Competition for maritime space leads to conflict between human activities and ecosystem conservation, which can be resolved by Marine Spatial Plans. High-resolution maps of Essential Fish Habitats were used to model potential distributions of important species in English and Welsh waters. The Celtic Sea and North Sea coastal areas are identified as crucial spawning and nursery grounds. High pressure from human activities is expected to impact Essential Fish Habitats in certain areas.
Competition for maritime space generates conflict between human activities and ecosystem conservation; Marine (Spatial) Plans provide conflict resolutions and clarify trade-offs. Spatial plans require appropriate scales, reliable maps of sites important to marine organisms. We present maps of hotspots of Essential Fish Habitats (EFH) at a high spatial resolution for English and Welsh waters. These outputs can be integrated into an improved spatial plan for these waters. We modelled the potential distribution for different life stages of commercially and ecologically important species, as a high-resolution indicator of the distribution of essential fish habitats. Model outputs were combined with observed, low-resolution fish distributions to derive 'hotspot' spawning and nursery areas. The Celtic Sea and coastal areas of the North Sea are highlighted as important spawning and nursery grounds. High pressure from human activities is expected to impact EFHs in the English Channel and the central-east Celtic Sea. Our approach maintains the high resolution of the model-derived maps while filling in information gaps. As fish share essential habitat preferences, protected hotspot areas are expected to sustain a multitude of species. Overlaying human activities, such as fishing, on the hotspot maps allows managers to identify areas of conservation interest and apply appropriate measures. The method is directly applicable to other areas and can be extended to use multiple sources of data for model development. Crown Copyright (C) 2021 Published by Elsevier B.V. All rights reserved.
