Geology & landscape

Geological Period: Silurian

Description

Description This site is a good example of a sessile oakwood with closely spaced even-aged trees, developed on free draining Silurian (Tarannon and Llandovery) strata. The presence of streams adds diversity to the woodland habitat. The site displays well a ground flora typical of grazed upland oakwood. The wood is comparatively species-rich including, for example, opposite-leaved golden-saxifrage Chrysosplenium oppositifolium, bluebell Hyacinthoides non-scripta, yellow pimpernel Lysimachia nemorum, tormentil Potentilla erecta and common valerian Valeriana officinalis, but these are all sparsely represented and the ground layer is typically of bent and fescue grasses Agrostis and Festuca with bracken Pteridium aquilinum locally abundant and heather Calluna vulgaris and bilberry Vaccinium myrtillus common.
