Lime Lichen Picture of the Week

Lime Lichen
Lime Lichen – The main lichen growing in the Granite Dells is either orange or a pale green. Every so often, you’ll find a bright green patch such as this.

In last week’s post, I wrote how the Granite Dells boulders weren’t just bare rock, but they’re covered with living organisms which gives them color and texture. As you hike along the trails and take a closer look, you’ll find lichen, moss, fungi, and things that only a botanist could name growing there. Although they resemble a plant, lichen is a relitive of algae. They don’t put down roots, but instead, they get water and nutrients from the air. Lichen has a surprisingly long lifespan, but they don’t handle pollution well. When we were landscaping our Goodyear home, Anne and I specifically picked out some boulders that had a green specimen growing on them. Within six months, all the growth vanished.

There are two predominate colors of lichen in the Dells, an orange and another that is light green—seafoam if you will. Occasionally there’s a patch of a bright green specimen that catches the eye, and that’s how I happened upon this shot. The green was a small part on the larger rock surface, so to make it stand out, I moved in close enough and made it the subject of this photo. I like the way the bright green dominates the other muted colors. In all, I count four species growing in this shot. Because there’s not a structure in it, the abstract image is about color and texture. I call it Lime Lichen.
