Description

Area, 6 ha. 15 ac. Description Linbrigg is an open ash / hazel Fraxinus excelsior / Corylus avellana wood situated on andesite crags at the bottom of a steep northwest facing slope above the River Coquet. Woodland plants grow extensively on the steep slopes and the rich herb flora includes wood sage Teucrium scorodonia, valerian Valeriana officinalis, ivy Hedera helix and male fern Dryopteris filix-mas. Jacob’s ladder Polemonium caeruleum, a nationally rare native species, which is otherwise confined to a few localities in the Pennines and maiden pink Dianthus deltoides, which is more widespread but localised, grow on outcrops of andesite. Other Information The vegetation of the Cheviot andesite outcrop at this site has been described by C D Pigott 1958 'Polemonium caeruleum L' Journal of Ecology Biological Flora of the British Isles, 46, pp. 507–25. * Under Section 23 of the National Parks and Access to the Countryside Act, 1949.
