Description
The limestone lichen index applies to both rock and associated bare ground habitats in hard limestone landscapes (Edwards & Sanderson, in prep). The list comprises 104 species balanced to cover southern and northern non-montane (below 600m) limestone in Britain; TNTN scoring (3.4.7) should be used for calcareous assemblages above 600m. The index is designed to cover coherent outcrops of limestone in a distinct landscape relationship (spatial, geological or climatic) covering areas of between 100 to 1,000ha. The number of recorded species/species pairs in Table 5 is used to assess sites. A site with 30 or more should be considered for notification.
