Physical stresses and vegetation cover in different zones at the salt marsh and estuarine sites.

Data are means ± 1SE. Sample sizes are 8 for salinity, moisture, and 15 for vegetation cover. Flooding frequency (shown as a range) was estimated based on previous studies and field observations.
Statistical analyses were conducted using generalized linear models. Gamma regressions with log link were used for salinity and moisture while a Poisson regression with log link was used for vegetation cover. -, no data. Flooding indicates the percentage of days flooded in a year.
