Predicting logging debris accumulation in natural streambeds : a method for forest managers

Creator:: Hess, Vernon Scott
Abstract:: This study has analyzed factors which affect the accumulation of terrestrial organic debris within natural gravel streambeds. In addition, the amounts, sizes, and physical conditions of intruded material were measured, along with the effect of the detritus on intragravel dissolved oxygen levels. Measurements indicate that aged intragravel detritus had no...

Atmospheric trace element abundances associated with slash burning

Creator:: Ungerer, Carl Andre
Abstract:: The atmospheric trace element abundances associated with slash burning have been measured by instrumental neutron activation analysis (INAA). On site ground level samples were collected during the slash burning season using high volume samplers and a cascade impactor. In addition to the air samples, soil, wood and ashed wood samples...

Natural debris and logging residue within the stream environment

Creator:: Lammel, Richard Friedrich
Abstract:: Amounts of natural debris in small headwater streams under old growth stands of Douglas-fir vary from 6 1/2 tons per 100 ft. of stream to 26 tons per 100 ft. of stream, depending on terrain and timber characteristics and sequence in the natural accumulation-flushing cycle. Approximately 10% of the weight...

Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

Creator:: Ursitti, Victoria L.
Abstract:: Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...

Spatially-explicit prediction of recoverable harvesting residues

Creator:: Schmidt, Christian F. W.
Abstract:: In order to decide whether or not to develop biomass energy facilities and where to best locate them, developers and investors need accurate assessments of fuel supply. This includes information about the distribution and concentration of fuel throughout the assessment area, the quality of fuel (form, moisture content, contaminant content,...

The intrusion of logging debris into artificial gravel streambeds

Creator:: Garvin, William Fredrick
Abstract:: The objective of this study was to quantitatively describe the intrusion of logging debris into artificial gravel streambeds during conditions of low stream flow with a stable streambed, and begin an analysis of the effect of high flow and unstable streambeds. This study was initiated because prior studies indicated that...

Recruitment trends and physical characteristics of course woody debris in Oregon Coast Range streams

Creator:: Heimann, David C.
Abstract:: This study investigated the long-term consequences of timber stand removal on the recruitment, physical characteristics, and spatial distribution of coarse woody debris in small (second- and third-order) streams of the Oregon Coast Range. A chronosequence of stream-stand systems, ranging from 21- to 140-years since disturbance (YSD), were sampled to determine...

Modeling the impact of logging debris on the dissolved oxygen balance of small mountain streams

Creator:: Berry, John David
Abstract:: Previous research has indicated that considerable amounts of finely divided slash accumulate in small mountain streams following timber harvesting. The subsequent biological decomposition of this organic matter can result i.n the reduction of dissolved oxygen (DO) concentration to levels as low as 0.6 ppm. These DO levels are lethal to...

Response of needle-litter decomposition and soil nitrogen mineralization to logging-debris manipulation and competing vegetation control in western Oregon and Washington

Creator:: Meehan, Nathan Andrew
Abstract:: Growing societal demand for forest products is pressuring managers to increase productivity from a finite land area, and it is expected that increased supply will come mostly from expansion of intensively managed stands. The USDA Forest Service and numerous collaborators created the Long-Term Soil Productivity (LTSP) network of research sites...
