Geodiversity is the link between rocks, landscape, people and culture.

Many human activities have an impact on geodiversity and landscape.

In the Clwydian Range, for example, human beings have left their mark since they built hillforts in the Iron Age. This has continued through lead and spar mining, limestone quarrying and farming. Around Llantysilio Mountain, Ruabon Mountain and Minera Mountain, the landscape contains slate quarries and tips, lead mining pits, shafts, cuttings and spoil dumps.

In places the rocks not only help to shape the landscape, they are attractions in their own right: the limestone cliffs at Loggerheads Country Park, the limestone pavements at Bryn Alyn and Aber Sychnant, the most impressive scree slopes in Britain at Eglwyseg Rocks.

But while the importance of biodiversity is widely understood, fewer people realise that it is underpinned by geodiversity.

Geology influences the plants and animals that live in a particular place because underlying geology determines soil type. If landscape and geology are not conserved and managed, then biodiversity may be at risk.

This remains vital as human influence continues to affect the geological landscape – not just industry and farming but also tourism and leisure activities such as walking, climbing and mountain biking.

Local Geodiversity Action Plan

Local Geodiversity Action Plan

Our Local Geodiversity Action Plan (LGAP) aims to promote collective action to conserve the outstanding geological heritage of the Clwydian Range and Dee Valley AONB. We want to manage its geodiversity in a sustainable way for the social and economic well-being of both visitors and residents.
