Project summary

Edit project overview to modify the project summary.


Previous site use/issues

• Terrestrial habitat with rank grassland and species poor scrubland.

• Plot of adjacent to Barking Creek, accessible by informal and underused riverside footpath.

• Blind spots within site (formed by sections of redundant fencing) lead to a raised ‘fear of crime’.

• Riverside footpath not suitable for wheelchairs.

• Concrete flood defence in poor condition needing replacing.

Enhancements

• Retreat and renewal of flood defences adapting to climate change by creating increased flood storage capacity and improved riverside and intertidal habitat. Reed bunting and sand martins have been seen in this area.

• Sand martin nesting tubes.

• Improved footpath, suitable for wheelchairs.

• Blind spots remove and the site opened up although reeds allowed establish to help protect the wildlife on the river.
