North Bull Island. 06/09/88; Dublin; 1,436 ha; 53°22'N 006°08'W. Biosphere Reserve; Special Protection Area EC Directive; Nature Reserve. A small island built up over 200 years against a harbour wall and the adjoining foreshore of sandy beaches, saltmarshes and mudflats. 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 colonization to full maturity. The site supports five protected or threatened plant species and nationally important populations of three insect species. The area is important for nesting Sterna albifrons (80 pairs, or about 30% of the Irish population) and for numerous species of wintering waterbirds. Human activities include bait digging. Ramsar site no. 406.
