Artificial Reefs Boost Marine Life in Strangford Lough

Ten innovative artificial rock pools, known as vertipools, have been installed along the seawall of Strangford Yacht Club, marking a first for Northern Ireland. These honeycomb-style concrete structures, bolted to the wall, are designed to create vital habitats for marine life. The initiative is part of Mourne Gullion Strangford Geopark's 'Greening the Grey' project, focusing on enhancing biodiversity by adapting existing infrastructure.

Marine protected area officer Anna Murtagh explained that the vertipools will hold water, offering a refuge for species and habitats stressed by climate change and increasing sea temperatures. The project aims to significantly increase species richness and variety on the otherwise barren seawall, with hopes of attracting common inter-tidal species like crabs and starfish, as well as unexpected visitors.

Researchers from Bournemouth University have previously found that vertipools can successfully attract diverse sea creatures. Gavin Grant, a Geopark engagement officer, noted the extensive planning, including marine licencing, to ensure the project supports Strangford Lough's protected status. The first pilot run is expected to show noticeable changes within a year, with barnacles and algae being the initial expected inhabitants.

Strangford Yacht Club members see the project as a valuable educational tool for younger generations to learn about marine ecosystems firsthand. The clean waters of Strangford Lough already support rich wildlife, and the vertipools are anticipated to further enhance this diversity, although establishing these new habitats may take about a year. The project also aids in monitoring for invasive species, such as a known invasive barnacle in the area.
