Section 7 Lichen List

Lichens listed under Section 7 of the Environment (Wales) Act (2016). Species (and lichen communities) on this list are considered to be of "principal importance for conservation of biological diversity in Wales"

One species, Arthothelium dictyosporum, that was listed in the preceding Section 42 of the Natural Environment and Communities (NERC) Act 2006, but was recorded from Wales in error has been removed from the Section 7 list. A second lichen, Pyrenula nitida, also has no confirmed record from Wales, but is still included.
