  Citation × Citation Citation Abstract Copy Title: Can we control brush by helicopter spraying before timber harvest? Author: Cline, G., Oregon State University. Forest Research Laboratory, Newton, Michael, 1932-, Howard, Kerry Megan, White, Diane E. Aerial application of fosamine ammonium or glyphosate at moderate rates was not adequate for controlling understory brush before final harvesting of mature Douglas-fir (Pseudotsuga menziesii) stands or for reducing vigor of post-harvest sprouting. Symptoms of herbicide injury were those associated with low application rates, suggesting that the canopy intercepted too much of the chemicals for adequate brush treatment. Site-preparation effects of logging were more pronounced than those of herbicide treatment in curbing future dominance by brush. Shrub species composition did not change as a result of spraying, logging, or both. Controlling understory brush with herbicides before harvest may require aerial application at higher rates or use of ground equipment where coniferous overstories are dense.

Forest Research Laboratory, Newton, Michael, 1932- The response of western hemlock (Tsuga heterophylla [Raf.] Sarg.) to two methods of site preparation for planting was compared. One site was cleared of mature brush by the "brown-crush-andburn" method. The other was partially cleared by spraying with herbicides. Seedlings lifted and planted in December, January, February, and April were compared, and lifting and planting dates were evaluated. Investigation of subsequent microenvironments and their interactions with seedling size showed that seedling size was critically important to the tolerance of residual vegetation.

  Citation × Citation Citation Abstract Copy Title: Terrace planting in the Oregon Coast Range : some implications Author: Starker, Bruce, Oregon State University. Forest Research Laboratory, Newton, Michael, 1932-, Blanchard, Gary Douglas-fir seedlings were planted in 1963 near Burnt Woods, Oregon, on land covered with grass, salal, or bracken to test the effects of terracing on regeneration. After 9 years, survival was best (about 95 percent) among seedlings machine-planted along the centers of the terraces and was better on south than on north slopes, although height of surviving seedlings was greater on north slopes. About half of the trees planted in the rough between terraces died, and the survivors attained only about one-half the height of trees planted by machine in the terrace centers. Planting in terraces should succeed on deep soil with slopes between 20 and 50 percent. Outward-sloping terraces are recommended to lessen soil disturbance, prevent ponding, and avoid need for water bars.
