The Severn Estuary is an important site for migrating and wintering waders. The estuary is a Ramsa site and also effected by SAC, SSSI, and SPA designated sites.
The second highest tide in the world means that spring high tides [those over 12M] push roosting waders to areas where they are more exposed to disturbance. Redshank, Dunlin, Culew, Snipe, Little Egret, Grey Plover and Black Tailed Godwit being the main species.
Any disturbance to spring high tide roosts [SHTRs] especially in hard weather can have serious effects on the birds well-being including increased mortality and migration failure.
As a responsible wildfowling association we take seriously all conservation measures, this includes awareness of SHTRs. All our members are made aware of the significance of SHTRs and have to attend walks to identify them. They are required to adhere to the BASC code for good wildfowling practice, https://basc.org.uk/cop/wildfowling/ as well as other measures and guidance when wildfowling on or near the foreshore.
