Jon Wyatt Photography - Disused Limekilns in salt marshes at East Aberthaw, South Wales
Disused limekilns in salt marshland, East Aberthaw, South Wales. Salt marsh ecosystems, which exist in the inter-tidal area immediately behind the coastline, are, per unit area, the most productive habitats on earth. The salt marshes which were known to line the Bristol Channel coast were almost entirely destroyed by the tsunami of 1607 leaving the population exposed further flooding.
