Maritime cliff communities in the British National Vegetation Classification system
# Maritime cliff communities in the British National Vegetation Classification system

This article gives an overview of the maritime cliff communities in the British National Vegetation Classification system.

## Introduction

The maritime cliff communities of the NVC were described in Volume 5 of British Plant Communities, first published in 2000, along with the other maritime communities (those 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)

## List of maritime cliff communities
