Project summary

Edit project overview to modify the project summary.


Break out concrete wall on the nature reserve side of the river and re-grade the river bank to provide a wide shelf or berm. This berm will be inundated by water several times a year, thus restoring a strip of wet meadowland. Allow more natural fluvial geomorphological processes to occur and increase habitat. (See attached 3x Drawings at end of this form). The small nature reserve, owned by Lewisham Council, lies adjacent to the Quaggy and once formed part of an extensive water meadows system. Sadly, the river has been realigned and set in concrete. Though part of the old natural river channel passes through the nature reserve, it is dry and the site has lost its wetland characteristics. Enhancement would improve the biodiversity and interest of the nature reserve, reconnect river with ground and create a strip of wetland meadow.
