Vereda is a phytophisiognomy with emergent Buriti palm (Mauritia flexuosa), surrounded by groups shrubby-herbaceous species somehow dense. The Veredas are surrounded by Campo Limpo (clean field) usually wet, and the Buriti trees do not form a canopy, as happens on a Buriti field. On Veredas the Buritis feature an average height of 12 to 15 meters and the cover varies between 5% to 10%. Veredas are found on hydromorphic soil almost all year round. Usually they occupy valleys or plain areas following drainage lines poorly defined, normally with no murundus. They are also usual on intermediate position of the land, close to springs (place where water wells up from an underground), or on the border of Mata de Galeria (Gallery Forest). The occurrence of Veredas are conditioned to the upwelling water table (phreatic), resulting from layers of different permeability on sedimentary areas of the Cretaceous and Triassic (RIBEIRO & WALTER, 1988). The Veredas play a key role on the maintenance of Cerrado fauna, since they serve as landing place for the avifauna, refuge, shelter, food source and reproduction place for the terrestrial and aquatic fauna as well.
