Espinal Floodplain Forest Macrogroup

Description:
This macrogroup represents the riparian and edapho-hygrophilous forests that develop along the tributaries and main stem of the Parana and Uruguay river basins, in their mid to lower sections and down to the Parana river delta, which opens to the Rio de la Plata, in Argentina and Uruguay. The different vegetation types within the macrogroup vary depending on their location on the geomorphologies that result from past and current river dynamics, which influence the height, the age of the sediments on the riverbanks and drainage qualities of the soils. The vegetation seral stages and composition due to the hydrologic regimes closer to the river mouth include tidal movements, and the more-or-less saturated terrains left as a result of the meandering of the river. Based on these different settings the composition and structure of these forests range from tall, dense and stratified forests growing on old stable riverbanks with mature sediments, to almost monodominant stands of lower stature in more recent and dynamic settings. For the mature forests, periodically inundated for a short period of time, the characteristic tree species are <i>Acacia bonariensis, Allophylus edulis, Blepharocalyx salicifolius (= Blepharocalyx tweediei), Chrysophyllum marginatum, Cupania vernalis, Eugenia uniflora, Fagara hyemalis, Holocalyx balansae, Inga vera ssp. affinis, Lithraea molleoides, Luehea divaricata, Myrcia selloi, Myrcianthes cisplatensis, Myrcianthes pungens, Myrsine parvula, Nectandra megapotamica, Ocotea diospyrifolia, Sapium haematospermum, Scutia buxifolia, Sebastiana brasiliensis, Syagrus romanzoffiana, Tabernaemontana catharinensis, Erythrina crista-galli, Myrceugenia glaucescens, Myrsine laetevirens, Nectandra angustifolia (= Nectandra falcifolia), Ocotea acutifolia</i>, and <i>Terminalia australis</i>. In the case of floristically poor riverine forests, the dominants are <i>Albizia inundata</i> and <i>Sapium haematospermum</i>.
