The lichen symbiosis is very powerful. Lichens colonise bare rock and pave the way for other life forms. Between them they make over 1000 unique chemicals. Join lichenologist Allison Knight on a walk in the Botanic Garden to take a closer look at the awesome miniature world of lichens living on rocks, including a species that can survive exposure to outer space!
Bring a hand lens or magnifying glass if you have one.
