3. Rails
Moorhens Gallinula chloropus are widely distributed
across Britain and Ireland (other than in north-west Scotland).
Britain is particular important in terms of the European
conservation of this species. Indeed, Britain and Ireland hold 35%
of the European population, with smaller numbers also in France,
The Netherlands and Spain (Hagemeijer & Blair 1997). The range
(and numbers) of Moorhen declined between 1968–1972 and 1988–1991
(Gibbons et al. 1993). There are no known internationally
important concentrations in the UK, though Moorhens occur
incidentally in most wetland SPAs classified for other waterbirds.
Water Rails Rallus aquaticus are locally distributed
across the UK. Britain and Ireland lie on the edge of the European
range and together hold only a small proportion of the European
population (c. 1.5%). Although traditional sites are used,
there are no known concentrations of European importance, but
census data are very poor.
