Creator:: Hobbs, Stephen D., Oregon State University. Forest Research Laboratory, Byars, R. H ., Henneman, D. C., and Frost, C. R.
Abstract:: The effects of artificial shading and aspect on the performance of 1-0 container-grown Douglas-fir seedlings were evaluated 1 year after outplanting on four different aspects in southwest Oregon. The test areas, all characterized by steep slopes and shallow, skeletal soils with a surface mantle of loose rock and logging slash,...

Abstract:: The effects of naturally shaded microsites on survival and height growth of natural and planted seedlings were evaluated after an initial shelterwood harvest in the eastern Siskiyou Mountains of southwestern Oregon. After 2 years, the probabilities of survival for planted Douglas-fir (84 percent) and ponderosa pine (56 percent) were significantly...

Creator:: Hobbs, Stephen D. and Oregon State University. Forest Research Laboratory
Abstract:: One-year-old container-grown Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings were outplanted on north, east, south, and west aspects on steep, skeletal Xerochrepts in southwest Oregon. After 2 years, survival rates were highest on north and south aspects, but biomass production (dry weight) was greatest on the west aspect. Shadecards, used to...

Creator:: Hooven, Edward F. (Edward Frank), Black, Hugh C., 1941-, and Oregon State University. Forest Research Laboratory
Abstract:: Stands of brush and tree species of low commercial value dominate many potentially productive forest lands in western Oregon. Site preparation to reduce competition from such vegetation will improve the success of reforestation efforts, as well as reduce the cost of controlling small mammals that destroy seeds and seedlings. Site...
