Name:
Central Amazon Floodplain Forest Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup includes seasonal varzea forest and igapó forest of the whitewater and black- and clearwater rivers of the mid and lower Amazon Basin in Brazil. The lower whitewater floodplains are subjected to flooding of up to seven months a year, and the varzea forest can extend for kilometers away from the river if the topography is flat enough, though farther from the main stream the flooding season is shorter. Among the diagnostic tree species are <i>Pyranhea trifoliata, Vitex cymosa, Tabebuia barbata, Nectandra amazonum, Crescentia amazonica, Casearia aculeata, Ceiba pentandra, Manilkara amazonica, Pterocarpus amazonum</i>, and <i>Tapirira amazonica</i>. The igapo communities vary depending on the substrate and length of the flooding. Communities on white sands flooded for 6-7 months have a simple structure, with a 10-m tall, open canopy of scattered shrubs and few tree species. Those with a shorter flooding period and richer soils are more diverse and include <i>Myrciaria dubia, Dalbergia inundata, Borreria capitata, Eugenia chrysobalanoides, Eugenia cachoeirensis, Remijia tenuifolia, Couepia paraensis, Leopoldinia pulchra, Licania apetala, Licania heteromorpha, Eschweilera tenuifolia, Alchornea schomburgkii, Mabea nitida, Maprounea guianensis, Parkia discolor, Swartzia polyphylla, Swartzia argentea, Astrocaryum jauari</i>, among other species.
