When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|6230 Species-rich Nardus grasslands, on silicious substrates in mountain areas (and submountain areas in Continental Europe) * Priority feature|
|Ardmeanach is one of five sites representing the range of low-altitude sub-types of species-rich Nardus grasslands on the oceanic west coast of Scotland. Ardmeanach is one of the most westerly and maritime of the sites selected. The species-rich Nardus grasslands occur extensively as short swards on a large basalt escarpment. The most extensive community represented is CG10 Festuca ovina – Agrostis capillaris – Thymus praecox grassland, but on more northerly-facing slopes this is replaced by CG11 Festuca ovina – Agrostis capillaris – Alchemilla alpina grassland. A range of sub-types of these two communities is represented. Sub-maritime variants of the habitat are developed on the lower parts of the escarpment, with the maritime species sea plantain Plantago maritima, buck’s-horn plantain Plantago coronopus and wild carrot Daucus carota. Dry and wetter sub-types are both represented. There is a high plant diversity, including lowland species, such as common centaury Centaurium erythraea, fragrant agrimony Agrimonia procera, red clover Trifolium pratense and false-brome Brachypodium sylvaticum, as well as upland, northern species, such as globeflower Trollius europaeus, the lady’s-mantle Alchemilla glabra and northern bedstraw Galium boreale. There are transitions to maritime grassland and species-rich dry Calluna heath.|
|6430 Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels|
|The upper base-rich basalt cliffs of Ardmeanach support well-developed examples of hydrophilous tall herb fringe communities in the relatively mild south-west of Scotland. The stands represent some of the best examples known on basalt crags and in south-west Scotland generally. The flora is unusual in the association of contrasting geographical elements, such as the southern Atlantic liverwort Marchesinia mackaii together with northern and arctic-alpine species such as northern bedstraw Galium boreale, moss campion Silene acaulis and alpine lady’s-mantle Alchemilla alpina. Characteristic species include globe-flower Trollius europaeus, wild angelica Angelica sylvestris and lady’s-mantle Alchemilla glabra. Unusually, woodland species such as dog’s mercury Mercurialis perennis and false brome Brachypodium sylvaticum occur, perhaps because of the low altitude of the cliffs.|
