Live-storage of Picea abies for two summers after storm felling in Sweden
After recent severe storm fellings in Sweden, as harvest, transport, and storage capacities were insufficient, interest in live-storage (leaving windthrown trees in the stand) increased. This study follows windthrown Norway spruce (Picea abies (L.) Karst.) trees during 20 months, i.e. two summers, of live-storage in southern Sweden. Moisture content, blue stain, and storage decay were compared in trees from a site with all trees windthrown and a site with scattered windthrows. After the first summer of live-storage, the quality losses were small. After 20 months, the trees had dried significantly and had numerous infestations of blue stain and storage decay. Trees from the site with scattered windthrows were of better quality compared to trees from the site with all trees windthrown. Live-storage is a suitable method for one year of storage, but the second year losses in wood quality are considerable.
