The Common is a living and working landscape, steeped in history but sadly we often take this for granted. It is a designated Cadw Historic Landscape due to evidence of continued land use and activity from prehistory to the recent past.

It is a landscape that links the communities who live around it, our Common is a vital green lung of the valleys. At 3,000ha this great expanse of land plays its part in the water and carbon cycles, which shape and support our everyday lives locally, nationally and internationally.

The Common means so much to so many people. For some it is an area to graze animals, to others an open space for health and wellbeing. Some enjoy the rich biodiversity and historical assets, while others may just enjoy it as scenic route to work.

Whatever your passion there is a common thread, it is the landscape that binds the local area together.

While the Common may be rooted in centuries of history the Common is just as relevant to many of our 21st Century challenges –rural economic sustainability, food quality and security, physical and mental wellbeing, flood management, biodiversity and climate change.

There is something autumnal about foxes. Maybe it’s the fact that the colour of their coats reminds us of dried, fallen leaves. Or maybe it’s because, as the days shorten, there is more chance that we’ll be out walking at the same time as the fox wends his way back to...
