Because this graph shows a range of salinity tolerances, salinities at the higher ends of those bars will produce lethal environments at extended periods.

The eastern stretches of that marsh are probably more dominated by bulrushes, cattails, and Sagitarria species, which are on the lower end of salinity tolerances.
Thanks for posting the pdf. Great stuff.

What do you have against bulushes and cattails? I know they are not great duck habitat, but they are hardy, they will slow a tidal surge, and are fairly good at holding the ground underneath them from washing away.

What am I missing? It it just a personal thing, or are they actually bad from the point of view of preserving the marsh?
