Conservation Floodplain Grazing Marsh sites are a priority in the Dearne Valley of Barnsley; some are being managed to promote wildlife and more can be done.


Factors causing loss or decline

Legal protection

Currently no Floodplain Grazing Marsh sites in Barnsley have legal protection as a SSSI.


Six sites are lLocal Wildlife Sites (LWS) with a presumption against development or change of use when planning consent is required.


One has Local Nature Reserve status and some are managed as nature reserves without this designation.


Specific wildlife species are protected under the Wildlife and Countryside Act. This includes intentionally or recklessly disturbing birds at, on or near an ‘active’ nest. 


Many of the sites fall in statutory washlands for which the Environment Agency has regulatory responsibility.
