Claire Dalby's wallchart of lichens on trees
Pat Wolseley has written a set of notes to accompany Claire Dalby's Lichens on Trees poster. Read about how the arrangement of the poster's lichens indicates species that tolerate similar environmental conditions including man-made pollution.
All future purchases of the poster will be accompanied by the double-sided A4 sheet of notes. If you have previously bought posters, the notes can be freely downloaded from the BLS Shop at https://britishlichensociety.org.uk/the-society/bls-shop
