Introduction
The maritime cliff communities of the NVC were described in Volume 5 of shingle strand-line and sand-dunes and saltmarshes) and vegetation of open habitats.
In total, 12 maritime cliff communities have been identified.
The maritime cliff communities consist of three subgroups:
- five maritime cliff crevice and ledge communities (MC1, MC2, MC3, MC4 and MC5)
- five maritime grassland communities of sea-cliffs (MC8, MC9, MC10, MC11 and MC12)
- two communities associated with sea-bird cliffs (MC6 and MC7)
