Title: River catchment management plans : marsh dykes ecology survey : appraisal report
Author: National Rivers Authority Thames Region
Document Type: Monograph
Abstract:
A vegetation survey was carried out over the wetland habitats of the Marsh Dykes in summer/autumn 1990. This area comprises the foreshore, dykes and adjacent wetlands of Thamesmead, Erith, Belvedere and Crayford. The catchment is of high value in the context of the London Area and Erith and Crayford Marshes especially are of regional significance. In both of these areas, almost all main dykes and marshes examined were rated as critically important habitat. Thamesmead and Belvedere are more variable but both contain critically important habitats and illustrate how sites surrounded by built development can still retain significant wildlife populations. The objectives of this report are: a) To collate and review information on known areas of conservation importance-in -the Marsh Dykes Catchment; (b) To carry out river corridor field surveys on 17.8km of main river watercourse and associated floodplain (approx 90ha) and 55ha of tidal frontage; (c) To prepare reports detailing the results of the above investigations and to assess constraints and opportunities for enhancement associated with the water environment in the Marsh Dykes Catchment.
