The invention relates to a method for stocking and preserving green round wood and sawn timber, which is stored in an airtight and lighttight sealing cover. The oxygen inside the cover is decomposed by the respiratory process of fungi, bacteria and wood cells that are still alive, thereby forming CO2 and H2O. Fermentation processes also lead to the decomposition of hemicelluloses and saccharides which are converted to organic acids and CO2. The oxygen content in the cover is less than 0.1 vol. % after an adjustment time of 3 to 10 days of total stocking, while said CO2 content rises to more than 21 and up to 40 vol. %. This method enables green round wood a swan timber to be stocked over long periods without wastage or environmental damage.
Method for preservation storage of green round wood and sawn timber comprising stocking green round wood or sawn timber under a cover, whereby respiratory and fermentation processes by fungi, bacteria, and respiratory processes of wood cells that are still alive are promoted, wherein the cover is absolutely air-tight and light tight and thereby the oxygen content inside the cover is less than 0.1 vol. % after an adjustment period of 3-10 days during the entire storage time, and the CO2 content is higher than 21 and up to 40 vol. % which to a great extent prevents the growth of wood-destroying fungi, and the cover is a double, two-layered film whose black internal surface prevents the light from entering and thereby growth of algae, and whose white external surface reflects the sunlight.
