About us

Chalk MicrographThe Berkshire Geoconservation Group is a volunteer group which works with local authorities, landowners and the general public to safeguard our special landscape for future generations and to promote understanding of its geology and geodiversity.

We designate sites of significance within the county so that these can be conserved and enhanced where appropriate. We also produce a Local Geodiversity Action Plan which identifies actions to be taken over a five year period. Blackwater Gravels This aims to guide the conservation and interpretation of the geological features of Berkshire.

If you are interested in any aspect of geoconservation please consider joining BGG. Even if you do nothing else with the group, by simply becoming a member you will be making a big difference. Membership is free and all members receive news and information about our activities.

Over the year we have a regular programme of walks to areas of geological interest and anyone is most welcome to join us. If you would like to suggest a walk of interest then please do so. We are always happy to give talks to local groups about the geology of the area.
