History of Botany in Upper Teesdale
First records mentioning Teesdale Plants were published in 1677. Plant discoveries continued through the 18th and 19th centuries, boosted by the Napoleonic Wars curtailing travel abroad and by the growth of the railways. And new species have been discovered through the 20th century right up to the present. These include plants identified by John O’Reilly surveying Widdybank and Cronkley Fell for Teesdale Special Flora Trust.
