L. DUDLEY STAMP’S Britain’s Structure and Scenery was one if the earliest books of The New Naturalist Library, published in 1946. Repeated . later editions in the period to 1986 testified to the success of his approach towards providing a geological framework for understanding Britain’s landscapes and natural history. He began his account in these words: ‘The wealth of a country’s fauna and fauna and flora is not to be measured by numbers of species alone. Its wealth lies rather in variety, and to a naturalist in the British Isles, the fascination of the native fauna and flora is in the great variety to be found in a small space.’ This variety has its foundation in the underlying geology and the landscapes which are derived from the geology, as Dudley Stamp described so well. For some time, it has been the ambition of the Editors to approach this subject again, since our understanding of the geology and associated landscape evolution has increased so very significantly in the last few decades. The author, Peter Friend, has had long experience of active field research in geology and landscape in many parts of the world, as well as having an intimate knowledge of the subject in the British Isles. He has been able to take full advantage of modern developments in computer mapping and colour printing, making it possible to present the subject in a novel fashion, with great clarity, following the New Naturalist tradition emphasising the importance of illustration. The individual treatment of regions and areas of Southern England brings to the fore the significance of geology and landscape for naturalists who have local or wider interests at heart, giving a necessary basis for relating biodiversity to geodiversity. These two aspects of natural history have come to be seen to be widely significant in understanding plant and animal distribution as well as the problems of conservation. The book is therefore a very ti mely addition to the New Naturalist Library.
