Project summary

Edit project overview to modify the project summary.

Although initially designed as a flood storage area to aid sustainable drainage systems, this area of land provides rare wetland habitat within an urban London setting. The wetland includes areas of reedbed which is scarce and under threat within the UK, and listed as a priority habitat within the UK’s Biodiversity Action Plan. The land had previously been used for educational purposes by the adjacent school, but on-site management has declined resulting in a lack of school usage and reduced habitat value. Key habitats that would benefit from restoration include:

  • Willow carr;
  • Reed bed;
  • Open water / marginal communities.

The project has provided much needed management to the site to restore the wetland habitats and again provide a safe educational resource for local schools. The project has developed an ongoing site management plan to ensure the achieved improvements are maintained.

The key partner in this project, the London Borough of Sutton, are to propose the site for designation as a Local Nature Reserve. Project objectives: Improve the habitat and community value of Anton Crescent Wetland; To produce a long term management plan for site; To present site for designation as Local Nature Reserve under the National Parks and Access to the Countryside Act 1949.

Key activites: Manage reedbed and maintain are of open water; Manage willow trees for wildlife and maintain flood storage capacity; Improve structure and biodiversity of meadow; Increase public awareness and enjoyment of site, generating local interest and provide educational resource.
