Abstract

For some years forest investigators in the Pacific Northwest have been aware of the considerable quantity of tree seed which accumulates in the duff of heavy virgin timber stands and apparently retains its vitality for a few years in a sort of natural cold-storage condition. The major portion of the luxuriant regeneration which frequently follows logging and forest fires in the western white pine forest of northern Idaho has, in fact, been attributed by many foresters to this stored seed. The theory is that wholesale germination is stimulated by removal of the dense overwood shade and consequent raising of temperature of the cold and damp storage medium.
