In February of 1975, the School of Forestry sponsored a series of lectures and discussions on the topic, "Forests of the World-Future Resources Conflicts." The objectives of these presentations were to examine prospects for future forest use, the demands that will be made on forest resources of all sorts, the...
Urbanites who own forest land belong to a larger category of owners often referred to as small woodland owners. As a group, small woodland owners have been the subject of much investigation. Little research, however, has focused specifically on urban-dwelling owners who, as defined by the Census Bureau, live in...
Two-year-old Douglas-fir bareroot seedlings were hoe- and auger-planted on droughty south and southwest aspects in southwest Oregon. After 2 years, no differences in height, diameter, or seedling biomass could be detected. Auger-planted seedlings survived significantly better on the southwest aspect.
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...
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...
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...
"An important limitation In the study of tree roots has traditionally been the time necessary to excavate roots without injuring their fine structure. Thus, many root studies have been based on small samples and consequently contain large errors of estimation. This Note describes how large numbers of root systems from...
"Because forest managers and geneticists need basic information about natural variations in populations of red alder, we studied conelet and seed characteristics, as well as early growth, of this species along an elevational transect in the Coast Range of Oregon."--P. [1].
