Ring-Profiler technique developed in our previ ous study (Vahey et al ) was employed to measure wood density and anatomical properties of a Douglas-fir wood core sample. The objec tives are (1) to provide some understanding of the effects of growth suppression on the charac teristics of within-tree wood density and tracheid. Calibration of volume and component biomass equations for Using data from destructively sampled Douglas-fir and lodgepole pine trees, we evaluated the performance of regional vol-ume and component biomass equations in terms of bias and RMSE.

Six series of photographs display different forest residue loading levels, by size classes, for areas of like timber type and cutting practice.
Information with each photo include measured weights, volumes and other residue data, information about the timber stand and harvest or thinning actions, and fuel ratings. These photo series provide a fast and easy-to-use means for.

Research work continued in the Pacific Northwest and by the early s the evidence was there to convince most professional foresters that clearcutting was the most desirable method of tree harvesting in the Douglas-fir region.
These data were compelling from the economics of harvesting and the planting and growth of seedlings that need direct sunlight.

Logging debris contains significant amounts of C and N, and there is concern that increased biomass re-moval (e.g., utilization of all logging-debris residue) could Received 12 September Accepted 3 May Published on the NRC Research Press Web site.
There was an overall drop of moisture content in forest residues from 52% (freshly cut) to less than 20% over the month study period (Kizha et al. Processed treetops (i.e., stemwood only. The differences in volume suggest that management of residues in the Douglas-fir region will be more complex than that required for the ponderosa pine region.
Typically, residue management techniques fall into four broad categories (Jemison and Lowden ). LOGGING. A thei on the methods and coot of logging as carried on in the Northwst. The region studied lies alon the Columbia Riverbetween the mouth of the Villamette River and th Pacific Ocean and is known as the lo-rer Columbia River Region.
The timber is a fine grade of Dougla3 Fir and is used in all lines of construction wrk both at home and abroad. Highlights We describe how vegetation and logging debris interacted to affect Douglas-fir growth.
Vegetation and debris altered soil water, nitrogen uptake, and temperature. Seedling growth was greatest with 80% debris cover and absence of vegetation. Reduced herb cover from 40% debris cover increased soil water and seedling growth.
Severe seedling nitrogen deficiency resulted from 80% debris Cited by: Comparison of decomposition models using wood density of Douglas-fir logs. Can. For. Res. Logs of Pseudotsuga men:iesii (Mirb.)

With a view to reducing the time needed to produce planting stock, experiments were carried out with white spruce and three other coniferous species from Wisconsin seed in the longer, frost-free growing season in Florida, vs.

This publication presents tables on the behavior of fire and the resistance of fuels to control. The information is to be used with the photos in the publication, 'Photo Series for Quantifying Forest Residues in the Coastal Douglas-fir Hemlock Type, Coastal Douglas-fir Hardwood Type' (Maxwell, Wayne G.; Ward, Franklin R.
Gen. Tech. Rep. Elevated dissolved carbon (C), nitrogen (N) and phosphorus (P) concentrations are frequently observed in surface water soon after clear-cutting of boreal coniferous forests.
It has been suggested that they originate from the fine logging residues whose decomposition may be accelerated as a result of changes in soil temperature and moisture by:. GTR () Silvicultural research and the evolution of forest practices in the Douglas-fir region, by Robert O.
