Outdoor Event, 10.30am-4pm
The first part of the day will be spent looking at the diverse flora in the wide range of habitats resulting from the reclamation of Walltown quarry by Northumberland National Park (NNP). Plants of the Whin Sill include scarce Common Cudweed Filago vulgaris and Common Rock-rose Helianthemum nummularium. Other notables at the site are Adders-tongue Ophioglossum vulgatum, Common Twayblade Listera ovata, and a variety of orchids. After lunch a circular walk of around 2 miles takes us up to and along Hadrians Wall to look at the rare Chives Allium schoenoprasum near Walltown Farm and grassland plants along the way.
Even the paths at Walltown can be muddy so walking boots or similar are recommended. Bring a packed lunch. Toilets and a snack bar are near the car park.
