About the reserve

Copper Hill road verges have a particularly rich limestone flora with much rock-rose, horseshoe and kidney vetches, spiny restharrow, purple milk-vetch and fairy flax. Butterflies include brimstone and common blue. This was the last known Lincolnshire locality for the chalkhill blue butterfly, and is the most northerly point for man orchid in Britain. Glow-worms may be seen here, and on Duke's Covert.

The adjoining Duke's Covert is old limestone grassland, which accommodates landing lights for the nearby Barkston Heath airfield. The Covert had become overgrown and invaded by bracken and scrub of gorse and hawthorn, but with continued careful removal of scrub, and with mowing and grazing, the interest has being restored.

Many limestone flowers thrive here, including common and greater knapweed, mignonette, burnet-saxifrage, dropwort, field scabious and columbine, a scarce plant in Lincolnshire. In spring there is a colourful display of cowslip, hairy violet and early-purple orchid. As spring rolls into summer the flora includes St John's-wort (both perfoliate and beautiful), rock-rose, horseshoe vetch, dropwort and small patches of purple milk-vetch and lesser meadow-rue. In high summer the scabious and knapweeds attract butterflies in good numbers.
