CLIMATE-CHANGE ADAPTATION FOR COASTAL HABITATS - learning from geodiversity nick.everett@nature.scot Policy & Advice Officer – Coastal Geomorphology SNH Balmedie dunes, Aberdeenshire

N2-4 manage designated sites - ID consequences & put in place adaptive measures N2-20 adaptive coastal management that works with natural processes… identify habitats most vulnerable to erosion & SLR

Extrapolating the 1980- 2014 change into the future gives projected change: in this case erosion to 2050

PROJECT 2 Adaptation planning for coastal designated sites [physical change only] erosion projections (Dynamic Coast) + geomorph reasoning including SLR = anticipated physical changes

SNH’s Adaptation Principles 4. Improve habitat management 3. Enhance opportunities for 5. Enhance habitat diversity 8. Consider translocation of 1. Reduce other pressures conservation management 7. Plan for habitat change 2. Make space for natural 6. Adaptive approach to (outwith Principle 4) species to disperse Laggan Peninsula & Bay SSSI processes species DRAFT Adaptation actions Build contingency for locally increased dune X X X X dynamism into grazing regimes Continue to foster community understanding of X need to avoid recreational damage Seek ways to protect dune habitat that migrates X X X or expands outwith current SSSI boundary Encourage Machrie golf club to embed detailed X X X X? adaptation to dune erosion Engage with airport re use / location of runway X X without need for coastal defences 6 & 7 – moving outwith existing conservation framework?
