Dublin Bay is an internationally important feeding and roosting area for ducks, geese and waders, and probably holds the highest concentration of wintering waterfowl of an Irish estuary.

As part of the Dublin Bay area, Booterstown Marsh is an essential refuelling and resting spot for migrating birds and provides three main habitats ranging from freshwater to saltwater( Moorhen, Reed Bunting, Sedge Warbler, Teal, Snipe, Lapwing, Oystercatcher, Redshank, Dunlin, and Brent Geese).

Puccinellia fasiculata occurs in the marsh - it is one of only 68 plant species protected, along with its habitat, under the Wildlife Act (Flora Protection Order of 1987).
