Implement fisheries management measures for MPA sites that require them to support recovery and resilience of Scotland’s seas (by 2030).
Objective 2: Protect nature on land and at sea, across and beyond Protected Areas
Priority Action 8. Ensure that at least 30% of land, freshwater and sea is protected or conserved and effectively managed to support nature in good health by 2030 (30 by 30)
Implementation of fisheries management measures for Scotland’s Marine Protected Areas (MPAs) is underway, led through Marine Directorate and NatureScot processes, but current measures do not yet deliver consistent ecological recovery across the MPA network. Fisheries management in MPAs is being progressed through site-by-site restrictions, with measures primarily focused on limiting or removing certain damaging activities (including specific forms of mobile demersal gear) in designated features. However, coverage remains incomplete across the full MPA network, and management approaches vary between sites depending on feature sensitivity, gear type and location.
As a result, Scotland is still in a transition phase from designation to fully effective site-based management. While some sites now have protective measures in place, others remain only partially protected or continue to experience pressures from fishing activity that can affect seabed habitats such as maerl beds, flame shell beds and horse mussel reefs. Recovery of these habitats is slow and depends on sustained reduction in damaging pressures over long time periods. Evidence from current implementation indicates that ecological outcomes are not yet secured across the network as a whole. Inconsistencies in spatial coverage, variation in gear restrictions between sites, and the phased nature of implementation mean that the MPA network is not yet operating as a fully coherent recovery-focused system.
Partially. Existing measures represent an important step toward implementation of the MPA network, but they are not yet sufficient to ensure full ecological recovery of protected features at scale. The effectiveness of the network depends on complete and consistent application of fisheries management measures across all relevant sites, alongside effective enforcement and long-term monitoring of ecological outcomes.
Delivery of marine biodiversity recovery requires completion of fisheries management across the full MPA network, ensuring that all sites with sensitive features are adequately protected from damaging activities. This includes closing remaining gaps in spatial coverage and ensuring consistency in management measures across inshore and offshore sites. Management must be explicitly linked to ecological recovery objectives, with clear monitoring of habitat condition and biodiversity response over time. Strengthening compliance and enforcement capacity is also essential to ensure measures are implemented effectively on the water. Long-term success will depend on integrating MPA management with wider marine planning and pressures, including offshore development, climate change impacts, and blue carbon ecosystem protection, to ensure that designated protection translates into measurable ecological improvement.
MPAs protect seabed habitats such as maerl beds, flame shell beds, and horse mussel reefs, which are recognised by NatureScot as highly sensitive ecosystems requiring protection from physical disturbance, particularly bottom-contact fishing. These habitats provide structural complexity, nursery functions, and biodiversity support, but recover slowly when damaged, meaning long-term reduction in pressure is required for ecological recovery. Scottish Government policy identifies MPAs as a key tool for marine biodiversity conservation and recovery, but outcomes depend on effective implementation of management measures. State of Nature Scotland reports ongoing pressures on marine ecosystems, including seabed habitat degradation, reinforcing the need for effective protection to halt biodiversity decline. Overall, MPAs have strong ecological justification, but biodiversity recovery depends on full and consistent implementation of management across the network.

Ensure that at least 30% of land and sea is protected or conserved, as protected areas or Other Effective Area-Based Conservation Measures (OECMs), and effectively managed to support nature restoration.
Based on results from the current pilot, develop and implement a national Protected Areas monitoring programme to ensure that Protected Area sites deliver their objectives.
