These habitats were chosen as they occurred within English waters and were known to have some possibility for active or passive restoration interventions. This project uses a spatial analysis approach to investigate the current, historic, and potential future distribution of these habitats in English waters (out to 200 nautical miles (nm) from the shore). This report provides the first investigation and mapping of marine restoration potential in English waters. Although the modelling approaches chosen for the different habitats vary, the restoration potential for some habitats (such as kelp forest and native oyster beds) appears greater than for others such as the maerl beds, horse mussel beds and seapen and burrowing megafauna habitats. There is a need for further refinement of the restoration potential models to improve both the confidence of the models and remove areas of hard constraint where restoration would not be possible. There is also a need to future-proof areas of potential restoration by including limitations from climate change. Further opportunities to develop this work refine areas for restoration as well as developing pilot restoration handbooks and testing the viability of restoration zones with on the ground pilot studies would be beneficial.

Although the habitats covered in this study (kelp, maerl, native oyster, horse mussels and sea pens and burrowing megafauna) are distinctly different in their current and historic extents and distributions in English waters, these habitats also have some similarities: They all act as ecosystem engineers that provide habitat complexity, structure, and resources for associated marine fauna and flora. These habitats also provide important ecosystem services such as water filtration, sediment stabilisation, habitat provision for commercially important species, and climate change mitigation via flood risk alleviation and/ or carbon storage. However, these habitats tend to be highly sensitive to ecological and environmental factors, anthropogenic impacts, and the effects of changing climate. The report included in this series consists of five habitat-specific sections; one for each habitat included in the MaRePo project (kelp beds, maerl habitats, native oysters, horse mussel beds and sea pen and burrowing megafauna communities). Each habitat-specific section includes a critical literature review on biology and ecological importance, habitat distribution and factors affecting habitat distribution, and the previous restoration approaches trialled for the habitat. The results sections show the collated data on current and historic distribution of each habitat, as well as the proof-of-concept models on habitat restoration potential based on key physical attributes specific to each habitat. The restoration potential maps vary considerably between the habitats included in this study, due to differences in availability and quality of existing abundance and distribution data between the habitats, as well as our understanding on the biotic and abiotic factors and the thresholds for impact on distribution of each habitat. The lineages for each individual habitat dataset are included in the dataset level MEDIN Discovery Metadata in each data package.
