Although these hay meadows are clearly dominated by herbaceous species as opposed to grasses, the unusually high abundance of yellow rattle (Rhinanthus minor), white clover (Trifolium repens) and often common sorrel (Rumex acetosa) and scarcity of bird’s-foot trefoil (Lotus corniculatus) suggest that the meadow has been agriculturally improved. However, these flower-rich meadows are of considerable biodiversity importance and attract large numbers of bees, butterflies and other pollinators. The scarcer hay meadow plants tend to be absent from these sites.
