The SIBs

A SIB is a "Significant Island of the British Isles".  The complete list of SIBs and Squibs comprises over 1600 islands.  The qualification criteria are to be an island with at least 30 hectares of area or a prominence of 30m.  Islands whose ascent is restricted to rock climbers (sea stacks etc) are excluded from the SIBs.
