St Just Moors (Lower Bostraze & Leswidden)
South West England
Location: Between St Just and Penzance, either side of the A3071, at the far west of Cornwall.
Grid Reference: SW 385 314
Like the St Austell Clay pits, the pits at Lower Bostraze and Leswidden are now-disused china clay quarries.
The exposed clay waste and decaying granite rocks here support important populations of the internationally very rare liverwort western rushwort. This is one of only two sites in the UK where it exists.
The clay surfaces are also colonised by the flilamentous green freshwater algae known as desmids for which this is a site of international importance.
