Bull Island, 2007
A small island built up over 200 years as a result of the construction of the north harbour wall of Dublin Port, it has an adjoining foreshore of sandy beaches, dunes, saltmarshes and mudflats. It is connected to the land by a wooden bridge and a more recently constructed causeway. The site is unique in Ireland because it supports well-developed saltmarsh and dune systems displaying all stages of development from the earliest phase of colonisation to full maturity. Its location as a UNESCO Biosphere reserve within a capital city is also unique and it is classified as a Wetland of International importance under the Ramsar Convention.
