Phytosociological data were collected to describe the terrestrial lichen and bryophyte vegetation of rock or saxicolous habitats within 14 Special Areas of Conservation (SAC) within upland Britain, with special reference to four saxicolous habitats listed in Annex I of the EU Habitats Directive. Natural Resources Wales (NRW) holds the Welsh data as well as copies of the project report. The work aimed to improve our knowledge of the lichen and bryophyte communities of rock habitats in upland Great Britain, with particular regard to certain habitats, which have importance in nature conservation legislation. The work had the following main objectives: 1. To describe the lower plant assemblages of Annex I rock habitats in selected sites, which are Special Areas of Conservation (SACs). 2. To provide a preliminary classification of the lower plant communities of rock habitats in upland Britain (excluding freshwater habitats). These objectives were achieved by extensive sampling of rock habitats, using phytosociological methods, within selected SACs. Those visited were, in Wales: Brecon Beacons, Cadair Idris, Eryri and Berwyn and South Clwyd Mountains.

All types of saxicolous vegetation were regarded as suitable for sampling, except freshwater habitats and stands dominated by vascular plants. Extensive sampling of rock habitats was carried out using standard phytosociological methods as outlined by Rodwell (1991-2000). Data collected were analysed by two-way indicator species analysis implemented by the computer programme TWINSPAN. 14 SACs across Britain were surveyed and a number of additional samples were collected from three additional sites for incorporation into the analysis.
