29 being cleared and dense hawthorn scrub has already colonised the earthworks, bearing a generous harvest of berries for many birds and offering good cover to high populations of rabbit and fox. The tram lines have been removed but their route around the area is a major character of it, forming wide grassy avenues through the scrub and holding the promise of summer sun- traps and many a visiting butterfly. Beyond the scrub are other, more watery, habitats - a stretch of open water called Pitseahall Fleet, muddy creeks and saltings. The saltings on the south-west, west and north-west sides of the park are somewhat bleak and wind- swept - an unfortunate factor which causes unwelcome invasions of litter from the rubbish tip beyond. Within a year, however, the tip will be finished and reclaimed for the park - approximately doubling its size - then the clean-up operation can begin and the disturbing squeak of polystyrene and crack of plastic bottle underfoot will be removed. On the opposite side of the park is a more pleasant aspect: the Fleet. It is overlooked by a small bird-watching hide (open in the summer) and kingfishers, for example, have been spotted. Walking on from the Fleet, the pathway leads to another area of saltings and mudflats, covered by the tide for only about two to three hours each day and bearing a jumble of evidence of passing waders and mammals - large and small. There is a pleasant sound like that of a waterfall or fast-flowing stream nearby, but the origin of the sound will be found by looking up - to those huge pylons striding above. Looking up also brings to view the horizon, bedecked with the Shellhaven, Coryton and Corringham refinery and Cleanaway's waste disposal site.
