Appendix 1 Extinctions Many of the species listed below are undoubtedly long since extinct, having disappeared with the last remnants of their habitats. For some species, the evidence for them ever having occurred in the County is very weak. Despite the above, the re-discovery of Marsh Lousewort (Pedicularis palustris) in 2005 and Parsley Water-dropwort (Oenanthe lachenalii) in 2008 shows that there is still some hope, however slight, that some species might be re-discovered.

Could this be an error for Hydrocotyle vulgaris? 77
