Annex I habitats that are a primary reason for selection of this site

  • Caenlochan is the most continental hill in the SAC series for Alpine and Boreal heaths, and shows proportionately the most extensive development of lichen-rich heath and the least development of more oceanic kinds of heath. H19 Vaccinium myrtillusCladonia arbuscula heath is extensive and well-developed, with abundant lichen cover. Characteristic species such as the lichen Cetraria nivalis and trailing azalea Loiseleuria procumbens are widespread. Other communities represented are H13 Calluna vulgarisCladonia arbuscula, H20 Vaccinium myrtillusRacomitrium lanuginosum and H22 Vaccinium myrtillusRubus chamaemorus heaths.

  • Sub-Arctic Salix spp. scrub is relatively frequent at Caenlochan, growing to a high altitude on highly to moderately calcareous schist. Corrie Sharroch holds the largest single patch (around 0.5 ha) of W20 Salix lapponumLuzula sylvatica scrub remaining in the UK. The scrub is also found spread across a larger area of crag and steep rocky slope than on any other site in the UK. The most abundant species, and generally the dominant one, is downy willow Salix lapponum, which probably occurs in larger numbers here than on any other site in the UK. There is a relatively large patch of scrub dominated by woolly willow S. lanata, and the site may hold the second-largest population of this species in the UK. Whortle-leaved willow S. myrsinites and net-leaved willow S. reticulata are also present. The associated habitat is mainly 6430 Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels.

  • Caenlochan in north-east Scotland represents natural, open Calaminarian grasslands over serpentine debris, occurring at about 850870 m altitude on Meikle Kilrannoch, the highest representation of the habitat in the UK. The site is notable for the large population of the rare alpine catchfly Lychnis alpina, which occurs at only one other locality in the UK (the other station being in the English Lake District). Other characteristic plants of the debris include thrift Armeria maritima, mossy cyphel Minuartia sedoides and scurvygrass Cochlearia sp. This is the only known site for the Scottish endemic subspecies of common mouse-ear Cerastium fontanum ssp. scoticum.

  • Caenlochan is representative of Siliceous alpine and boreal grasslands on high hills in the eastern Highlands. This is the most continental site in the series and is unique because it is the only site where the predominant community of the summit plateau is U8 Carex bigelowiiPolytrichum alpinum sedge-heath rather than the more widely predominant U10 Carex bigelowiiRacomitrium lanuginosum moss-heath. The extent of CarexPolytrichum sedge-heath is the largest of any site in the UK. The more characteristically oceanic CarexRacomitrium moss-heath is represented by some good stands but is not so extensive. U7 Nardus strictaCarex bigelowii grass-heath is also well-represented. There is a moderately large representation of late-lie snow-beds of U11 Polytrichum sexangulareKiaeria starkei snow-bed and U12 Salix herbaceaRacomitrium heterostichum snow-bed, while some small examples of U14 Alchemilla alpinaSibbaldia procumbens dwarf-herb snow-bed are also present on shelves on high ground.

  • Caenlochan is the most easterly site selected and is representative of hydrophilous tall herb fringe communities in the eastern Highlands. The habitat type is widely-developed across the site and is found on ledges of calcareous and more acid schists with a wide altitudinal range, including very high altitudes (550870 m). Caenlochan is considered to have the greatest extent of this habitat type in the UK. There is an extremely diverse and well-developed montane flora containing a range of characteristic species, such as roseroot Sedum rosea, red campion Silene dioica, water avens Geum rivale, globeflower Trollius europaeus and wood crane’s-bill Geranium sylvaticum. Rarer species include black alpine-sedge Carex atrata, alpine gentian Gentiana nivalis, alpine fleabane Erigeron borealis, alpine mouse-ear Cerastium alpinum and alpine cinquefoil Potentilla crantzii. A very rare species that occurs on more acid ledges and is not represented on any other site in the series is alpine blue-sow-thistle Cicerbita alpina. The ledges at lower altitude have woodland species, such as wood anemone Anemone nemorosa and dog’s mercury Mercurialis perennis, which are usually rare in the habitat type.

  • 7130 Blanket bogs (* if active bog)  * Priority feature

    Caenlochan contains extensive areas of high altitude Blanket bogs representative of the eastern Highlands of Scotland. The blanket bog belongs to the M19 Calluna vulgarisEriophorum vaginatum blanket mire community and is extensive between 700 m and 900 m altitude. Above about 800 m, where the bogs occupy an extensive high plateau, heather Calluna vulgaris is replaced by cowberry Vaccinium vitis-idaea and the montane dwarf-shrubs crowberry Empetrum nigrum ssp. hermaphroditum and bog bilberry Vaccinium uliginosum. These montane blanket bogs show floristic affinities with mountain bogs in Scandinavia.

  • Caenlochan is one of two sites in the eastern Highlands representing base-rich mires at moderately high to high altitude. These mires are frequent within the site and have high species diversity. There is a well-developed community structure and the rarer species occur frequently. Open flushes of M11 Carex demissaSaxifraga aizoides mire and the closed M10 Carex dioicaPinguicula vulgaris mire are both widely-developed. Characteristic species include three-flowered rush Juncus triglumis, chestnut rush J. castaneus, alpine rush J. alpinoarticulatus, Scottish asphodel Tofieldia pusilla, and sheathed sedge Carex vaginata. Hair sedge C. capillaris, alpine bistort Persicaria vivipara and alpine meadow-rue Thalictrum alpinum are also present. An additional interest is the presence of an eastern outlier of the mainly western M12 Carex saxatilis mire.

  • Caenlochan is representative of communities on calcareous and calcshist screes at high altitude in the eastern Scottish Highlands. Although the habitat type is localised within the site, Caenlochan has a variety of different screes with an unusual flora. Fern-rich screes on calcareous-schist rocks support holly-fern Polystichum lonchitis, buckler-fern Dryopteris spp., roseroot Sedum rosea and mountain sorrel Oxyria digyna, while porphyritic screes have alpine penny-cress Thlaspi caerulescens and alpine speedwell Veronica alpina.

  • Caenlochan represents high-altitude Calcareous rocky slopes with chasmophytic vegetation in the eastern Highlands, on extensive outcrops of calcareous schists. The site has one of the most extensive and diverse high-altitude crevice habitats in the UK, with an abundance of characteristic high montane plant species. These include a number of rare species, such as mountain bladder-fern Cystopteris montana, alpine woodsia Woodsia alpina, rock sedge Carex rupestris, glaucous meadow-grass Poa glauca and hoary whitlowgrass Draba incana. The montane calcicole bryophyte flora is also outstanding and includes a number of species not present on other selected sites.
