18 200 bird species a year seen in the Lee Valley. The 23 miles of river between Ware, Hertford- shire and Stratford in London form the Lee Valley Park area. The park authority was established in 1967 to meet increasing public leisure needs. Many sports and activities are catered for within the park, including sailing, camping, ice skating and go-kart racing. In the last few years the authority has begun to provide bird hides around the Fishers Green area (which are only open to the public at weekends) and the Ranger service provides a varied programme of guided walks. The habitats available within the Park include river, reservoir, flooded gravel pits, sewage works, scrub, small areas of woodland, marsh, farmland and grassland. All this provides the basis for the bird activity. The R.S.P.B. have a reserve at Rye House Marsh where terns breed in summer and a Bittern often over-winters. The Thames Water Authority, on written application and payment, issue permits to view some reservoirs and sewage farms in the valley which again produce many marvellous species records such as Divers and Grebes in winter and Osprey on passage. Although the Lee Valley may not be the most attractive area of Essex/Herts, its resident breeding, passage and wintering bird records are impressive by even national standards. Why not see for yourself in '88? Further information about the Park and ranger service is available from:
