Floodplain Grazing Marsh Sites are found in the floodplain areas of the rivers Dearne and Dove and some of their tributaries.
There are at least 15 important sites of this type in Barnsley, all found in the Dearne Valley. The RSPB manage several of these important sites and the Garganey Trust manage two others.
Wombwell Ings is probably the most significant Floodplain Grazing Marsh in the Barnsley area. Other sites include: Broomhill Flash, Parkhill Brickworks, Edderthorpe Ings, Wath Ings, Doveside, Old Moor and Wath Ings, Adwick washlands, Carlton Marsh and Wilthorpe Marsh. RSPB Old Moor includes new and modified areas of this type.

They are selected as LWS because of the wintering and breeding wildfowl and waders that such grassland supports.
The LWS vegetation criteria for floodplain grazing marsh habitat are that it should be ≥0.5ha in size and have 18 or more species from a list of 90 grassland indicator plants, including grasses and sedges.
