The Essex Naturalist 93 Table 1: Nitrogen analysis of grazing material in the forest and bufferlands Visual Assessment Coat colour of the deer on the bufferlands was recorded. This was indicative of whether black deer were moving to the bufferlands, or whether black deer were simply dying out in the forest. Nine evening watches were organised. The earliest of these was in May, the latest in July. The route taken was the same each time to try to identify where groups were naturally located (rather than where they had retreated to after observing the car). The route was as follows: The Forest Way to Woodredon Bridge, Oxleys Wood, Fernhall Lane, Long street, Rookery Wood, Copped Hall, The White House, Little Rookery Wood, Spratt's Hedgerow and Copped Hall Park. Numbers and colours of all deer seen were recorded. If there was any doubt as to whether a deer had already been counted during the duration of an evening's watch, then that deer sighting was disregarded. It should be noted that during the period of the watches, deer were associating in small groups only; fawns were dropped in June.
