Tidal Marshes

1) Inundated by twice daily tides to monthly lunar tides.

2) Exposed to varying salt concentrations in water column (0 to 35ppt).

3) Few vascular plant able to tolerate these stresses!

The Cordgrasses (Spartina)

1) Smooth Cordgrass (Spartina alternifolia).

2) Saltmeadow Hay (Spartina patens).

3) Tall Cordgrass (Spartina cynosuroides).

Page 3: Wetland Creation and Restoration in Virginia: an Overview
Page 4: Wetland Creation and Restoration in Virginia: an Overview

Smooth Cordgrass (Spartina alternifolia)

- aka Salt Cordgrass - high salinity tolerance (5 to 40psu)

- high inundation tolerance (semi-diurnal inundation)

- long lived perennial w/ rhizomatous root system
