Effects of logging on the spawning bed environment in two Oregon coastal streams. By. Abstract. Graduation date: The effects of two patterns of logging on the intragravel environment were studied in three Oregon coastal streams between June and June The watershed of one stream (Needle Branch) had been clearcut, and that of a. of the overstory on the aquatic environment of these watersheds are poorly understood. The Alsea Watershed Study began in Oregon in The objective of the study was to compare the effects of two patterns of logging on water quality and biological resources of small coastal streams. The study is scheduled for 15 years, with the first 7 years. and logging operations can increase the amount of fines; however, such increases may be temporary if high flows flush the gravels Key words: bed sediments, forest harvesting, Oregon Coast Range, sedimentation, spawning gravels, stream channels, water quality ADAMS, J.

Gravel bed conlposition in Oregon coastal by: The state Department of Environmental Quality says logging and other forest management work should not increase stream temperatures by more than degrees.

Oregon's failure to confront coastal pollution from logging, agriculture and other sources has cost the state $ million in federal grant money. Environmental effects of water transportation of logs in western North America can be divided into those caused by the historical driving of logs in rivers and streams and those due to the current dumping, rafting, and storage of logs in rivers and estuaries. The historical perspective focuses on . of the material eroded from headwaters areas. Studies of bed move-ment at Oregon State University (Klingeman, ) suggest that the porous gravels of our forest streams are also a "reservoir" for fine sediments. This material can interfere with spawning success for salmon and steelhead (Hall and Lantz, ). Soil Nutrients.

Oregon’s Department of Environmental Quality wrote a report that identified logging as a contributor to known risks for drinking water quality in communities up and down the Oregon coast. oregon Department of fish and Wildlife and the salmon Drift creek Watershed council. As the Northwest is known for forests, it is also known for salmon. The two are inextricably linked. Adult salmon, as well as steelhead, return from the ocean to spawn in forest streams that are sometimes small enough to . The Oregon Native Fish Status Report presents the results of the first statewide assessment of native fish populations in 10 years. This report will be used to help fish and wildlife managers identify priorities for developing conservation plans for at-risk native fish populations throughout the state.
