Abstract

  • 1The use of redeveloped docks for the conservation of lagoonal communities is considered with particular reference to the South Docks in Liverpool.
  • 2Redevelopment of the previously derelict South Docks since 1981 has created a semi-enclosed, brackish body of water by dredging of dock basins that were filled with silt. The development of biological communities on the walls and in the sediments of these docks has been studied.
  • 3A reasonably diverse flora and fauna was established on the walls within approximately six years, but a persistent sediment-dwelling community has not yet developed.
  • 4Over 90 species of macroflora and macrofauna have been recorded from the South Docks to date. Three of these species are considered to be lagoonal specialists.
  • 5Considerations for the management of docks as a resource in the conservation of lagoonal communities are discussed.
