VEGETATION OF THE MARITIME CLIFF‐TOPS OF THE LIZARD AND LAND'S END PENINSULAS, WEST CORNWALL

Abstract

The maritime cliff‐top vegetation of the Lizard and Land's End, West Cornwall, is described in a traditional phytosociological manner. Six new associations are described, together with a number of other noda. The noda are related to environmental factors and the zonation on the cliffs is found to be determined by the amount of exposure to maritime influence, with further variation due to differences in soil depth and moisture content and to the geology of the underlying rocks. A strongly marked relationship between the percentage of maritime species in a nodum and the sodium‐organic ratio is noted. Copyright © 1971, Wiley Blackwell. All rights reserved
