Would very decayed logs(think cellulose) be worthwhile using for Hugelculture or would their nutritional value be too diminished? They would still hold water well I imagine. I have some firewood logs left on ground
in woods for several years. (I think the beetles have had their way with them and move on to greener pastures)!
Also: is lichen covered bark beneficial(esp regarding toxicity)?
