Description

Description The Parish Field, Cae’r Rhedyn is of special interest for its species-rich neutral grassland. Some of this habitat has a particularly calcicolous nature. This is one of the rarest types of grassland in Wales, now mainly confined to a small number of sites in the Vale of Glamorgan, Monmouthshire and north-east Wales. By contrast, in other parts of this site, the soils are more acidic, and it is a particular characteristic of The Parish Field, Cae’r Rhedyn that calcicolous and acidic grasslands occur in an intricate mosaic. Associated habitats include small areas of scrub and overgrown hedgerows. The site consists of a single field above the village of Graig Penllyn, approximately 3 km north-west of Cowbridge, at an altitude of between 60 and 90m. The field has a south-westerly aspect, sloping towards a minor road that forms part of the SSSI boundary. The soils are free draining brown earths over Carboniferous limestone. The principal habitat at The Parish Field, Cae’r Rhedyn is the neutral grassland. This is characterised by grasses, such as common bent Agrostis capillaris, sweet vernal-grass Anthoxanthum odoratum, crested dog’s tail Cynosurus cristatus, red fescue Festuca rubra, and Yorkshire fog Holcus lanatus. Typical herb species include yarrow Achillea millefolium, common knapweed Centaurea nigra, rough hawkbit Leontodon hispidus and common bird’s-foot-trefoil Lotus corniculatus. Where the soil is lime-rich, these grassland plants are joined by lady’s bedstraw Galium verum, salad burnet Poterium sanguisorba, quaking grass Briza media, yellow oat grass Trisetum flavescens and downy oat grass Avenula pubescens. In other areas, where the ground is steepest, the soil has become leached, and plants preferring more acid soils occur, including devil’s-bit scabious Succisa pratensis, betony Betonica officinalis, burnet-saxifrage Pimpinella saxifraga and tormentil Potentilla erecta. Scarce or local species that have been recorded at The Parish Field, Cae’r Rhedyn include common rock-rose Helianthemum nummularium, moonwort Botrychium lunaria and crested hair-grass Koeleria macrantha. Remarks: The site supports the UK Biodiversity Action Plan (BAP) priority ‘lowland meadow’ habitat. The Parish Field, Cae’r Rhedyn is owned by the charity Allotments for the Labouring Poor, of which Penllyn Community Council is the official custodian.
