Naturally Rot-Resistant Woods - Garden

For many species of wood today, the only way to get highly resistant, old-growth wood is to salvage it from structures that are being torn down or from rivers and lakes where it sank a century ago. (Underwater, where there is very little oxygen, wood lasts for decades, or even centuries, with little decay.)

CBD-111. Decay of Wood - NRC-IRC

All wood-rotting fungi require some air for growth, and many species die quickly if they are deprived of it. The air-moisture balance in the cells within the wood, therefore, is a most important factor controlling the susceptibility of wood to decay. Fungi need oxygen for the oxidation of sugars, which they use for growth and the supply of energy.
