Riverine Sand Beaches
Riverine sand beaches occur largely in whitewater Amazonian rivers, which are subject to changes in water levels of up to 7 meter between the wet and dry seasons. During the dry season, extensive sandbars are exposed along the rivers and remain dry until the onset of the next wet season. Sandy beaches constitute nesting and also foraging habitat for a set of resident and migratory birds, some of which nest exclusively on this habitat type. Riverine sand beaches can be the first stage of a river island before grasses and Tessaria sp. begin the process of colonization and vegetative successions.
