The air quality in Cornwall is as good as anywhere in the UK (a great deal better in fact, than most places)….and  that’s why it’s so easy to find such stunningly healthy examples of clean air-loving Lichens growing on every other rock, wall, tree trunk or branch right across the county. I took lots of Lichen photographs while I was in Cornwall this time around (July/August 2008) and I’ll upload a couple more of them when I do a write-up over the next few days.
