North Wirral foreshore
North Wirral Foreshore is located between the outer Dee and Mersey Estuaries. This site is an area of intertidal sand and mudflats and embryonic saltmarsh, which is of considerable importance as a feeding and roosting site for passage and wintering flocks of waders, wildfowl, terns and gulls.
The embryonic mixed saltmarsh is formed principally from Common Saltmarsh-grass (Puccinellia maritima) and Glasswort (Salicornia europaea), together with some Common Cord-grass (Spartina anglica).
Whilst North Wirral Foreshore is not comparable with either the Dee Estuary or the Mersey Estuary in terms of the numbers and diversity of passage and wintering birds it is still of great value for the large populations of Knot, Dunlin and Bar-tailed Godwit it supports.
The wintering populations of Knot (20,000+), Bar-tailed Godwit (2,000+) and Dunlin (10,000+) are the most significant because their numbers regularly exceed 1% of the total British and Irish wintering populations. Redshank (1,000+) and Turnstone (500+) feed on the rocky shore at Perch Rock and on the rocky sea walls. Oystercatcher (500+), Curlew, Grey Plover and Black-tailed Godwit are other waders which regularly roost here in relatively high numbers.
Small populations of wildfowl, including Common Scoter, Scaup and Goldeneye, Red-throated Divers and Great Crested Grebes also frequently winter on this site.
