BEETLES IN EPPING FOREST by PETER HAMMOND Dept. of Entomology, British Museum (Natural History) London S. W. 7. INTRODUCTION Occasioned as it is by the Centenary of the Epping Forest Act of 1878, it would be appropriate in this review of the Forest's beetle fauna to discuss changes which have taken place during the past one hundred years. Indeed, provision of an historical "back-drop" of this type might be seen as an essential preliminary to a commentary on the Forest's present fauna, to comparisons with the faunas of other old forests and areas of park-woodland, and to a discussion of conservation needs. However, as is so frequently the case in matters relating to the distribution, frequency and abundance of species of beetles in the British Isles (see Hammond, 1974), data regarding the beetle fauna of Epping Forest available in published, or otherwise readily accessible, form are a poor basis for any discussions of this kind. Regrettably then, the major part of the present paper represents an attempt to supplement the data base itself. Additional data are presented here in a much summarized and contracted form. In the limited space available it has not been possible to detail and document to any great extent, but it is hoped that this information, along with that concerning other parts of Essex, will be made available in due course. Data presented here derives from an account of the beetle fauna of the county as a whole (Hammond, unpublished work). I have attempted to include a good measure of analysis and comment on the beetle fauna of the Forest by combining this with the new data to be presented in the form of tables below (notably Tables 6 & 7). More extensive comment is brief, but touches on the contribution which a fuller knowledge of Epping Forest's beetle fauna might make to our understanding of the relict fauna and flora of those tracts of mature British woodland which have had a more or less uninterrupted existence during the past 8,000 or so years. In particular, I have referred to the use of certain beetle species as indicators of Old Forest conditions. HISTORY OF THE STUDY OF EPPING FOREST COLEOPTERA A number of British entomologists in the immediate post-Linnaean period and the early nineteenth century collected beetles in the Epping Forest area. 43
