Dublin Bay is designated as a Special Protection Area (SPA) based on the wintering waterbirds that it supports. It is internationally important for Light-bellied Brent Goose, Knot, Black-tailed Godwit and Bar-tailed Godwit, and supports nationally important numbers of a further 18 species.

Furthermore the site is located in close proximity to other internationally important waterbird sites, namely Baldoyle Bay, Broadmeadow Estuary and Rogerstown Estuary in Dublin and the Murrough Wetland Complex further south in Wicklow. Anecdotal reports have suggested regular movements of waterbirds between these sites in winter, but until now, no efforts have been made to quantify the extent of these movements.
