The reserve is a wonderful example of the traditional chalk downland that was once widespread in Wiltshire and is designated a Site of Special Scientific Interest due to the rich variety of its grassland plants. What can be seen here? From May early purple and other orchids blossom on the slopes - common spotted, fragrant, pyramidal, bee, frog and autumn lady’s-tresses. Here too are clustered bellflower and the nationally rare dwarf sedge. Its many butterflies include the rare Adonis blue, common blue and marbled white. Most are attracted by the trefoils and vetches that provide food for their caterpillars. On late summer evenings glow worms sparkle on the slopes. These are not worms at all, but beetles. The wingless females glow for a few weeks to attract the flying males, only to die soon after laying their eggs. Look out for a large, shiny oil beetle in early spring, or the narrow-bordered bee hawkmoth – a day-flying moth, which looks like a bee. Listen for the rustle of grasshoppers at ground level and the pure notes of the skylark above. The reserve is grazed by our own Dexter cattle, giving us flexibility to vary the grass height to be best for insects. Since we acquired the reserve in 1988 biodiversity has increased. Grazing also prevents invasion by scrub and coarser vegetation. How can I get here? Download directions
