stream metabolism to investigate the effects of timber harvesting under current Louisiana BMPs. In this study we monitored continuous dissolved oxygen (DO) concentrations over a four-year period in a 2nd-order, forested headwater stream with a low-gradient channel, rich organic substrate, and frequent stagnant by: Long-term timber harvesting effects still need to be explored. This study demonstrates that through measurements of stream DO, which is a single point-in-time measurement on its own, the effects of timber harvesting on in-stream biological processes can be investigated. More work is needed to standardize what metabolic rates constitute “impaired”, especially in the slow-moving and high organic matter-containing streams Cited by: Cite this chapter as: Stednick J.D.

Ecosystem-based timber harvesting uses methods that _____. leave seed-producing or mature trees uncut to provide for future forests Forests reach their greatest ecological complexity when ________.
Post hoc analysis of the one-way ANOVA model assessing the effect of riparian buffer on distance from the stream showed that the Control 1 and 30 m sites did not differ, nor did the 0 m or 9 m sites differ, but all comparisons between these groups were significant, showing that at the 0 m and 9 m sites salamanders were found closer to the by: Results showed that timber harvest caused significant decreases in the color, turbidity, temperature, pH, and electrical conductivity values of the stream water and air temperature under the. ENVIRONMENTAL EFFECTS OF TIMBER HARVEST AND UTILIZATION OF LOGGING RESIDUES By Marlin C. Galbraith* INTRODUCTION Publicity about environmental problems has done for forestry . harvests, stream flow began to return to preharvest levels. However, the trees retained in the buffer zone increased their collective water use after harvest, and at least partially offset the hydrologic effects of the timber harvest. Ultimately, underlying geology and soil type had a stronger influence on stream discharge than tree water-.
