Below are examples of mosses and lichens you might encounter in or above the intertidal on exposed shores. I haven’t discovered too many, so it’s a small list. Identification is a challenge even with the readily available field guides and online resources (see references at the bottom of the page). I give my photographic take on the mosses and lichens I’ve encountered and add a natural history note if I have something to say. The organization and common names are my choices, and all photos are from northern Oregon unless noted in captions.
Let’s explore some shoreside mosses and lichens!
The moss shown below is from a single rock set back in the cobbles. It gets plenty of sea spray, some splashes, and an occasional dunking, so it’s safe to say this moss has a degree of salt tolerance.
The lichen shown below is from a single rock set in the cobbles at the back of the beach. It gets plenty of sea spray, some splashes, and an occasional dunking, so it’s safe to say this lichen has a degree of salt tolerance.
