Name: Amazonian-Guianan White Sand Flooded Savanna & Shrubland Macrogroup Reference: NatureServe Biotics 2019 Description: This macrogroup includes a few different types of savannas scattered in the ecotone area between the Amazon rainforest and the Guiana Shield piedmont. In the western area of this ecotone, in Colombia, Brazil and Venezuela, it is represented by mosaics of grassland and open shrubland or short-statured woodland, in the upper basins of blackwater tributaries of the Amazon and Orinoco rivers, with deep quartzitic white sand, oligotrophic and acidic soils. The different types of vegetation organize in a system of mounts and swales with the woody vegetation occupying the higher topographies and inundated herbaceous vegetation in the depressions. Characteristic species are <i>Heteropterys oblongifolia, Emmotum glabrum, Ormosia macrophylla, Calliandra tsugoides, Pagamea guianensis, Tepuianthus savannensis, Schoenocephalium cucullatum, Schoenocephalium teretifolium, Schoenocephalium martianum, Guacamaya superba, Xyris</i> spp., <i>Rhynchospora</i> spp., and <i>Paepalanthus</i> sp. Towards the east of its distribution, the macrogroup includes the flooding savannas of the Rupununi Rio Branco complex, characterized by lateritic poor soils, seasonally inundated and poorly drained. These are open savannas without woody vegetation, with species such as <i>Fimbristylis ferruginea</i> and <i>Rhynchospora barbata</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:40957-{FEC3A36E-DF53-4FB3-A889-191093B72AB8} Plot-observations of this Community Concept: 0
