An Analysis of Dune Management on the Kenfig, Culbin and Sefton Coasts in the UK Using the SWOT Framework

The stabilization of coastal sand dunes in the 20th century led to an expansion of vegetation cover, which is considered detrimental in the United Kingdom due to the loss of habitat for native species that depend on mobile dunes. Coastal managers have recognized this as a growing concern. However, conservation priorities must be identified to manage the situation effectively. Therefore, this study aims to identify potential conservation priorities for dune habitats at Culbin (Scotland), Kenfig (Wales) and the Sefton coast (England) by undertaking a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis for each site. Variables for the analysis were identified in the context of the latest paradigm of dune management approach, which focuses on the reclamation of active dunes to enhance habitats for native biodiversity. Data was obtained from literature; analysis of environmental, demographic, land use and economic data; and satellite images. The main challenges that emerged include historical overstabilization, the spread of invasive species, the lack of bare sand areas to sustain native biodiversity, unsustainable land use (unplanned urbanization and agricultural activities), coastal erosion due to storm surges, and sea-level rise in this century. Accordingly, potential conservation priorities were determined by classifying variables of each site. These include increasing the area of bare sand, increasing the width of the beach using sand nourishments, removing invasive species, minimizing human activities to reduce dune fragmentation, minimizing coastal erosion due to storm surge and sea-level rise using nature-based solutions. Thus, an integrated sustainable dune management plan is required to implement these conservation priorities, particularly for Culbin dunes as the Cumulative SWOT Score shows that the weaknesses and threats to dunes outweigh strength and opportunities. The study approach demonstrates its robustness as a decision-making tool for sustainable dune management for restoring active dunes at each site. Thus, it can be extended to other dune sites in the UK and elsewhere to identify long-term dune management concerns and conservation priorities.
