SIBs (Significant Isles of Britain and Ireland) - The SIBs are defined as "naturally occurring land which at MHWS is completely surrounded by water with either an area of at least 30 hectares within the MHWS contour line or an 'easily accessed' summit with prominence of at least 30 metres above MSL, or both, all man-made links and structures being discounted". The definition of 'easily accessed' summits are those that can be comfortably ascended by walking, involving nothing more challenging than easy grade 1 scrambling. They were researched by Alan Holmes.
Initially confined to Britain, in August 2018 the list was extended to include Ireland, Isle of Man and the Channel Isles.
