You will see them on Georgian Bay this summer covering the most exposed rocks in hues of yellow, orange, grey and green – these wonderful organisms are often confused with moss. We admire their beautiful colours however many don’t realize the critical role lichens play on the Bay!
A unique combination of fungi and algae, lichens form and spread on surfaces, building a foundation for moss, grass and other plant life to grow under the harshest of conditions. They release an acid that breaks down the rock but over a very long period of time. And when illuminated by the final rays of a Georgian Bay sunset, their glow is spectacular! ❤️
Lichen can live for thousands of years and survive under extreme weather conditions, their biggest threats being pollution and urban sprawl.
One of the many amazing features of lichen is that they absorb their nutrients from the atmosphere meaning their presence in an area indicates healthy air quality. So when you’re out exploring beautiful Georgian Bay this summer, remember to find the lichens and breathe deeply!
