Name:
Orinoquian Floodplain Peat Meadow & Marsh Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroups represents the different wetlands associated with the Orinoco River floodplain and delta, in conditions that accumulate peat in the soils. Inland it includes the <i>Mauritia</i> palm swamps on saturated peat soils developed on a sandy horizon which in turn develops on less permeable soil. These palm swamps are related to the hydrologic regime of the river, feed mostly with blackwaters, and are almost permanently waterlogged. They grow in a mosaic with inundated savannas and herbaceous swamps. Species typical of these palm swamps are <i>Mauritia flexuosa, Ludwigia lithospermifolia, Ludwigia nervosa, Xilopia aromatica, Cecropia palmatisecta, Cuphea odonnelli, Desmocellis villosa, Mayaca sellowiana, Xyris caroliniana, Rhynchospora tenuis, Hypogynium virgatum, Calophyllum lucidum</i>, and <i>Philodendron acutatum</i>. The macrogroup also includes the marshy meadows of the lower Orinoco delta dominated by <i>Montrichardia arborescens, Thalia geniculata, Typha domingensis, Cyperus giganteus, Heliconia psittacorum, Costus arbicus, Renealmia alpinia, Eichhornia crassipes, Paspalum fasciculatum, Blechnum serrulatum, Acrostichum aureum</i>, and <i>Cyperus articulatus</i>. This system with a similar composition continues south along the coast of Guyana and Suriname, in brackish but mainly freshwater wetlands of the coastal plain.
