Important Bird Areas in Europe – Faroe Islands ■ FAROE ISLANDS Puffin Fratercula arctica, an important species at IBAs in the Faroe Islands. (PHOTO: JÓHANN ÓLI HILMARSSON) GENERAL INTRODUCTION The data and descriptions presented in this chapter are taken largely from the previous pan-European IBA inventory (Grimmett The Faroe Islands (Føroyar) are a self-governing region of the and Jones 1989). Kingdom of Denmark. They comprise a group of 18 islands in the north-east Atlantic at about 62°N and 7°W. The total land area is 1,399 km2 and the topography is dominated by hills extending to ORNITHOLOGICAL IMPORTANCE 82 m in height. The human population is 44,817 (in 1998) with an average population density of 32 persons per km2. In all, more than 250 bird species have been recorded in the islands, Nineteen Important Bird Areas (IBAs) are identified, covering but most of these are rare or irregular visitors, with less than 50 an area of 67 km2 (Table 1, Map 1). species breeding regularly (Bloch et al. 1996), of which 35 are species Table 1.

Important Bird Areas in the Faroe Islands that support E. Mortensen and B. Olsen have estimated the sizes of the other important numbers of one or more congregatory species (i.e. populations. The most numerous species are Fulmarus glacialis meeting criteria A4 and/or B1). IBAs meeting both criteria A4 and (600,000 pairs), Fratercula arctica (550,000 pairs), Hydrobates B1 for the species are shown in bold. IBAs meeting only criterion pelagicus (250,000 pairs), Rissa tridactyla (230,000 pairs) and Uria B1 for the species concerned, and not A4, are shown in normal aalge (175,000 pairs). type.

Tourism is a relatively new trade in the Faroes and there is no documentation of it having serious negative effects on the birds, although there is some cause for concern. The seabird cliffs are of European conservation concern (SPECs; Tucker and Heath very popular and tourism may become a serious threat if not 1994). managed to minimize the effect on the birds. Inland, species diversity is low (Bloch and Sørensen 1984), and the only species of interest are Numenius phaeopus, the c.210 pairs of Stercorarius skua (which has a limited global range), and 10–15 PROTECTION STATUS pairs of Gavia stellata, breeding on some lakes.
