A vegetation transect of 78 km was studied among 4 vegetation types : Restinga (coastal vegetation), Cerrado (woody savanna), Cerradão (dense woody savanna), and Forest, as well as three forested sites around Lagoa do Caçó, located approximately 10
km of the transect. Soil profiles in this transect were sampled for δ13 C analysis, as well as buried charcoal fragments were used for 14 C dating. The vegetation dynamic inferred in this study for northeastern Brazil is in agreement with the results
