Species richness at HU sites was highest in hydric pine flatwoods, followed by cypress and graminoid
(grasses & sedges) plant communities, whereas saltwater marshes had the lowest richness (Table 2).

The trees are growing in a disturbed gravel substrate that is barren except for a few other early successional willow and graminoid

inflorescence and leaf lengths have tended to increase over the past decade at these study sites ([R.
Understory dominated by graminoid
herbs, with some Asteraceae, Polygalaceae, Scrophulariaceae, and terrestrial orchids (Bletia).
Three different graminoid
vegetation treatments will be planted on these plots initially for quantifying changes in credibility and geotechnical resistance to failure.
selaginoides was closely related to the tussock-forming graminoid
Schoenus ferrugineus growing on the top and sides of its tussocks.
At a regional level, there were 19 tree species, 11 shrub species, 57 latifoliated herbaceous species (H), 17 graminoid
herbaceous species (GH), 2 equisetoid herbaceous species (EH) and 17 vine-creeper species (C).
Schizachyrium scoparium is also the dominant graminoid
