The estimated mean elevations (95% confidence interval) were well separated for the nine vegetation communities on the Cape Canaveral Barrier Island Complex, FL.

The parameter estimate are from a generalized least square model of elevations for each community with spatial correlation structure. Stratum SD is the modeled standard deviation which was allowed to vary by community. The model also allowed the errors to be spatially correlated according to an exponential function with coefficients fit to the data.
