Southwestern Amazon Floodplain Forest Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup includes seasonal varzea forest and igapo forest of the whitewater and black- and clearwater rivers of the southwestern Amazon in Bolivia, Peru and in Brazil in the upper and mid basins of the Purus and Madeira rivers. Whitewater flooding forests (varzea) vary depending on their location and flooding levels, with higher banks flooded only sporadically and lower banks and floodplains inundated seasonally up to 1 m for 3-4 months a year. Forests are 25-30 m tall and have an irregular canopy and several strata. Diagnostic species are <i>Manilkara bidentata ssp. surinamensis (= Manilkara surinamensis), Calycophyllum spruceanum, Hura crepitans, Gustavia augusta, Gustavia hexapetala, Dypterix micrantha, Xylopia ligustrifolia, Clarisia biflora, Pouteria bangii, Ceiba pentandra, Apeiba tibourbou, Astrocaryum murumuru, Chelyocarpus chucco, Bactris concinna, Terminalia amazonia, Cavanillesia hylogeiton, Swietenia macrophylla, Theobroma speciosum, Couroupita guinanensis, Virola surinamensis, Ficus insipida, Ficus trigona, Diospyros ebenacea, Heliconia marginata, Heliconia episcopalis, Duguetia quitarensis</i>, and <i>Salacia elliptica</i>. Blackwater flooding forests (igapó) represent a complex of forest types, including riparian and those of depressions and surrounding lagoons, all of them inundated seasonally with flowing water which is poor in sediments but high in humic acid contents. Diagnostic communities are formed by <i>Macrolobium acaciifolium, Macrolobium suaveolens, Campsiandra laurifolia, Maquira coriacea, Couratari tenuicarpa, Virola sebifera, Eschweilera albiflora, Eschweilera coriacea, Eschweilera turbinata, Eschweilera parvifolia, Symmeria paniculata, Sclerolobium guianense, Mabea occidentalis, ordia nodosa, Astrocaryum jauari, Bactris riparia, Bactris simplicifrons, Hevea brasiliensis, Genipa spruceana</i>, among others.
