Abstract:: Reliable estimates of plant biomass and leaf surface area are essential for studying primary production, nutrient cycling, hydrology, wildlife management, and fire. This paper presents equations that can be used to make such estimates for most plant species-trees, shrubs, and herbs-dominant in western and central Oregon.' We also document the...

Creator:: Del Rio, Ernest, Berg, Alan B., and Oregon State University. Forest Research Laboratory
Abstract:: Growth was assessed for Douglasfir reproduction which had established naturally beneath three intensities of overstory thinning in a 65-year-old stand of Douglas-fir on the east side of the Oregon Coast Range. The age of advanced reproduction ranged from 4 to 15 years. Understory environments were described in terms of sunlight,...

Creator:: Newton, Michael, 1932- and Oregon State University. Forest Research Laboratory
Abstract:: 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-and-burn" method. The other was partially cleared by spraying with herbicides. Seedlings lifted and planted in December, January, February, and April were...

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...

Creator:: Butler, David A., LeDoux, Chris B., and Oregon State University. Forest Research Laboratory
Abstract:: The authors describe a new,theoretical methodology for evaluating the replacement of a single piece of logging equipment with a predetermined new model. The example is for a specific piece of equipment and gives results unique to the data-base analyzed, but the application typifies procedures, required data, and results of the...

Creator:: Dilworth, J. R. (John Richard), 1914- and Oregon State University. Forest Research Laboratory
Abstract:: Young western hemlock stands in the Coast Range of Oregon will contribute to the commercial timber supply of the region in the future, the extent of the contribution depending on environmental and cultural factors. The relative diameter and volume growth of crop-trees in the stands will be increased substantially by...

Creator:: Gibbs, Kenneth C., Van Hees, Willem W. S., and Oregon State University. Forest Research Laboratory
Abstract:: A detailed cost analysis was performed on 111 U.S. Forest Service campgrounds in the Pacific Northwest (Region 6). Five experience levels were analyzed to estimate facility, operation and maintenance, and opportunity costs. Cost functions, estimated by multiple linear regression analysis to predict the effect of size (number of sites) and...

Creator:: Stine, R., Gordon, J. C., Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: Black cottonwood (Populus trichocarpa Torr. & Gray) cuttings were collected from five Oregon provenances along a north-south gradient. Cuttings from each provenance were grown for 1 year at two locations, one on the Willamette Valley floor and the other on the Valley margin. Survival at both locations was poor. Stem...
