Offshore marine renewable energy installations (MREI) introduce structure into the marine environment and can locally exclude destructive, bottom trawl fishing. These effects have the potential to aid restoration of degraded seabed habitats but may be constrained by timescales of ecological succession following MREI construction, and the removal of infrastructure during decommissioning. To inform managers about appropriate decommissioning strategies, a 25 km cable and associated rock armouring (Wave Hub, UK), installed on rocky reef, was monitored up to 5 years post-deployment. The epibenthic Assemblage composition, and Number of taxa remained significantly different from surrounding controls, while Abundance was similar in all survey years between the cable and controls. Six morphotaxa showed four patterns of colonization on cable plots compared to the controls: (i) Early colonization, which remained in greater abundances (Porifera), (ii) early colonization, converging (Turf), (iii) slow colonization, converging Anthozoa and Vertebrata), and (iv) slow colonization, remaining lower in abundance (Tunicata and Echinodermata). The environmental relevance of this MREI is considered relatively benign as it covers 0.01% of the surrounding bioregion, appears to be supporting similar assemblages to the surrounding habitat, and exhibited minimal evidence of invasive species (three records of two non-native species). Longer monitoring timescales are required to provide comprehensive, site-specific decommissioning advice.

在与海洋可再生基础设施有关的人工栖息地上开发表皮动物组合

海上海洋可再生能源装置(MREI)将结构引入海洋环境,并且可以局部排除破坏性的底拖网捕鱼。这些影响可能有助于恢复退化的海底栖息地,但可能会受到MREI建设后生态演替的时标和退役期间基础设施的拆除的制约。为了通知管理人员适当的退役策略,在部署后长达5年的时间里,对安装在岩石礁石上的25公里电缆和相关的岩石铠装(英国Wave Hub)进行了监控。上皮组合物的组成和分类单元的数量与周围的对照组相比仍存在显着差异,而在所有调查年份中,电缆和控件之间的丰度都相似。与对照相比,六个吗啉菌在电缆图上显示出四种定殖模式:(i)早期定殖,其丰度更高(Porifera),(ii)早期定殖,趋同(Turf),(iii)缓慢定殖,收敛的花虫和脊椎动物),以及(iv)定植缓慢,丰度保持较低(Tunicata和Echinodermata)。该MREI的环境相关性被认为是相对温和的,因为它覆盖了周围生物区域的0.01%,似乎支持与周围生境的相似组合,并且几乎没有入侵物种的证据(两个非本地物种的三个记录)。需要更长的监视时间表才能提供全面的,特定于站点的退役建议。(ii)早期定居,趋同(Turf),(iii)缓慢定居,趋同于Anthozoa和Vertebrata),(iv)缓慢定居,保持较低的丰度(Tunicata和Echinodermata)。该MREI的环境相关性被认为是相对温和的,因为它覆盖了周围生物区域的0.01%,似乎支持与周围生境的相似组合,并且几乎没有入侵物种的证据(两个非本地物种的三个记录)。需要更长的监视时间表才能提供全面的,特定于站点的退役建议。(ii)早期定居,趋同(Turf),(iii)缓慢定居,趋同于Anthozoa和Vertebrata),(iv)缓慢定居,保持较低的丰度(Tunicata和Echinodermata)。该MREI的环境相关性被认为是相对温和的,因为它覆盖了周围生物区域的0.01%,似乎支持与周围生境的相似组合,并且几乎没有入侵物种的证据(两个非本地物种的三个记录)。需要更长的监视时间表才能提供全面的,特定于站点的退役建议。周围生物区域的01%,似乎在支持与周围栖息地的类似组合,并且几乎没有入侵物种的证据(两个非本地物种的三个记录)。需要更长的监视时间表才能提供全面的,特定于站点的退役建议。周围生物区域的01%,似乎在支持与周围栖息地的相似组合,并且几乎没有入侵物种的证据(两个非本地物种的三个记录)。需要更长的监视时间表才能提供全面的,特定于站点的退役建议。
