Experiments at the shore and in the nursery were conducted to develop an accelerated and more effective revegetation program on beach and dune areas. Four grasses show promise American beachgrass, sea oats, dune panic grass, and saltmeadow cordgrass. Randomized blocks of plantings, with at least three replications, were used in the experiments. Comparison of various methods of producing nursery stock, transplanting at the shore, and fertilization produced positive results shown in figures, tables and photographs. The most practical and economical methods for each step of the program are suggested. American Beachgrass is best planted between 1 November and 1 April. Plants, of 3 to 5 stems, dipped in a clay slurry, are spaced 18 inches by 18 inches by a machine planter. Depth of planting is 6 to 8 inches. Such a planting, properly fertilized, was used in dune growing. Fifteen months after planting, a strip 100 feet wide had accumulated 16 cubic yards of sand per running foot of beach. Experiments are being continued.
