| Abstract/Contents: | "(1) Classification was made by normal and inverse association analysis of heath vegetation of the Lizard Peninsula, Cornwall. The vegetation types sampled were `Rock Heath', `Mixed Heath', `Tall Heath' and `Short Heath', all overlying serpentine rock and gabbro, and `Short Heath' overlying Crousa Gravels. The analyses produced groups corresponding closely to those previously recognized by Coombe & Frost (1956a). (2) An Erica ciliaris heath near Truro was also sampled and included in the vegetation analyses; this heath showed closest affinity with `Short Heath'. (3) Soils from all heath types were analysed for concentrations of total nickel and chromium, and of a range of exchangeable metal ions. (4) The results of the total analyses, which indicated the contribution made by weathering serpentine to the soils, were consistent with the conclusions of Coombe & Frost (1956b) on the origin of Lizard soils. (5) `Rock', `Mixed' and `Tall' Heath soils had higher concentrations of exchangeable potassium, magnesium and calcium than the more strongly acidic `Short Heath' soils. `Short Heath' soils had the highest concentrations of exchangeable iron. (6) It is postulated that the high concentrations of exchangeable cations, especially calcium and magnesium, in `Tall' and `Mixed Heath' soils are important in restricting the rare species E. vagans to these heath-types. This species was not found in the base-poor `Short Heath' or the exposed `Rock Heath'. (7) The chemical composition of Calluna vulgaris growing in soils of different chemical status remained relatively constant, whereas Erica vagans had higher concentrations of calcium and magnesium in the samples from `Tall Heath'." |
