Photo 3. on left and 4 Is this kind of wood/ring safe its made of beechwood which the internet says its safe but its not on the official safe list or unsafe list. Opinions please?

Photo 5. Is this rotting partially and is it safe to use rotting wood and does it break down easier in crabitat. Its camellia wood
