Enrichment of Natural Regeneration Through Direct Seeding and Fill Planting in Logging Trails of Black Spruce Stands


Direct seeding and fill planting of black spruce [Picea mariana (Mill.) B.S.P.] were assessed in logging trails after irregular shelterwood cutting in the boreal forest of Québec, Canada. Two growing seasons after harvest, direct seeding increased seedling establishment when compared to control plots, but seeded seedling density represented only 17 percent of seeds initially deposited. Seedling establishment increased with increasing soil moisture. Planted container seedlings responded well with mean terminal shoot growth of 4.7 cm (1.9 in) yr-1. Terminal shoot growth of planted seedlings decreased with increasing soil moisture. Results suggest potential for improvement of logging trail regeneration with fill planting.
