Walthamstow Marshes SSSI

About this location

Walthamstow Marshes is one of the last substantial remnants of semi-natural floodplain habitat in Greater London. Its plant communities include neutral grassland, sedge marsh, reed swamp, sallow scrub and tall-herb vegetation, preserving a surprisingly varied wetland landscape within the heavily urbanised Lea Valley.

The marshes are designated as a Site of Special Scientific Interest for this surviving floodplain vegetation and the uncommon plants and insects associated with it. They also form an important ecological link through the wider Lea Valley, connecting the reservoirs and wetlands to the north with Hackney Marshes and other green spaces further south.
