Booterstown Marsh, a Nature Reserve, is located in Booterstown, County Dublin, between the coastal railway line and the Rock Road. It is an area of salt marsh and muds, with brackish water. It includes the only salt marsh, and the only bird sanctuary, in south Dublin Bay.[1] It lies just outside the boundary of Dublin city, and just north of Booterstown DART station and its car park.
The marsh belongs to the residual Pembroke Estate, and An Taisce administer it, having acquired a lease in 1970-1971 and having designated it a bird sanctuary.[1] It is part of both a proposed Natural Heritage Area (NHA) and a proposed Special Area of Conservation (SAC),[1] and of the South Dublin Bay and River Tolka Estuary Special Protection Area (SPA).[2]
