164 THE ESSEX NATURALIST Book Reviews While Some Trees Stand. By Garth Christian. 192 pages. Newnes. 1963. 21/-. This book should be read by every naturalist. Garth Christian tells, in a clear, straightforward, and often amusing manner, the story of wild life in the diminishing British countryside, and of the unprecedented dangers confronting wild life to-day. The decline of many of the species so long taken for granted, such as the nightingale, cuckoo, peregrine falcon, sparrow hawk, red squirrel, weasel, and stoat, is described, and a warning given that unless there is still greater support for conservation some of our most cherished wild creatures will surely cease to exist. The argument has been heard that serious naturalists should concern themselves only with their studies, and remain aloof from the issues of conservation. In case there are still a few misguided individuals who hold this sad view, it must be emphasized that all naturalists, of all levels of proficiency, have a duty to take an active interest in the conservation of wild life. Responsible nature conservation is vital for at least three reasons. Firstly, because as trustees of the Earth and its creatures of millions of years of evolution, we have a moral responsibility to see that no destruction takes place that can be avoided. Secondly, because the beauty of nature must be preserved for our descendants. Thirdly, be- cause to destroy wild life is to destroy sources of biological information which may prove of almost unbelievable importance for the future of Mankind, in view of the development of biological science. The British countryside shrinks each year by an area larger than the whole of Warwickshire, and as the human population continues to in- crease, the woodlands and hedgerows disappear under concrete and sprayed fields. The more one learns of the facts of the problem, the more one realizes the urgency of the need to conserve what is left of our natural heritage. An outstanding feature of Garth Christian's book is the admirable fair- ness with which the author examines each question, showing the need for conservation with full regard for the needs of agriculture, forestry, and so on. The book contains some first-class natural history, and is well worth reading for its observations alone. There are several excellent illustrations, including one of the Hales Wood National Nature Reserve in Essex. In his conclusion, Garth Christian points to the need for more research into ecology and conservation problems, and for more public notice to be taken of the findings of scientists. No less vital is the need for awareness by the general public of the importance and urgency of the matter. As Mr. Aubrey Buxton has said of nature conservation, quoted by Mr. Christian, for perhaps four-fifths of our population "the very words convey no more than a vague impression of Women's Institute members bottling jam". The author also points out that a large section of the public regards the naturalist as a crank, "a bug-hunter whose hobby is no more
