Urban lichens 1 features 49 lichens found growing on trees and wood, including sawn wood (like fences, gates and park benches).
Illustrated with colour photographs throughout. The reverse side includes an easy-to-use visual lichen identification key.
This is a good time to look at urban lichens, as levels of sulphur dioxide, air pollution and acid rain have been falling rapidly. Many leafy lichens are growing in sites in central London where they may not have been present for 200 years.
