Cardiff Bay Wetlands Reserve

The reserve is a biodiversity hot-spot within Cardiff Bay. The reedbed and other aquatic plants, are very productive vegetation and a habitat for birds. Prior to the construction of the Cardiff Bay Barrage, it was made up of mudflats and salt marsh. (ref1) The site was chosen by Cardiff Harbour Authority to create a new environment and compensate in part for the loss of the mudflats which were submerged after completion of the Cardiff Bay Barrage. Floating timber structures serve as breeding areas for birds, an underwater bund prevents wave erosion, and a boom keeps out waterborne debris (ref5)

Urban setting

  • Blue areas
    • Wetland/bog/fen/marsh

Key challenges

  • Green space, habitats and biodiversity (SDG 15)
  • Regeneration, land-use and urban development

Main beneficiaries

  • Local government/Municipality
  • Citizens or community groups
Project objectives
1. Wetlands created to provide an important habitat for many species (ref 1) 2. to compensate in part for the loss of the mudflats which were submerged after completion of the Cardiff Bay Barrage. (ref 5) 3. The target habitats for the Cardiff Bay Wetlands Reserve, as set out in the ‘Cardiff Bay Wetlands Management Proposals’ are: • Reed beds • Tall-herb fen • Ditch habitats • Freshwater ‘open’ lagoons. (ref 2)
Implementation activities
The wetlands were created when the barrage was completed and the previous saline mudflats were transformed into freshwater marshland and a 400 acre lake. (ref 7)
