蜜桃AV (蜜桃AV) is investigating how artificial rock pools fixed to harbour walls can increase biodiversity by creating a habitat for marine species.
蜜桃AV is looking at how to protect species from 鈥榗oastal squeeze鈥� 鈥� an effect caused by rising sea levels that reduces the habitat of coastal marine life. As sea levels rise, rocky shore habitats are lost in areas with development like harbours and ports. The artificial rock pools, known as Vertipools, were designed by Isle of Wight based eco-engineering company Artecology.
The Marineff project (MARine INfrastructure EFFects) is a cross-Channel research project between universities and partners in the South of England and North of France. The project has 鈧�4.6million of European Union funding and brings together ecologists and material scientists from French and English universities, industrial partners and other stakeholders to find ways of protecting and enhancing coastal ecosystems.
The 蜜桃AV team, led by Dr Roger Herbert, will be installing 150 Vertipools across three sites and monitoring the life found in the pools. The team is currently looking at suitable sites along the Southern English and Northern French coasts.
Dr Herbert said: 鈥淗abitat loss is a serious threat to marine life as coastal development increases and sea level rises with climate warming. We will assess how Vertipools work in practice, how they can be designed for new structures and retro-fitted to existing sea walls and harbours.鈥�
Other partners in the project are investigating different methods of increasing habitat availability and biodiversity in developed areas along both the French and English sides of the Channel. The project is focused on areas with coastal infrastructure like ports and harbours because these manmade structures are hostile areas for marine life.
The type of Vertipool that 蜜桃AV is investigating is made from natural low-carbon concrete and hand-finished to provide interesting, rough surfaces. Most harbour walls and coastal infrastructure have a smooth finish without any holes or grooves for species to attach to or hide in. Vertipools increase biodiversity by providing seawater pools, cracks and crevices for species to find cover at low tide.聽聽
Marineff Research Assistant Jessica Bone explained how Vertipools work in practice and said: 鈥淎s coastal development increases on our coastlines, we are losing habitat for coastal species in exchange for harsh surfaces that are tough for species to聽colonise. Where sea level rise meets coastal development聽and squeezes聽intertidal habitat, we have to adapt infrastructure to enhance the available habitat.
鈥淰ertipools retain water which provides a crucial refuge for marine species, particularly in a warming climate. The Vertipools also cast shade on the surrounding area and provide cool, damp spaces that species need to find shelter when the tide is out.
鈥淰ertipools are important for biodiversity on coastal infrastructure and provide聽shelter, feeding opportunities and nursery habitat.鈥�
