Hieracium britannicoides, Confused Hawkweed, is a Welsh endemic plant confined to Caernarvonshire (v.c.49) and Denbighshire (v.c.50). Field surveys 2009-2019 indicate at least 390 plants in eight sites. The IUCN threat status is ‘Vulnerable’. The main threats are spread of alien woody species (especially Cotoneaster), which without continued management will become a serious problem in the future, and over-grazing or spread of scrub from under-grazing.
