Description

Description Bavington Crags are a small escarpment of the whin Sill where bedrock is exposed both in near vertical, low crags and as slabs on the dip slope. This site supports a distinctive flora, featuring several nationally uncommon species, which is found at only a small number of other sites on the whin Sill in Northumberland. This flora, which is associated with shallow soils, occurs here within a mosaic of acid grassland types of more widespread occurrence. The dip slope exposures of whinstone are colonised by an unusual plant community including, most notably, chives Allium schoenoprasum, hairy stonecrop Sedum villosum and bristle club rush Isolepis setacea as well as annuals such as changing forget-me-not Myosotis discolor, field madder Sherardia arvensis and early hair grass Aira praecox. The drier soils of ledges on these low crags support maiden pink Dianthus deltoides. The rock outcrops lie within a matrix of acid grassland dominated by crested dog’s tail Cynosurus cristatus and locally by mat grass Nardus stricta. There are small areas of wet, flushed, ground with mat grass, carnation sedge Carex panicea, spring sedge Carex caryophyllea and cuckoo-flower Cardamine pratensis as well as small areas of species rich grassland on lime soil with red fescue Festuca rubra, wild thyme Thymus praecox, salad burnet Poterium sanguisorba and lady’s bedstraw Galium verum.
