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

Description A remnant of the pre-Devensian raised beach platform occurs on Ynys Gwylan Fawr. The islets support an important breeding population of about 800 pairs of puffin, mainly on Ynys Gwylan Fawr, and small numbers of razorbill, guillemot and cormorant. The main floristic species are tree mallow Malva arborea and orache Atriplex sp.. The islands are frequented by grey seals.
