Abstract: Transplants of shoal grass (Halodule wrightii) at Port St. Joe, Florida, indicate that it may be feasible to propagate seagrass on dredged material. Using the plug technique, two sizes of plugs were removed from a natural meadow and planted on coarse-grained dredged material at three different spacing intervals. Many of the transplants demonstrated a significant amount of growth before the project failed nearly 13 months after planting. Best growth was obtained with 375-cm² plugs planted on 0.9-m centers. The reason for the project failure is not known, but it is hypothesized that the factors involved included stresses from an unusually cold winter, exposure, erosion, sedimentation, variations in water quality, and heavy surf. While the study indicates that seagrass propagation on dredged material has promise, further field study is needed.
