Figure G27. Scatterplot diagram for three-dimensional NMDS ordination of 129 tidal
herbaceous marsh plots, showing Axis 1 and 3. Plot membership in eight tidal herbaceous marsh
associations is based on cluster analysis. CEGL004187 = Tidal Oligohaline Marsh (Common
Reed Tidal Marsh); CEGL004195 = Tidal Oligohaline Marsh (Big Cordgrass Type);
CEGL004706 = Tidal Freshwater Marsh; CEGL006181 = Tidal Oligohaline Marsh (Mixed
Forbs Type); CEGL006418 = Tidal Mesohaline and Polyhaline Marsh (Transitional Marsh);
CEGL006578 = Tidal Oligohaline Marsh (Interior Depression Marsh); CEGL006586 = Tidal
Mesohaline and Polyhaline Marsh (Low Salt Marsh); CEGL006612 = Tidal Oligohaline Marsh
(Saltmeadow Cordgrass – Olney Three-Square Low Interior Marsh Type). Plots from the seven
Virginia national parks are labeled to the right of or below the symbol.
