• Abstract:
  Spatiotemporal analysis of Lake Surprise and SL-15 (15th spoil island in St. Lucie County) has allowed for a robust assessment of successful Florida Department of Transportation (FDOT) activities. Project results showed that bridge construction in Lake Surprise did not cause negative impacts to seagrass. In fact, it is arguable that the bridge has improved conditions in the lake. Seagrass is expected to continue expanding and becoming more dense. At SL-15, it is clear that natural recruitment will produce excellent densities and heights in target mangrove species. Initial planting is most likely unnecessary if the design can amplify natural recruitment. Seagrass recruitment, however, may not occur as easily. Improving exchange and possibly shifting resources towards seagrass transplanting should improve success provided soils are analyzed to ensure ample soil phosphorus is available to transplants and recruits. Larger or wider flushing channels would most likely preserve tidal exchange and improve recruitment of seagrass.
