- Abstract
Differences resulting from the passage of migrating dunes in coastal restinga vegetation in Ilha Grande, Piauí, Brazil were quantified, especially differential survival of tree species (wild Anacardium occidentale, cajuí; Byrsonima crassifolia, muricí) and successional floristic reestablishment. A phytosociological study totalling 108 quadrats (1.08 ha) and satellite images of the area from the past 16 years were used to examine the vegetation of the upwind tracks of two mobile dunes. Quadrats were arranged in four transects along the central and marginal residual ridges of each dune. Most species recorded were herbaceous. Satellite images suggest that plants along the central dune track are buried for approximately 14 years. Some evidence for progressive re‐establishment of woody species was found in the central dune track areas, but not in the marginal areas. No successional patterns were observed in the herbs and subshrubs. Most trees occur along the marginal (longitudinal) residual ridges. Anacardium occidentale and Byrsonima crassifolia predominated among tree species. Anacardium occidentale predominated in abundance, cover, frequency and basal area and survives partial burial when located at the dune track margins. The passage of migratory dunes is important for long term maintenance of the economically important cajuí and muricí populations of Ilha Grande.
