Alagna et al. (2019) suggest new transplantation methods for Posidonia oceanica (Linnaeus) Delile, inspired by its natural recovery process after disturbance due to dredging operations for gas-pipelines. They observe that P. oceanica vegetative fragments naturally settled only on loose calcareous stones deployed to fill the trenches of the gas-pipeline. No recovery was noted on dead matte, sand and large calcarenitic boulders. Following a new pilot restoration project currently ongoing in the same area, we demonstrate that natural recovery also occurs on dead matte. After examining other alternative transplantation methods for P. oceanica, the Authors suggest using their "habitat enhancement units" method for the restoration of seagrasses, not only on rocky bottom but also on sand and other bare substrate requiring general environmental restoration. Here we express disagreement on certain issues reported in the paper.
阿加尼亚等人（2019 年）提出了波西多尼亚海草（Linnaeus）Delile 的新移植方法，灵感来自于其在疏浚天然气管道时受到干扰后的自然恢复过程。他们观察到，波西多尼亚海草的营养繁殖体仅自然沉降在疏松的钙质石块上，这些石块是用来填充天然气管道的沟渠的。在死亡的软泥、沙子和大型钙质巨石上没有发现恢复的迹象。在同一地区目前正在进行的一个新的试点恢复项目之后，我们证明了在死亡的软泥上也会发生自然恢复。在研究了波西多尼亚海草的其他替代移植方法后，作者建议使用他们的“栖息地增强单元”方法来恢复海草，不仅在岩石底部，而且在需要一般环境恢复的沙子和其他裸露基质上。在这里，我们对该论文中报告的某些问题表示不同意。
