I took pictures of these trees recently on our camping trip. The moss grows on them like crazy. It looks soft, but it is not. It is kinda crispy and looks as though you could just pull it off the tree. But, you actually can't. I tried. It's so secure that I had to pull, but it just ripped it instead. It falls off the tree naturally lining the ground beneathe. Since it had just rained, there was more on the ground than usual. My friend and I gathered two paper bags full to bring home.
Does anyone know why it grows on the tree like this?
