Soil composition of exchangeable elements (nickel, calcium, magnesium, calcium : magnesium ratio, iron, copper) and physicochemical characteristics (e.g. pH, cation exchange capacity, conductivity, carbonate) were investigated and the species composition and cover were recorded. Although there was a significant difference between the two types of soil shown by Student's t-test and principal component analysis, the 'serpentine factor' can be considered moderate on the basis of the observed heavy metal concentrations and of the related calcium : magnesium ratio. Correspondence and canonical analysis were used to detect the principal factors associated with gradients in species composition. This analysis showed a clear differentiation of vegetation am...

The gardens were established from 1867 by Sir Thomas Hanbury with the aim of acclimatizing several rare botanical species coming from all the temperate climate regions of the world. Many restoration works have been executed, and to this end an extended sandy layer located on the upper portion of the property was used as building material: it was extracted from weakly cemented yellowish sands probably belonging to the top of the Pliocene Ortovero clay formation. The artificial cave opens up to about 90 m a.s.l. and has a total length of 133 m and a maximum difference in level of 8 m; the total volume extracted is on the order of 1,500 m3 and the internal stability seems guaranteed by some stone pillars. The NE portion of the underground quarry has not been surveye...
