Apart from the relative density of holly and the presence of Scots pine and bilberry, the overall mosaic pattern of heathland and wood has some simlarity to areas of Epping Forest in the past. One such area was Rushey Plain, at High Beach; today it consists of a mixture of old pollarded beeches, oaks and hornbeams, plus younger birch woodland that has invaded the former glades. A comparison of the breeding birds of the New Forest and Rushey Plain sites for the spring and summer of 1976 (Table 2) showed the total number of species in each area to be virtually the same, with 21 in Epping as against 22 in the New Forest. The average number of territories per square kilometre, however, was greater for the New Forest, probably reflecting the greater diveristy of habitat. It should however be noted that all the species recorded for the New Forest site during 1976 also breed in Epping Forest. One of the few localities for which detailed information about changes in the bird community is available is Bookham Common, Surrey. Although, of course, smaller, like Epping Forest it contains a mixture of mature woodland, grassland and scrub. The bird community at Bookham has been well documented over a long period of time in the London Bird Report and has made 11
