Abstract
Observations of experimental dunes made over a period of nine years indicate differences in utilizing three different dune species along the North Carolina coast and in the type of dunes produced by them.Ammophila is superior in ease of establishment and rate of sand accumulation but is shortlived. It produces a gently sloping dune.Uniola is difficult to propagate but is an excellent dune builder and eventually dominates the foredune. Grown alone, it produces a steep dune front.Panicum is an excellent companion plant to bothAmmophila andUniola. It is easy to propagate, relatively free of pests and produces dunes intermediate in shape, betweenAmmophila andUniola. Plantings of mixtures of two or more of these species should greatly improve long-term dune stability compared with either planted alone.
