Caldonia Lichen

I found these lichens growing on a fallen incense cedar tree. When I look up close at this miniature environment, I am fascinated by how much terrestrial life reminds me of the sea. This lichen's structure and vibrant colors look like a coral reef. It is easy to imagine small fish, eels, and other creatures darting in and out.

Lichens are such a mysterious life form. They are a symbiotic union between an alga and a lichen. They grow in a myriad of beautiful shapes, sizes, and colors. As you walk around the arboretum, look for them hanging from branches, wrapped around limbs, and encrusting tree trunks. You can also find them clinging to the surface of rocks. They live in a diverse range of habitats from the desert to the alpine tundra. There are approximately 3600 species in North America!
