Climate exposure

This is about exposure to a nationwide pressure this habitat type carries — not a verdict on this site's own management.

Coastal

Coastal habitats are exposed to sea-level rise and storm erosion. Where hard sea defences sit behind them, there's nowhere landward to retreat to — a squeeze that keeps compressing the habitat no matter how well it's managed.

Description

Description Bryn Alyn is of special interest for its range of limestone (calcicolous) grassland as well as its transitions from limestone and neutral to acidic (calcifugous) grassland, limestone heath, and its rock and scree habitats. Bryn Alyn is a steep sided hill located some 5 km from Mold, in the south-eastern part of the Clwydian Range, rising to an altitude of 408m. The site is divided into several large enclosures, the majority of which are sheep grazed. Rock outcrops, limestone ridges and sheer cliff faces are frequent throughout the site and there are also areas of limestone pavement, the largest of which is located towards the summit of the hill. The bedrock is Carboniferous Limestone throughout, with the thinner soils derived from this. Blocks of scree occur in a few places within the site, particularly in association with the birch dominated woodland along the northern flank of the site. Some areas within the site are covered with glacial drift producing a more acidic soil. The site is free draining and can be rather drought prone where the soils are thinnest. The limestone pavement supports a rich flora including harts tongue fern Asplenium scolopendrium, meadow-rue Thalictrum minus, herb-robert Geranium robertianum, dog’s mercury Mercurialis perennis and hawthorn Crataegus monogyna. On the rockiest, thinnest and most drought prone soils there are areas of sheep’s-fescue Festuca ovina, carline thistle Carlina vulgaris grassland. The turf is short, open and dominated by sheep’s-fescue. Other grasses including crested hair-grass Koeleria macrantha and quaking-grass Briza media frequently occur, with characteristic calcicolous herbs such as common rock-rose Helianthemum nummularium, salad burnet Poterium sanguisorba, wild thyme Thymus polytrichus, common bird’s-foot-trefoil Lotus corniculatus, carline thistle, small scabious Scabiosa columbaria and mouse-ear hawkweed Picris officinarum. Various bryophytes form a major component of the turf, particularly prominent species includes Hypnum cupressiforme and Ctenidium molluscum. The Nationally Scarce lichen Placidiopsis custnani also occurs within this grassland type. The less rocky areas with deeper soils support sheep’s fescue and meadow oat grass Avenula pratensis grassland. The turf is typically dominated by grasses, particularly frequent and abundant species includes sheep’s-fescue, crested hair grass, common bent Agrostis capillaris, heath-grass Danthonia decumbens, red fescue Festuca rubra and quaking grass. Associated sedges include glaucous sedge Carex flacca and spring-sedge Carex caryophyllea with a variety of forbs including harebell Campanula rotundifolia and lady’s bedstraw Galium verum. There is also a diverse bryophyte layer associated with this calcicolous grassland. In certain areas of the site stands of the limestone grassland are characterised by typical calcicoles in addition to species which generally favour more circum-neutral soils such as common knapweed Centaurea nigra, devil’s-bit scabious Succisa pratensis and rough hawkbit Leontodon hispidus. On areas which have become modified by agricultural improvement crested dog’s-tail Cynosurus cristatus and Yorkshire-fog Holcus lanatus predominate together with musk thistle Carduus nutans, spear thistle Cirsium vulgare and white clover Trifolium repens. The Nationally Scarce lichen Peltigera leucophlebia is also found on site. There are also localised stands of sheep’s-fescue, common bent and wild thyme grassland. This particular grassland occurs as a transitional zone between the calcareous sheep’s fescue and meadow oat grass grassland and the more acidic grassland types. This grassland type is of interest as it contains species which are indicative of both calcareous and acidic conditions. On the moister, more base poor soils the mat-grass Nardus stricta, heath bedstraw Galium saxatile grassland occurs. This acid grassland is dominated by mat grass but there is also generally abundant bilberry Vaccinium myrtillus and heather Calluna vulgaris as well as an abundance of bryophytes such as Hylocomium splendens, Rhytidiadelphus squarrosus and Pseudoscleropodium purum. Closely related to this type of grassland is the sheep’s-fescue, common bent Agrostis capillaris and heath bedstraw Galium saxatile acid grassland. This is found on slightly drier soils and is dominated by grass species such as common bent, sheep’s-fescue, red fescue and sweet vernal-grass Anthoxanthum odoratum. The main characteristic herbs include tormentil Potentilla erecta, heath bedstraw and field wood-rush Luzula campestris. There are various forms of this grassland, ranging from species-poor semi-improved swards through to those which have undergone very little modification such as those swards supporting frequent bird’s foot trefoil and bitter-vetch Lathyrus linifolius. On the more gently sloping and flatter ground there are stands of crested dog’s tail and common knapweed grassland. This neutral grassland type is characterised by herbs such as hoary plantain Plantago media, rough hawkbit, bulbous buttercup Ranunculus bulbosus, birds-foot trefoil and cowslip Primula veris. On the drier deeper soils there are small stands of heather and western gorse Ulex gallii heath, which tends to occur as a mosaic with the various types of calcareous and acidic grassland. There are a variety of heath vegetation types, ranging from stands containing few species other than the dominants, through stands where calcifugous species such as heath grass, heath milkwort Polygala serpyllifolia and bilberry are associates, to stands supporting calcicolous species such as lady’s bedstraw, common rockrose, glaucous sedge and salad burnet. This calcicolous heath comprises the largest element of the dry heath on the site. On the lower north and north-west facing slopes of the site there is a stand of semi-natural broadleaved woodland. The canopy is very open and is dominated by silver birch Betula pendula with occasional rowan Sorbus aucuparia. The shrub layer is relatively sparse or absent and comprises scattered hawthorn, hazel Corylus avellana and silver birch saplings. The field layer is dominated by a mixture of grasses including tufted hair-grass Deschampsia cespitosa, common bent, red fescue and sweet vernal-grass. Associated herbs includes wood-sorrel Oxalis acetosella, barren strawberry Potentilla sterilis and common dog-violet Viola riviniana. The areas of limestone scree supports a variety of species including robust bryophytes such as Neckera crispa and Hylocomium splendens. The Nationally Scarce limestone fern Gymnocarpium robertianum has also been recorded at various locations throughout the site, principally on the shaded northern outcrops. On the more accessible and flatter areas of the site agricultural modifications have produced semi-improved and improved areas of grassland. There are also considerable stands of bracken. Remarks: The site lies within the Clwydian Range AONB
