RP04518 Edition 1 Compilation and Review of Evidence Leading to SANG and SAMM Provision (RP04518)

The study reviews 16 Local Planning Authority (LPA) case studies to understand the methods and evidence used for mitigating potential recreational impacts arising from housing growth on ecologically sensitive sites, particularly European designated sites. Mitigation strategies such as Suitable Alternative Natural Greenspace (SANG) and Strategic Access Management and Monitoring (SAMM) measures have been implemented to alleviate these pressures.

The research project involves three stages: data gathering, compilation/summary of evidence, and review of evidence quality and policy approaches. Key stages in mitigation include identifying triggers, gathering quantitative and qualitative evidence, implementing solutions (mainly SANG and SAMM projects), communication with stakeholders, and monitoring and reviewing the effectiveness of mitigation strategies.

The review concludes that best practice in securing mitigation solutions includes: maintaining a robust and periodically updated evidence base; establishing Zones of Influence (ZOI) for mitigation; exploring bespoke mitigation options; adopting a partnership approach; ensuring evidence-based guidelines; promoting communication with stakeholders; and implementing a comprehensive monitoring strategy.

Furthermore, the review suggests exploring links between mitigation solutions and wider initiatives such as Green Infrastructure (GI), Local Nature Recovery Networks (NRNs), and Biodiversity Net Gain (BNG) to achieve multifunctional benefits for ecosystem services. Evaluating these wider benefits is recommended for effective planning and implementation.
