3. ECOLOGICAL INFORMATION
Back to top3.1 Habitat types present on the site and assessment for them
No habitat types are reported for the site
3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them
- Group: A = Amphibians, B = Birds, F = Fish, I = Invertebrates, M = Mammals, P = Plants, R = Reptiles
- S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
- NP: in case that a species is no longer present in the site enter: x (optional)
- Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
- Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
- Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
- Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

Other Site Characteristics
Bills Rocks are a group of three rocks lying close together approximately 10 south of Moyteoge Head (Achill Island). The islands are composed of metamorphic rock and are drift covered. They rise precipitously to a height of approximately 35 m. The two larger islands have flattish tops which are covered by swards of Armeria maritima. Rocky reefs surround the islands. The sea area to a distance of 500 m from the island is included for the benefit of the breeding auks. |
4.2 Quality and importance
The site supports nationally important population of Fratercula arctica (ca. 7.1% of the all-Ireland total). It also has a colony of Hydrobates pelagicus which is at least of regional importance. Other breeding seabird species are Fulmarus glacialis, Phalacrocorax aristotelis, Larus marinus, Rissa tridactyla and Alca torda. The site is an excellent example of an isolated and highly exposed seabird colony. |
