REEFS – Researching Ecosystem Functioning in Vulnerable Marine Habitats: Cold Corals in Bratten

Title: REEFS – Researching Ecosystem Functioning in Vulnerable Marine Habitats: Cold Corals in Bratten

Description: The REEFS project will investigate the ecological functions of cold-water corals in the marine protected area of Bratten in Skagerrak. This area is home to seven red-listed coral species that play a critical role as "ecosystem engineers," enhancing biodiversity and providing habitats for fish and invertebrates. Despite their ecological value, previous studies have not specifically focused on the corals' ecological functions. The project will analyse three zones with varying levels of human impact: a fishing-free zone, a buffer zone, and an actively fished zone. The project will focus on three key coral species: Lophelia pertusa, Paragorgia arborea, and Swiftia and examine biodiversity, coral food webs, and reproductive capacity using tools like underwater robots, fatty acid and sotope analyses, as well as video mapping. The project integrates biological studies with communication, disseminating findings through workshops, a GIS database, and public activities. The results will provide deeper insights into the role of cold-water corals in Bratten's ecosystem and their responses to human activities, contributing to improved management strategies that balance biodiversity conservation with sustainable fishing. Practical applications include scientific guidance for decision-making in marine conservation strategies and management plans.
