RE: What's that green stuff everywhere? It's Lichen!
This is pretty awesome! Everything in nature has it's purpose, but just don't know about it..
I just remembered that I think saw some program saying that reindeer and other animals eat lichens (and moss) in winter when other food is hard to find under the snow.
Do you know @haphazard-hstead here on Steemit? She knows A LOT about wild plants and weeds.
Yes, it's true! Lichen is used as a food source when plants are scarce because of the snow. It also grows a lot in the Tundra and is an essential part of animals survival!
