“A tree is alive, and thus it is always more than you can see. Roots to leaves, yes-those you can, in part, see. But it is more-it is the lichens and moss and ferns that grow on its bark, the life too small to see that lives among its roots, a community we know of, but do not think on." (Elizabeth Moon, Oath of Fealty)
@marlboromaam I learned that about lichen many years ago when I was in college. I wonder if lichen has adapted to the worse air quality that is more prevalent today.
