(PHOTO: PAUL GORIUP) ■ THE UNITED KINGDOM GENERAL INTRODUCTION given the differences in selection criteria. Though IBA boundaries are often the same as SPA or Ramsar Site boundaries (where relevant), The United Kingdom comprises Great Britain (England, Scotland this is not always the case. Many of the 61 sites added since the 1992 and Wales) and Northern Ireland, covering over 244,000 km2. It is inventory qualify because they hold important populations of species a densely populated and industrialized country, with diverse of European conservation concern. Since some of these species are landscapes, over 85% of which are used for agriculture or forestry. not yet identified in legislation for special protection, the Maritime influences are important, and the climate is warmer and corresponding sites may have no designation status at all. wetter than at the same latitudes in central or eastern Europe. Separate overviews are presented for the Channel Islands (p. 815) The United Kingdom has 287 Important Bird Areas (IBAs) which and for the Isle of Man (p. 817); data for these sites are not included cover more than 31,000 km2, representing over 12% of its surface within this UK overview text or the accompanying tables and figures. area (Table 1, Map 1). Of these, 80 are in England (covering over 9,000 km2), 17 are in Northern Ireland (over 1,900 km2), 173 are in Scotland (over 18,000 km2) and 17 are in Wales (over 2,000 km2). ORNITHOLOGICAL IMPORTANCE The 1989 inventory of IBAs in Europe (Grimmett and Jones 1989) identified 261 IBAs in the United Kingdom. Of these, 239 One hundred and two species of European conservation concern are represented here, some with boundary amendments and many (SPECs) regularly breed in the UK (Tucker and Heath 1994). Among as combined sites (for details see Table 1). Seventy-six IBAs have these, Crex crex is globally threatened, Haliaeetus albicilla is near- been newly identified since the 1989 inventory. threatened and Loxia scotica is endemic. Fifty of these SPECs have In 1992, an IBA inventory covering the UK, Channel Islands an unfavourable conservation status in Europe. Seven species classed and Isle of Man was published (Pritchard et al. 1992), a joint as SPECs on the basis of their winter populations occur during winter publication between the RSPB, the Joint Nature Conservation or on passage in the UK, and four of these have an unfavourable Committee and the Statutory Conservation Agencies: the conservation status in Europe.

The IBAs corresponded with the list of designated and A total of 147 IBAs in the UK qualify under one or more ‘A’ criteria; proposed Special Protection Areas and Ramsar Sites as published a further 82 qualify under B (but not A) criteria. Twenty-one sites in Hansard (17 July 1991 columns 203–208 and 219–224 and 18 July qualify because they contain important populations of a species of 1991 columns 256–257). This latest review is based on the 1992 global conservation concern (Table 2). inventory (itself based on that of 1989), with 232 of the 239 UK sites A high proportion of UK IBAs are important for wintering and in the 1992 inventory represented here in some way, either as passage waterbirds (Table 3). One hundred and forty-nine sites identical, merged, amended or split sites. Despite this, the IBAs regularly support over 20,000 wintering or passage waterbirds or documented here differ somewhat from the 1992 inventory, with more than 1% of the biogeographic or flyway population of a IBAs defined on their ornithological interest, irrespective of waterbird species (i.e. meeting criteria A4i, A4iii or B1i).
