Lumnitzera racemosa may also be found in association with the tidal creeks. The mid stratum consists of the scattered exotic shrub Parkinsonia aculeata. The ground stratum consists of a closed grassland/sedgeland with the grasses Leptochloa neesii, Panicum decompositum and Echinochloa colona and the Cyperus species. Excoecaria parvifolia low open forest may also occur as the only dominant over a grassland/sedgeland of Sporobolus virginicus and Cyperus procerus on the edges of tidal flats.
