Community stability would be increased where it can be successfully introduced. It can grow throughout the pioneer and most of the intermediate zones. Further research is needed for firm suggestions or recommendations. Three types of cuttings have been planted. Rooted stems taken from fore- dune plants have survived better than unrooted stems. Rooted cuttings in peat pots were more susceptible to wind erosion but those that survived grew faster than bare cutting. Woody stems were better transplants than soft (new growth) stems (Colosi, et al., in preparation, 1978). Seedlings only establish in areas of little sand movement and favor- able moisture. Transplanting is successful on sand flats with a high water table. Transplanting to high, dry sites is not recommended. Sea- shore elder does not invade established foredunes but continues to grow with them after earlier establishment at lower elevations. (h) Pennywort {Hydroaotyle sp.). This is a very effective sand-stabilizing broad-leaf plant. It is widely distributed throughout the region. It is tolerant of dune conditions, responsive to fertiliza- tion, and can be planted easily by sprigging. It is primarily a stabi- lizer rather than a builder because the round, fleshy leaves grow very close to the sand surface and provide only a few centimeters of trapping capacity at any one time. When only stabilization is needed, it can be sprigged in the same manner as Bermuda grass and fertilized like bitter panicum and sea oats. 77.
