Frequency of Specific Lichens on Ash (Fraxinus excelsior)

This frequency data comes from the British Lichen Society's database of epiphytic lichens and the substrates (trees) on which they have been found. The data comes from the whole of Great Britain and Ireland and thus includes data from Atlantic woodland; thus some of the lichens found in Atlantic woodland have a higher rank in this list than they actually have in Sussex Lecanora chlarotera	2408
