This reserve covers 5 ha and is owned by the Leicestershire and Rutland Trust. It is a Site of Special Scientific Interest and a National Nature Reserve. The fields lie on Boulder Clay, a heavy 'blue' clay containing much fragmented chalk and limestone. They support a flora once typical of such calcareous clay pastures in Leicestershire and Rutland. Notable species are: adder's tongue, cowslip, green-winged orchid, common spotted-orchid and water avens in spring and early summer; agrimony, great burnet and yellow rattle later in the year. The railway line has a partial covering of trees and scrub with buckthorn and dogwood, overtopped by oak, ash and crack willow in places. All areas are good for butterflies such as grizzled skipper and green hairstreak.
