Lichens are small and easy to overlook, but they are amazing. These tiny symbiotic communities of fungi and algae and cyanobacteria can weather the cold temperatures and dry air of winter. How do they do it?
They go dormant. Some have anti-freeze chemicals in their cells to keep from - well, freezing and bursting open. Their superpower: they can pick up with photosynthesis once the weather warms up and the moisture returns. Find out more about lichens here.
Go Lichen Looking around your neighborhood.
Check tree trunks and branches, rocks, stone walls - I've even found lichens growing on park benches!
