Abstract:A 3-year experiment to determine feasibility of spot seeding western larch in spring yielded information on favorable aspect and dates for planting, effectiveness of two seed treatments in increasing germination, and means for preventing loss to rodents. Sowing stratified seed on bare soil on north-facing slopes soon after snow-melt produced best germination and survival. Seed soaked in hydrogen peroxide and seed that had no pretreatment germinated poorly. Seedling survival was low on south-and west-facing slopes regardless of seed pretreatment. Drought, insolation, frost heaving, and fungi caused most seedling mortality. Losses to rodent depredations were insignificant and hardly justified use of control measures.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
