Ecological restoration is an important tool to reverse habitat loss and recover ecosystem services. Here, for two years, we examine the dynamic of Posidonia oceanica following the restoration of a 1149 m meadow damaged by the Concordia shipwreck. To evaluate the suitability of a recently employed seagrass restoration protocol, we assessed the patches' survival and development by high-spatial resolution photomosaics over the whole transplanted surface. To estimate recovery trajectories, we quantified the cuttings' survival, shoot density, and Daily Leaf Production within fixed monitoring squares. The outcomes confirmed that our protocol could be efficiently applied at larger scales, showing diminutions in cuttings' survival and shoot density over the first year (up to -20%), followed by stability in the number of living cuttings and increases of leaf bundles (up to +5%/year). Our insights demonstrate that the recovery of P. oceanica can be speeded up and underline the need for case-specific transplantation strategies.
生态恢复是逆转生境丧失和恢复生态系统服务的重要手段。在这里，我们研究了在科伦坡号沉船破坏的 1149 米草地进行修复后的两年间海洋羽藻的动态。为了评估最近采用的海草恢复方案的适宜性，我们通过对整个移植表面的高空间分辨率照片镶嵌图来评估斑块的存活和发展情况。为了估计恢复轨迹，我们在固定监测方块内量化了插条的存活率、芽密度和每日叶产量。结果证实，我们的方案可以在更大的范围内有效地应用，显示出插条存活率和芽密度在第一年（高达-20%）下降，随后活插条的数量和叶片束的增加（高达+5%/年）趋于稳定。我们的研究结果表明，海洋羽藻的恢复可以加快，并强调需要针对具体情况的移植策略。
