CONSERVATION AND FUTURE STUDY Of the 1371 beetle species recorded from Epping Forest in the broad sense, about 100 have not been found there since 1900. Most of the more significant of these are listed in Tables 6 and 7. Perhaps 35 of these, in my estimation, are now likely to be extinct in the Epping Forest area. This number includes a few, such as Onthophagus nutans (Fabr.) (Allen, 1965), which are probably extinct throughout the British Isles. Progressive encroachment and interference with areas of primary woodland is undoubtedly an important factor in such ex- tinctions (see Hammond, 1974, for a discussion of extinctions in the British beetle fauna as a whole). However, the Old Forest species of the main body of Epping Forest do not appear to have suffered too badly during the present century. Only two of the 93 Old Forest indicator species recorded from Epping Forest sensu Buck (1955), have not been collected there during this century. Of the additional 23 indicator species not seen in the Forest since 1950, most may be expected to still occur. Visits to the Forest in the past twelve months demonstrate that some Grade 1 indicator species, such as Prionocyphon serricornis and Batrisodes venustus, may still be collected without too much difficulty. Conservation measures suited to maintaining populations of the insect species most typical of Old Forests have been discussed by Chalmers-Hunt (1969), Hammond (1974), Harding (1977), Johnson (1974) and Stubbs (1972), and there is little to add to the suggestions made in these papers, although the importance of leaving dead and dying wood in situ can not be overstressed. In Epping Forest, mature beech and oak trees are deserving, because of their exceptional insect faunas, of the conservationist's special attention. Coppicing and pollarding is unlikely to be greatly deleterious, unless indiscriminate or on a very large scale. Some of the existing and mature pollarded beeches support numbers of the more interesting beetle species. The coleopterological interest of the Forest's ponds and open spaces has been noted above and preservation of some of these features in a relatively stable condition is to be advocated. There remains much to interest the student of British Coleoptera in the beetle fauna of Epping Forest. As so little careful collecting of beetles has been done in the Forest in recent years the present status there of many species, particularly those typical of Old Forests, should be investigated. How many of these, including the total of 25 not seen there in the past two decades or so, are still to be found? Much remains to be discovered concerning the feeding behaviour and life cycles of the Old Forest species and, in the case of some of these, Epping Forest presents one of the best opportunities in Britain of in- vestigating these matters.
