Try & find what's called a spud, made to peal the bark off tree's without harming the layer under.
I wouldn't recommend trying anything like a tarp, it'll trap moisture & will probably feed mold. You could try & protect it, but it would have to be a roof-like structure high enough to let the logs stay dry. Might be difficult.
