Does lichen on trees indicate clean air?
Lichen, which consists of a symbiotic relationship between a fungus and an alga, is sensitive to atmospheric pollution including nitrogen and sulfur emissions that lead to acid rain, as well as toxic lead and mercury emissions. This sensitivity makes lichen a valuable biological indicator of air quality.
What are the 3 types of lichen?
In a lichen, the mycobiont produces a thallus, which houses the photobiont. There are three major morphological types of thalli: foliose, crustose, and fruticose.
How do you stop lichens from spreading?
You could try to physically remove it, but this should be avoided as it would probably do more damage to the bark and branches. Lichens can be controlled to some extent by improving air circulation around the plant – prune out any overcrowded branches and remove vegetation growing around the affected plant.

How does lichen indicate air quality?
How do you identify a lichen?
In order to identify lichen to species, lichenologists use common household chemicals and some not-so-common chemicals to test the color reaction of the unique compounds found in the structure of the lichen, as well as using a lichen key to distinguish between species.
