urban sprawl of Enfield. Several visits were made in 1965-1967 to Scales Park at Nuthampstead, High Wood at Wenden Lofts and Rowney Wood at Debden but no signs of muntjac deer were found in any of these areas. The Forestry Commission's Forester also considered that Rowney Wood was free of deer at that time (Waters, personal communication). In January 1971, Beale first saw muntjac in this part of Essex, in Rowney Wood and Scales Park, although he did not see them in High Wood until 1976. It is not clear from where the deer came. There was the unconfirmed report of a muntjac deer at Pampisford, Cambridgeshire in 1963 and a dead animal was found a few kilometres away at Fowlmere, also in Cambridgeshire, in 1967. The only muntjac deer records from the adjacent area of Hertfordshire are post-1974. The deer may, however, have spread north- wards from the Great Dunmow area to Rowney Wood and then to the other areas. There have been several records of single muntjac suddenly appearing in urban areas. Possibly these animals have travelled along corridors of vegetation, such as those provided by narrow strips of land bordering railway lines, until the deer are trapped in built-up areas. The presence of the single animals recorded at Chelmsford, Chingford, Enfield and West Ham may be explained in this way. The single animals found at Chelmsford, Chingford, Gosfield, Halstead, Walton-on-the-Naze and West Ham were all young males and this may be significant. Dubost (1971), in a study of both the Indian muntjac (M. muntjak (Zimmermann)) and the Chinese muntjac, states that the young males are driven out of the family group during their second year by the adult male. Seear's (1964) belief that the Indian muntjac may be present in the county has not been confirmed. Fallow Deer At the end of the nineteenth century, fallow deer in Essex appear to have been restricted to the Epping Forest area and to enclosed deer parks (Laver, 1898), now they are widespread over much of the north and west of Essex. What has caused this dramatic spread of fallow deer? The distribution of the deer themselves provides a clue to the answer. With the exception of the Epping Forest group of deer, several of the other groups are located close to a deer park or a recently disbanded park: compare Maps 1 and 4. The Navestockside group of fallow deer are almost certainly descendants of animals that escaped from Weald Park (Plate VIII). Local inhabitants claim that deer were unknown in the surrounding woods before the Second World War. Similarly, the Markshall group of fallow are based on the former deer park at Marks Hall. The Hatfield Forest group of fallow probably originated from this area when it was an en- closed park and possibly from Hallingbury Park which was adjacent. Deer from Easton Park may also have contributed to this group, although most if not all were killed in 1939. Mrs Spurrier informs me that the fallow deer only began to be seen in the area of the former deer park in the mid-to-late-1950s and that in 33
