GCR (Geological Conservation Review) Site lists

Geological Conservation Review (GCR) sites form the basis of statutory geological and geomorphological site conservation in Great Britain. In total, there are over 3,000 GCR sites, selected for around 100 categories (GCR Blocks), encompassing the range of geological and geomorphological features of Great Britain.

Provided here are the lists of GCR sites across England, Scotland and Wales. Sites are grouped by GCR Block. A summary of the blocks, along with the number of sites within each block, is provided below, with links to the site lists for each block.
