Abstract:Douglas-fir seedlings were planted on four difference microsites in the Tillamook Burn of northwest Oregon and slipped to simulate browsing by deer. Survival of seedlings after one field growing season was significantly greater on a recently disturbed site with relatively sparse vegetative cover than on sites dominated by stands of Vaccinium parvifolium, Rubus parviflorus, and Acer circinatum. Survival was also correlated with the amount of clipping. Height growth of unclipped seedlings was poorest on the more shaded site. Light to moderate browsing during the first winter field season did not adversely affect survival.

- 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.
