. Dune building and stabilization with vegetation. Sand dunes; Grasses; Shore protection. per hectare divided into two or three applications beginning in early spring should be used for a year or two. This should be reduced to a single application in early spring at intervals of 1 to several years as soon as growth permits. Vigor is usually maintained after sand supply is reduced or cut off entirely with a single application of 30 kilograms of nitrogen per hectare applied at 1- to 2-year intervals. Management requirements for sea oats are very similar to those for bitter panicum. Protection from foot and vehicular traffic is very important and storm- or man-induced breaks must be repaired. Sea oats stems with seed heads need special protection from harvest in many areas due to the growing demand for them for ornamental purposes. This can have a significant effect on future dune development and stability by depleting the seed supply and consequently the potential for natural spread and replacement of vegetation. Harvesting of seed stalks does not harm the live plants as the flowering stems die and are replaced by new tillers from the basal nodes. Sea oats seeds represent the major natural vegetative repair mechanism in the foredune area in this region. (c) Other Species. There are a number of other pioneer zone plants that commonly occur along the gulf coast and contribute to dune building and stabilization but are not ordinarily planted for this purpose. Railroad vine {Ipomoea pes-cappae) is one of the more prominent plants. This is a robust vine that is capable of rapidly spreading over foredunes and back beach (Fig. 30). It is not planted because it is less effective in trapping sand than the dune grasses. There are also other smaller Ipomoea Figure 30. Railroad vine, 82.
