Geology & landscape

Rock Type: Chalk

Description

Area, 26.8 hectares 66.2 ac Description The series of dales west of Raisthorpe supports chalk grassland representative of several of the types found on the Yorkshire Wolds. The dale sides are, in the main, close grazed and free from scrub. In Back Dale there are numerous ant hills amongst the short species rich turf on the south facing slope, in which abundant species include sheep's fescue Festuca ovina, quaking grass Briza media, false oat grass Arrhenatherum elatius, rock rose Helianthemum nummularium, thyme Thymus praecox and fairy flax Linum catharticum. The more local autumn gentian Gentianella amarella and clustered bellflower Campanula glomerata also occur. The underlying chalk has been exposed in stretches along this slope, corresponding with the site of an old plantation which has now been felled. An impressive earthwork with a species rich, even turf, occupies the valley bottom. In Vessey Pasture Dale, the grassland contrasts with that of the south facing slope in Back Dale. Absence of grazing has favoured rank growth of upright brome Bromus erectus although the herbs salad burnet Poterium sanguisorba, bird's foot trefoil Lotus corniculatus and dropwort Filipendula vulgaris are still abundant. The north facing slopes in Back Dale and those at the western end of Vessey Pasture Dale are less species rich, indicative of a lower calcareous influence, but herbs such as pignut Conopodium majus, devil's bit scabious Succisa pratensis and tormentil Potentilla erecta are present.
