Likin’ lichens

We had an excellent (if sometimes grey) morning with Dr Rebecca Yahr, Lichenologist, from the Royal Botanic Garden Edinburgh on Sunday. As you’ll know, the Edinburgh Shoreline project is run by the Botanics, so we’re lucky enough to work with Becky, but Sunday was all about unleashing her on the general public, and what a day it was!
