Lichen it? I’m lovin’ it!!

Here is a special treat; a guest birthday blog from our resident econerd, Clemence..

On both a previous trip to Cape Point and on the recent berg trip we came across some lichen growing on the rocks. Lichens are an indicator species and a sign of good air quality. They are particularly sensitive to sulfur dioxide, a gas emitted from exhaust and industrial fumes, and so are rarely found in large cities and towns. They are often overlooked but are an essential barometer of a healthy ecosystem. It was great to see such healthy examples in different parts of the country, and of course to breathe some fresh air.
