Iceland has very few trees, yet it is incredibly lush due to all the moss and lichen that cover, well, everything. Most of the lava rocks are covered with soft green moss, or possibly lichen. I have yet to identify the actual kingdom, much less species, of the “living stuff growing on the rocks” that I photographed. Whatever the stuff is, it is gorgeous. It also gave me a great reason to play with my new macro lens. If anyone who reads this can identify what I photographed, even if only to narrow it down to fungus, plant, or lichen, I would be grateful if you would leave me a comment. I would really like to know what they are. Edited to add: Here is a link to an interesting article about the ecosystem consisting inside glacier mice.
