– Damage from constant treading of visitors’ feet
Wind erosion from dominant westerlies heightened by climate change
Wave erosion at high tide events increased by climate change

The management of sand in these beach dunes is to
– specify access pathways across the dunes to the beach,
– Install breakwaters to reduce the effects of strong waves
– Retain grass cover on dunes to protect against wind
Replenish the beach sand from other sites when necessary.
