Rogerstown Estuary

Rogerstown Estuary is an estuary in Ireland. It is situated just north of the Donabate Portrane peninsula, and also south of Rush, on Ireland's east coast about 25 km north of Dublin. The estuary is made up of saltwater marshes, raised salt marsh, moist meadows and riverine shallows and creeks. It covers a place of 3.63 km2 and is split by means of a causeway and bridge built inside the 1840s to hold the primary Dublin–Belfast railway line.

It is internationally identified as one of the most vital east coast web sites and is critical for wintering wildfowl and waders and birds on passage. Birds come to the estuary from the Arctic. It supports an across the world crucial populace of Brent Geese and a similarly 14 species in numbers of national importance. The site is a statutory Nature Reserve and a candidate Special Area of Conservation below the E.U. Habitats Directive. The estuary's mouth separates the beaches of Portrane and Rush; and the mouth is so narrow, it is theorized that someone could be able to pass from Rush to Portrane at slow walking pace, inside a time span of much less than a minute, if there was no water.
