多塞特海域生态泊位显著修复海草草甸

英国多塞特斯图德兰湾通过采用生态泊位系统，实现了濒危海草栖息地的快速恢复。1这一新型泊位装置由2米螺旋螺钉和2米弹性上升管组成，能够随潮汐涨落伸缩，用弹性系绳替代传统锚链，从而防止海床和海草遭受破坏。1

2021年安装的10个试验性生态泊位所在区域取得显著成效，海草裸露面积在2021至2025年间平均缩小94%。1相比之下，保留传统链式泊位至2023年的第二研究区域，海草疤痕缩小幅度为65%。1研究员基拉·邓恩表示："结果清楚地表明，当物理干扰被移除时，海草在区域内恢复。看到这个重要栖息地恢复速度如此之快令人难以置信地鼓舞人心。"1

斯图德兰湾2019年被指定为海洋保护区，拥有英国最大的海草草甸之一。1

Traditional anchors have long scarred seagrass beds in England's Studland Bay, but a shift toward ecological moorings is reversing the damage at an impressive pace. The innovative system replaces conventional anchor chains with elastic risers that move with tidal flows, preventing the seafloor from being churned and eroded.1

Researchers have documented striking recovery in areas equipped with these new moorings. Ten experimental ecological moorings installed in 2021 saw an average 94% reduction in exposed seagrass between 2021 and 2025, while a second study area that retained traditional chain moorings until 2023 showed a 65% decrease in scarring.1 Kira Dunn, a researcher involved in the work, emphasized the significance of these findings: "The results clearly show that when physical disturbance is removed, seagrass recovers within the area. It is incredibly encouraging to see this important habitat recovering at such a rapid rate."1

The ecological moorings function through a two-meter spiral screw anchored to the seafloor, connected to a two-meter elastic riser that flexes with changing tides.1 Studland Bay has been designated a marine protected area since 2019 and contains one of the United Kingdom's largest seagrass meadows.1 These findings provide scientific evidence that could guide seagrass conservation and restoration efforts across other busy waterways in Britain.
