Climate exposure

This is about exposure to a nationwide pressure this habitat type carries — not a verdict on this site's own management.

Coastal

Coastal habitats are exposed to sea-level rise and storm erosion. Where hard sea defences sit behind them, there's nowhere landward to retreat to — a squeeze that keeps compressing the habitat no matter how well it's managed.

Description

Dawlish Cliffs SSSI Description Dawlish Cliffs shows one of the finest continuous exposures of interbedded Aeolian sands (Dawlish Sands) and water-laid, breccia-filled, fluvial channels of Permian age in the country. At the northern end of the section, Langstone Rock is the type section of the Langstone Breccias, a coarser sedimentary development within the main body of the Dawlish Sands. The coastal cliff section at Coryton’s Cove shows a major aeolian sandstone unit of Permian age some twenty metres thick. The junction of the underlying Coryton and Teignmouth fluvial breccias is also seen. The Teignmouth breccias include flat-bedded and normally graded deposits produced by sheet floods and also matrix-supported debris flows. They form a coarse and very thick basal unit of the local Permian succession.
