The open grassland is rich in herbs, with fescues "Festuca ovina" and "Festuca pratensis", crested dog's tail "Cynosurus cristatus", spring sedge "Carex caryophyllea", and locally quaking grass "Briza media" as dominants. Abundant herbs include ladys’ bedstraw "Galium vernum", hedge bedstraw "Galium mollugo", creeping thistle "Cirsium acaule", fairy flax "Linum catharticum", bird's-foot trefoil "Lotus corniculatus", horseshoe vetch "Hippocrepis comosa", kidney vetch "Anthyllis vulneraria", chalk milkwort "Polygala calcarea" and felwort "Gentianella amarella" and several species of orchids. There is also Rock Rose, Wild Thyme, and Clustered Bellflower. These flowers in turn provide for rare invertebrates such as "Osmia bicolor", a scarce solitary bee. There is a decidedly neutral element in the flora which suggests that the soils may in part be derived from superficial drift or loess.
