Description

Fall seed-dispersing species, birch (Betula papyrifera Marsh.), alder (Alnus crispa (Ait.) Pursh), and black spruce Picea mariana (Mill.) B.S.P.), and summer-seeding species, aspen (Populus tremuloides Michx.), balsam poplar (P. balsamifera L.), feltleaf willow (Salix alaxensis (Anderss.) Cov.), Scouler willow (Salix scouleriana Barratt), and Bebb willow (Salix bebbiana Sarg.), were artificially sown on seedbeds created by experimental burning in the upland black spruce/feather moss forest types in interior Alaska. At least 40% of the seeds dispersed in the fall had germinated before dispersal of summer seeds began. Germination occurred on moderately and severely burned seedbeds but not on scorched and lightly burned surfaces. Seedling survival occurred almost exclusively on severely burned surfaces. After 3 years, 82% of the plots containing some severely burned surfaces and sown with seeds from species seeded in the fall were stocked whereas 32% of the plots sown with species seeded in the spring and with the same seedbed condition were stocked.
