Abstract
Seed dispersal of white spruce (Picea glauca) (Moench) Voss) from stands bordering a large clearcut and a strip cut was studied. Seedfall fell sharply with distance from the clearcut edge to 100 m, but even at 300 m the average dispersed seed density exceeded 740 000 seeds/ha or 3% of that recorded within the stand. Dispersed seed density in the middle of the 200-metre-wide strip cut exceeded 1 300 000 seeds/ha or 20% of that recorded within the bordering stands. About one-third of the seeds was disseminated by the end of September.
