If you’re interested in lichens, then this day is for you! It’s a day for people who are fascinated by lichens but don’t know where to start with them. It’s a very gentle introduction to the world of lichens and the art (and science!) of telling one kind from another. Lichens are remarkable, often beautiful and they can be found in a vast range of locations. Based in Greenwich Park, we will look at the basic structure of lichens, concentrating on the main features used in identification. We will have an introduction to the issues of pollution that impact on lichens and their rapidly changing fortunes in London and what this tells us. We will be going outside to look at and admire lichens in the field and learn some common species, concentrating on those that grow on trees. We will identify some common lichens using a simple key and discuss the role of lichens in nature. Course fee includes FSC fold out charts: Key to Lichens on Twigs.
You should, at the end of the course, feel able to use basic identification guides with some confidence and be able to identify some of the commoner lichens. You should feel eager and confident to find and examine lichens yourself and be more aware of their diversity.
