NATURE CONSERVATION: ESSEX 85 Nature Conservation, with Special Reference to Essex By T. H. C. Bartrop, F.R.S.H.* The subject of nature conservation is one which has recently received much publicity—and not only in this country. The movement is now gaining momentum, but to many places it has come too late to save a number of species of the flora and fauna and their habitats. It is far too easy to become emotional when discussing this subject, but the true conservationist must base his case on sound, scientific knowledge and put it forward in a sane and balanced manner. The problems involved in maintaining this sane and balanced outlook are, however, not solely county, regional or even national in scope. They are also international. At the 1961 Arusha Conference, held under the auspices of the International Union for the Conservation of Nature, the theme was the conservation of African wildlife and natural resources. It will be remembered as the occasion when the first official declaration in favour of wild- life conservation was made by any government in the world. This manifesto from the host country, Tanganyika, declared, "The survival of our wildlife is a matter of grave concern to all of us in Africa. These wild creatures amid the wild places they inhabit are not only important as a source of wonder and inspiration but are an integral part of our natural resources and of our future livelihood and well-being. In accepting the trusteeship of our wildlife, we solemnly declare that we will do everything in our power to make sure that our children's grandchildren will be able to enjoy this rich and precious inheritance. The conservation of wildlife and wild places calls for specialist knowledge, trained man- power and money, and we look to other nations to co-operate in this important task—the success or failure of which not only affects the continent of Africa but the rest of the world as well". This was signed by the Prime Minister, Mr. Nyerere, and his Ministers for Legal Affairs and for Lands and Surveys. In the same year, The World Wildlife Fund, under the patron- age of H.R.H. The Prince of the Netherlands, was launched to raise at least half-a-million pounds a year to save the wildlife of the world. In our own country, the problems facing the nature conserva- tionist were excellently stated in the 1959 publication of The Nature Conservancy entitled, "The First Ten Years". "Our country, as we used to know it, is vanishing before our eyes. We see its coasts and fields chosen as sites for houses and power *Presidential Address delivered 23rd March 1963.
