complexes, include ditching and draining, dredging and filling, poor water quality, diking and impoundment, inlet stabilization, shoreline hardening, wrack accumulation, altered sediment budget, subsidence, changes in water circulation patterns, restricted tidal connection, and altered tidal hydrodynamics.
