  1. The influence of residue removal and prescribed fire on distributions of forest nutrients.

    The effects of two levels of residue removal (removal of all woody material larger than 15 x 180 cm and 10 x 120 cm) on the distribution of nitrogen and sulfur on the forest site and the added effects of post-harvest prescribed fire on those distributions were studied at two sites in the Cascade Range in Oregon. Nutrients lost from increased removal of residue were...

  2. Comparison of logging residue from lump sum and log scale timber sales.

    Data from 1973 and 1980 logging residues studies were used to compare the volume of residue from lump sum and log scale timber sales. Covariance analysis was used to adjust the mean volume for each data set for potential variation resulting from differences in stand conditions. Mean residue volumes from the two sale types were significantly different at the 5-percent...

  9. Fate of Hexazinone and Picloram After Herbicide Site Preparation in a Cutover Northern Hardwood Forest

    Herbicides show promise to improve the efficiency and economics of forest stand conversion and regeneration. However, the impacts of herbicides on forest ecosystems and the ultimate fate of these chemicals are not completely understood. A major problem in pine regeneration in northern mixed hardwood forests is competition from fast-growing and easily sprouting species...

  11. Logging damage using an individual tree selection practice in Appalachian hardwood stands

    Four West Virginia hardwood stands, managed using individual-tree selection for the past 30 years, were examined after the third and, in one instance, the fourth periodic harvest to determine the severity of logging damage. On existing skid roads, trees were removed with a rubber-tired skidder or a crawler tractor with a rubber-tired arch. Logging damage reduced...

  13. Alternate biomass harvesting systems using conventional equipment

    Three harvesting methods were field tested in two stand types. Costs and stand utilization rates were developed for a conventional harvesting system, without energy wood recovery; a two-pass roundwood and energy wood system; and a one-pass system that harvests roundwood and energy wood. The systems harvested 20-acre test blocks in two pine pulpwood plantations and in a...

  14. Dilute acid hydrolysis of paper birch : kinetics studies of xylan and acetyl-group hydrolysis

    Batch hydrolysis kinetics of paper birch (Betula papyrifera) xylan and its associated acetyl groups in dilute sulfuric acid have been measured for acid concentrations of between 0.04 and 0.18 M and temperatures of between 100 and 170°C. Only 5% of the cellulose was hydrolyzed for up to 85% xylan removal. Rate data were correlated well by a parallel reaction model based...

  15. Managing white and Lutz spruce stands in south-central Alaska for increased resistance to spruce beetle.

    Thinning is recommended for maintaining vigorous tree growth to minimize losses caused by spruce beetles (Dendroctonus rufipenni Kirby) and windthrow in residual stands of spruce in south-central Alaska. The anatomy of conifer stems, the variation in stem diameter growth, and the variability of tree response to wounding are discussed to explain why...

  16. Volume and Growth Predictions for Thinned Even-Aged Natural Longleaf Pine Stands in the East Gulf Area

    Encouraged by the high quality and marketability of longleaf pine (Pinus palustris Mill.), many landowners are taking advantage of recent improvements in longleaf regeneration techniques (Mann 1969, 197O; Croker and Boyer 1975; Farrar and White 1983; Dennington and Farrar 1983) and are growing longleaf pine today. Successful longleaf timber management demands...

  17. A comparison of dynamic and static economic models of uneven-aged stand management

    Numerical techniques have been used to compute the discrete-time sequence of residual diameter distributions that maximize the present net worth (PNW) of harvestable volume from an uneven-aged stand. Results contradicted optimal steady-state diameter distributions determined with static analysis. In this paper, optimality conditions for solutions to dynamic and static...

  18. Crown releasing of red maple poles to shorten high-quality sawlog rotations

    The effects of six crown-release treatments on growth and bole quality development of 54-year-old dominant, codominant, and intermediate red maples (Acer rubrum L.) were evaluated on a good red maple site (site index = 19.3 mat 50 years) in upper Michigan. Results showed that crown release stimulated the growth of dominants, codominants, and strong...
