Lichen
I've a friend who is studying an environmental science course with the Open University and I occasionally drop round for a chat.
Today, he revealed that he has to do a survey on the effects of pollution on lichens. He's not exactly looking forward to it...
So, we got chatting. I at least have the advantage of having some interest in lichens. I don't know much about them, but you don't need much of a head start to be ahead of zero (which, let's face it, are where most people are when it comes to lichens)
I told him to do his survey in churchyards. Many classic lichen surveys have been done in such places. They have nice flat stone surfaces, and, perfect for the purpose of surveys, all those nice flat stone surfaces even have dates on them.
Most people don't 'see' lichens. Next time you walk down a road, look at the surfaces of pavements, curb stones and walls. The odds are high that you'll see at least three species of lichen in just a couple of minutes.
