 Site Description Three blocks of arable fields. The fields have a number of different owners which includes the National Trust and are managed under different forms some in arable cultivation some in fallow and some as grassland.

 Botanical Significance The site is an Important Arable Plant Area of European importance. Fumitory Fumaria species, subspecies and variants are prominent alongside a range of other uncommon taxa, many of which are anciently-naturalised and occur here at the edge of their range. More than 60 species of wild plants of arable fields have been recorded from this site. There are good populations of the nationally scarce small-flowered catchfly Silene gallica and of the regionally rare species, sharp-leaved fluellen Kickxia elatine, weasel’s snout Misopates orontium, annual knawel Scleranthus annuus, dwarf spurge Euphorbia exigua, small-flowered buttercup Ranunculus parviflorus and cornfield knotgrass Polygonum rurivagum.

 General Habitat Description The site incorporates three blocks of arable fields, located to the east of Foel y Mwnt and south-west of Mwnt towards Cardigan Island, at altitudes between 20 and 60 m. These fields abut onto the north-facing coastal cliffs and slopes and their underling clay soils are replaced towards the seaward margin by light, shale-rich soils or locally by bedrock composed of Lower Palaeozoic (Ordovician) mudstones and shales. Caeau Crug Bychan, Ty Gwyn a Llwyn Ysgaw support a species-rich wild plant community (SSSI citation)
