The marshes cover over 100 acres (0.40 km2) and became part of the Lee Valley Park[1] in 1972.
They contain a variety of plant communities typical of a former flood plain location, such as a range of neutral grassland types, sedge marsh, reed swamp, sallow scrub and areas of tall herb vegetation.
Between the 1860s and 1930 a range of facilities including tennis courts and swimming were available but after World War II between 1946 and 1960 the area was used for gravel extraction and landfill.
In the late 19th century the Wild Marsh East was bisected when the River Lea was diverted to accommodate the construction of some of the Lee Valley Reservoir Chain.
