Environmental Impact Research Program. A Low-Cost Transplanting Technique for Shoalgrass (Halodule wrightii) and Manatee Grass (Syringodium filiforme).

摘要

A simplified, low-cost transplanting technique has been developed for seagrasses, Halodule wrightii and Syringodium filiforme, for use in high- and low-current regimes. The method makes use of mature, vegetative shoots, free of sediment and anchored to the substrate. The technique accounts for selection of planting stock, species growth rate, and depth of planting site for estimating the design, labor, and material requirements of a transplant. Examples are provided to illustrate use of the tables and formulas for computing the necessary requirements. A cooperative research program has developed low-cost transplanting techniques for the subtropical seagrass species shoalgrass (Halodule wrightii) and manatee grass (Syringodium filiforme). The transplanting techniques presented are effective for: restoring areas damaged by coastal engineering activities, habitat enhancement and sediment stabilization. The technique involves planting a relatively sparse array of sprig bundles over a barren area. Lateral rhizome growth from these bundles results in creation of a characteristic meadow. This technique is estimated to result in substantial labor reductions compared to plug or fiber-mesh methods recommended in a previous report by Phillips (1980).
