had some stacked scraps outdoors and noticed was surprised to find out which ones grew mold and to what degree
douglas fir had some but not a lot and it was whitish redwood had tiny amount and was whitish bamboo had the most and was blackish pine had blackish and whitish eucalpytus had some whitish on the bark but not the wood
thought bamboo would be resistant just due to the tolerance it has to wet environments but since it is a monocot and quicker to grow it may be quicker to break down
