possible exception of areas in the extreme north. Roe deer from Germany were released in Suffolk, near Thetford, in the late nineteenth century (Noble, 1903). The descendants of these deer are now extremely numerous in Thetford Chase and they have gradually spread south through Suffolk, Beale (1974) recording fair numbers as far south as Lineage Wood (TL8848) at Long Melford and Stanstead Great Wood (TL8548) at Stanstead, only 3-6 km north of the Essex border. Roe deer have been present in north Essex since about 1963 but even now, 13 years later, they are far from common in the county. These animals are probably pioneering individuals and it seems likely that in the future, roe deer will become more common in the county. Sika Deer None of the post-1964 records of wild sika deer in Essex can be sub- stantiated. Fallow deer abound in all the areas where sika were reported and it is probable that fallow deer were incorrectly identified as sika. The sika deer reputed to be in Hatfield Forest remains a mystery. The photograph was said to have been taken in mid-July but the animal was in winter coat, with a shaggy mane and hard antlers. Sika stags usually have hard antlers only from Sep- tember to April (Horwood & Masters, 1970) and so the photograph itself is a mystery. Perhaps the animal was an escapee from one of the nearby wildlife parks at Stanstead or Widdington. The nearest wild sika deer are probably those in the New Forest in Hampshire although there may be feral animals in Kent (see Corbet, 1971). General discussion At a time when there is probably more talk than ever before about the need to conserve our flora and fauna, it is pleasant to be able to report that the Essex countryside has never been so well off for deer as it is today. Wild deer are now common over much of north and west Essex, whereas at the turn of the century they were restricted to Epping Forest and adjoining estates. Four species are present today whereas only one, the fallow, was present 50 years ago. The main part of the Essex Deer Survey was carried out, fortuitously, just in time to enable the spread of muntjac and red deer in the county to be dated with some accuracy. Unfortunately, much of the spread of fallow probably took place or was well under way by the time the Survey started. Deer have become more widespread in Essex despite the great increase in urban development and mobility of the population that has occurred this century. In fact, deer are living in extraordinary close proximity to towns. Both wild fallow and muntjac are frequently seen, and breed, in Latton Park and Mark Bushes situated adjacent to Harlow New Town with its 80,000 inhabitants. Appreciable numbers of wild fallow deer may be seen from houses on the edge of Harold Hill and Harold Wood, situated within the boundary of Greater London. By contrast, the fallow deer in Epping Forest have declined greatly over the last couple of decades, the animals having moved largely to adjoining estates. This decline has been at- 37
