Direct Seeding of Paper Birch in Strip Clearcutting
Abstract:Paper birch (Betula papyrifera Marsh.) was successfully direct-seeded on 50-foot wide, east-west oriented strips which were clearcut in a 60-year-old second-growth forest of northern hardwoods located in eastern New York. Spot seeding on tractor-scarified areas gave the best results but data show that broadcast seeding, if conducted early in the spring, should be equally successful. Spot seeding following spot scarification with a mattock gave the least satisfactory results. Shade, beneficial for germination and initial survival, became the major cause of seedling mortality during the second growing season and was also responsible for reduced height growth of seedlings growing near the south border of the clearcut strips. Trees producing this shade should be cut as soon as possible alter the first year.
