Included here are the volcanic islands of St Helena and Ascension situated in the South Atlantic.

St Helena Sea Cliff Formations

The cliffs on St Helena can be up to 500 m high, but most of them are composed of layers of eroding rock and loose volcanic ash. The dry western cliffs are virtually devoid of vegetation, but the wetter eastern and southern cliffs support a scattering of plants, including number of endemics that have become extinct in other parts of the island such as Pelargonium cotyledonis (Geraniaceae) and Plantago robusta (Plantaginaceae). Sea cliffs are therefore considered to be of great importance for conservation.
