 The SSSI citation sheet describes the site as having an "exceptionally diverse unimproved calcareous grassland flora".The richest grassland communities are situated on the thin and stony soils of the steeper west-facing flanks of the hill.Over 200 species occur in the sward, including Salad Burnet ("Sanguisorba minor"), Dropwort ("Filipendula vulgaris"), Fairy Flax ("Linum catharticum"), Kidney Vetch ("Anthyllis vulneraria") and Dwarf Thistle ("Cirsium acaule").
