Definission: Open shrubland and savanna in the north of Brazil and in Colombia and Venezuela, with low, sparse vegetation growing on sandy soils mostly within terra firme land in the Amazon. It can be of the ‘forested’ type, similar to a gallery forest, ‘wooded’ where the trees are shorter, and finally ‘grassy-woody’, where it occurs in wet plains near rivers and lakes. Amongst the more frequent plant families are the Arecaceae, Bromeliaceae, Clusiaceae, Humiriaceae, Marantaceae, Meliaceae and Rapateaceae.
Definission: Atlantic Coast Restingas, ecoregion. Vegetation complex ocurring in the seaside lowlands of Brazil, establishing over sea deposits of sandy sediment. It comprises open or scrubby profiles nearer the beaches, while inland it is forms tall forests.
Definission: Forest associated to intermittent water courses, which can be wide (riverine) or narrower and with the canopy meeting over the river (gallery)
Definission: Arenosols are sandy soils, including both soils developed in residual sands after in situ weathering of usually quartz-rich sediments or rock, and soils developed in recently deposited sands such as dunes in deserts and beach lands.
