Quaking Aspen - Seed Germination And Early Seedling Growth, United States Department Of Agriculture, Forest Service Jan 1979

Quaking Aspen - Seed Germination And Early Seedling Growth, United States Department Of Agriculture, Forest Service

Forestry

The suckering of aspen (Populus tremuliodes Michx.) as a highly effective means of vegetative propagation is well known and has been widely studied (Baker 1918; Day 1944; Maini 1967; Schier 1974). Less is known about seed propagation, sometimes viewed as having only minor importance because early research (Baker 1918) had indicated that rare seedling establishment was due to low or nonexistent germinability.


Nutrient Losses From Timber Harvesting In A Larch/Douglas-Fir Forest, United States Department Of Agriculture, Forest Service Jan 1979

Nutrient Losses From Timber Harvesting In A Larch/Douglas-Fir Forest, United States Department Of Agriculture, Forest Service

Forestry

Nutrient levels as a result of experimental clearcutting, shelterwood cutting, and group selection cutting--each with three levels of harvesting intensity--were studied in a larch-fir forest in northwest Montana, experimentally logged with a skyline system. None of the treatments altered nutrient levels in an intermittent stream, nor were excessive amounts of nutrients lost in soil below the root zone. Under conditions on this site, skyline logging did not result in surface erosion or nutrient losses that would affect forest management.


Fire - Decay: Interactive Roles Regulating Wood Accumulation And Soil Development In The Northern Rocky Mountains, United States Department Of Agriculture, Forest Service Jan 1979

Fire - Decay: Interactive Roles Regulating Wood Accumulation And Soil Development In The Northern Rocky Mountains, United States Department Of Agriculture, Forest Service

Wildfires

Decay and fire play interactive roles in recycling wood and other organic materials in forest ecosystems, and contribute to the development of high quality soils in the Northern Rocky Mountains. Decayed wood, charcoal, and other decomposed organic matter are the principal media for ectomycorrhizal and nonsymbiotic nitrogen fixing microbes. The activities of these microbes are critical to the growth of forest trees. The balance between decay and fire, as it affects the amount, distribution, and type of organic matter, controls the ability of forest soils to support the growth of trees.

Stochastic Analysis For Water Quality, Ronald F. Malone, David S. Bowles, William J. Grenney, Michael P. Windham Jan 1979

Stochastic Analysis For Water Quality, Ronald F. Malone, David S. Bowles, William J. Grenney, Michael P. Windham

Reports

This report demonstrates the feasibility of applying stochastic techniques to linear water quality models. The Monte Carlo, First Order, and Generation of Moment Equation techniques are applied to a long term phosphorus model of Lake Washington. The effect of uncertainty of the phosphours loading term on simulated phosphous levels is analyzed. All three stochastic techniques produced the same results. The simulated concentrations of phosphorus in the water column are very responsive to uncertainty in annual phosphorus loading, the sediment concentrations relatively insensitive. The Monte Carlo technique is shown to require the most computation time of the three stochastic techniques applied. …
