Lichen

Lichens help the environment in key ways. Besides fixing nitrogen, they produce chemicals that can break down rocks and release minerals. This gradual decomposition leads to the formation of soils so that plants can thrive. Lichens also absorb pollution and their presence is an indicator of cleaner air.


Saw lots of lichen today and was quite fascinated by it, so thought I would look it up online, and found the above.


A pleasant day but with a few showers at times.
