“…As on Moçambique beach, a reduction in species diversity occurred in areas with more wind-blown sand. Travis (1977) also found that the beach orientation relative to the prevailing winds and resultant aeolian sand deposition was responsible for the differential growth of Uniola paniculata in two beaches on Hatteras Island. On the coastal dunes of South Africa, particularly in Natal, Donnelly and Pammenter (1983) affirm that salt spray and sand deposition are key factors in controlling the zonation and distribution of the vegetation.…”

“…Foredune vegetation can be directly affected by environmental factors such as beach/surfzone type, salt spray, low nutrient conditions, sand burial by aeolian deposition, surface erosion (Oosting and Billings, 1942;Barbour and de Jong, 1977;Travis, 1977;Barbour, 1978;Boorman, 1982;Avis and Lubke, 1985;Hesp, 1988Hesp, , 1989Maun, 1994;Hesp and Martinez, 2007), sand movement (Moreno-Casasola and Epejel, 1986), high surface temperatures and low water retention in a high porosity substrate (Van der Valk, 1974;Cordazzo and Seeliger, 1995;Hesp, 1991).…”

This paper examines patterns of foredune vegetation along an embayment in southern Brazil and the relationships between variations in percent cover and diversity, and environmental factors such as beach/surfzone type and exposure to wind and wave energy. The study was conducted on Moçambique Beach, Brazil, which displays significant alongshore variations in exposure to the prevailing winds and waves, beach/surfzone morphodynamic type, type and dimensions of the dune systems and foredune vegetation cover and diversity. Two vegetation surveys were carried out in contiguous 1 m 2 quadrats across the foredune. The presence/absence, percent cover of the species, diversity and similarity between the vegetation of the profiles surveyed and their relation with environmental conditions are examined. The results show that the vegetation cover decreases from south to north, possibly reflecting the increasing exposure to wind and wave energy. Distinct patterns of species distributions occur along Moçambique beach, such that different plant species are dominant on the southern, middle and northern ends of the beach. A cluster analysis demonstrated two associations: the first one is represented by the profiles located in the lower energy zone of the beach, and the second association is represented by the profiles more exposed to wind and wave energy, sediment deposition and salt spray. The diversity of species decreases northwards, possibly influenced by the surfzone type, number of breaking waves and degree of aeolian transport. The presence/absence of the species and the vegetation cover on the foredune reflect the varying levels of exposure of the beach and foredune to the winds and waves and also reflect the volume of sediment deposition on the foredune and the beach mobility determined by the morphodynamic beach/surfzone type.

“…Previous work on the growth and development of A. breviligulata includes Laing (1958Laing ( , 1967, Olson (1958), van der Valk (1974Valk ( , 1977, Travis (1977), Krajynik & Maun (1981, 1982, and Eldred & Maun (1982). The similarity between A. arenaria (L.) Link and A. breviligulata has led most authors to believe that the conclusions attributed to the more commonly studied A. arenaria could be applied to A. breviligulata (Marshall 1965;Travis 1977;Huiskes 1979).…”

“…Stalter (1971) reported sea oats plants buried 2.13 m in accreting dunes in South Carolina. Accreting sand leading to partial burial appears to account for increased aerial growth and rhizome expansion (Dahl et al, 1974;Travis, 1977).…”
