SNH’s Adaptation Principles

Laggan Peninsula & Bay SSSI

DRAFT Adaptation actions

  • 1. Reduce other pressures

(outwith Principle 4)

  • 2. Make space for natural

processes

  • 3. Enhance opportunities for

species to disperse

  • 4. Improve habitat management
  • 5. Enhance habitat diversity
  • 6. Adaptive approach to

conservation management

  • 7. Plan for habitat change
  • 8. Consider translocation of

species Build contingency for locally increased dune dynamism into grazing regimes X X X X Continue to foster community understanding of need to avoid recreational damage X Seek ways to protect dune habitat that migrates

  • r expands outwith current SSSI boundary

X X X Encourage Machrie golf club to embed detailed adaptation to dune erosion X X X X? Engage with airport re use / location of runway without need for coastal defences X X
