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

BOGSIDE FLATS Bogside Flats, situated around the common estuary of the Rivers Irvine and Garnock, contains the only extensive expanse of saltmarsh and mudflats between the Solway Firth and the Inner Clyde Estuary. The biologically productive saltmarsh and mudflats are the best example of this habitat type in Ayrshire and displays a variety of plant and animal communities representative of different degrees of tidal inundation. The upper, middle, and lower saltmarsh habitat zones are present, which is unusual as lower saltmarsh is not common in Scotland. Transitions from saltmarsh to terrestrial habitats are also present and intact.
