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.

Geology & landscape

Geological Period: Permian

Landscape processes: Coastal, Fluvial

Description

Roundham Head SSSI Description This is the type section of the Permian Tor Bay Breccias. These here include a variety of fluvial breccias, in which types formed during ephemeral sheet floods are the most abundant. On the south side of the headland are interbedded aeolian sands showing palaeowind directions towards the north-west. This contrasts with the directions of fluvial transport, deduced from sedimentary structures such as imbrication and cross-bedding in the breccias, which was towards the south-east. A key site for demonstrating Permian sedimentary environments.
