Lessons from Lichens

Perhaps Kaya will learn sooner than I did that Alders don't really have white bark, as it appears to here. That's really a lichen that lives on the tree...as quoted from this website: http://www.rainyside.com/natives/alder.html:
Epiphytic lichen (lichen that grows on trees) covers most alder tree bark, giving them an appearance similar to a birch tree. Covering the bark, the lichen makes mosaic patterns of white and gray with tinges of light pink. Where the air is free of pollutants, the lichen freely covers the bark. One lichen that frequently grows on alder is called Pencil script (Graphis scripta), a very old species dating back at least 25 million years. It is white with black fruiting bodies that look like small hieroglyphs drawn in pencil. Alder bark is one of its favorite hangouts.
Anyway, Gramms and Jules are helping her get to know lots of trees, as you see here next to the Breitenbush River just upstream of the cabin. I love the look on her face...SO inquisitive!
