What is in or out?• Ten year trends %• Dunlin -23• Bewick Swan -75• Whooper Swan 22• Shellduck -59• Redshank -1• Gadwall 82
Water resources- Lower Summer flows?
• Salt ingress• Dredging costs• Oxygen depletion• Salmon Migration
Aggregates dredging• Domestic energy reduction =
new houses= aggregates• Welsh demand largely from
Bristol Channel• Possible erosion to beaches
and cliffs• Further pressure inland
