Britain (now the British Geological Survey, BGS)

and its experienced field staff, provided the geological basis for geoconservation. Evolving activi-ties of the Survey from primary survey and collecting to revision mapping to 3D/4D-modelling reflect changing national needs. In turn, BGS has developed its capability to provide new geologi-cal interpretations and a range of publications raising the profile of Earth sciences, both for professionals and for the popular market. Today, BGS’s input through networks to geodiversity projects and to newly designated regions such as Geoparks marks a major transition towards a proactive geoconservation agenda in the twenty-first century
