Things To Look Out For
This site is 58 hectares of flower-rich chalk grassland with an abundance of wild flowers and butterflies. Shetland sheep roam the down throughout the year eating the grass, keeping it short to prevent the flowers being shaded by taller grasses. The sheep also browse the hawthorn and bramble to reduce their spread over the open down. Most butterflies like warm sunny places, so some scrub and trees are kept to shelter the ground from the cooling wind. There are also ramparts of the Iron Age hill fort cut into the hill, buried ruins of the Norman chapel that gives the site its name and several rectangular burial mounds along Plague Pit Valley which mark the location of mass graves.
The sites offers spectacular views over Winchester, the Itchen Valley and the surrounding countryside.
Short downland turf rich in wildflowers or herbs such as bird’s-foot trefoil, salad burnet and dropwort. A square metre of turf will contain over 20 different flowers. Delicate orchids such as musk orchid, frog orchid and autumn lady’s tresses can be found on the south facing hill slope through the summer. There are over 25 different butterfly species that breed on the site. Most striking are the marbled white, chalkhill blue and brown argus.
Hampshire & Isle of Wight Wildlife Trust manage our nature reserves for the benefit of wildlife and we would like to thank all of our visitors that take care when walking on our nature reserves. We are working hard to engage with the dog walking community, in particular those that visit our nature reserves with their dog. The Trust’s "Dogs on Reserves" project has produced a leaflet that explains how to act responsibly on our nature reserves, along with some general guidance for dog walking visitors and advice about walking amongst cattle.
