| Abstract | Transportation is one of the major problems facing the entrepreneur in the lumber industry. Bryant (1913) hypothesized that the “transportation of forest products to mill or market represents 75% or more of the total delivered cost of raw material, exclusive of stumpage value.” Log transportation and stumpage acquisition and value are still the two major costs before the mill processes. Logs have always been considered a heavy, bulky, and cheap commodity that could not stand expensive transportation charges. Those successful in the lumber industry had to become specialists in transporting logs over the long distances that separated the primary producer from the consuming market. Indeed, the transportation of logs is still one of the central pivots around which success or failure of a lumbering operation revolves. In the past, transporting the logs inexpensively was the industry’s biggest concern. Only in the last decade has the concern for aquatic or coastal marine environments been a main consideration. In earlier days, river navigation and sawmill waste resulted in environmental changes that are still detectable. Present environmental concerns over log handling in coastal waters are well documented for intertidal areas but less so for subtidal environments. 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 habitat losses and the volumes of logs transported by water, both fresh water and marine. Many changes in stream-channel structure and evidence of habitat simplification still exist today, nearly 100 years after river-driving activities have ceased. The current perspectives on British Columbia and southeastern Alaska, as well as on a few locations in Oregon and Washington, draw extensively on excellent summaries, reviews, and task-force reports from both Canada (Duval et al. 1980) and the USA (Hansen et al. 1971). The objectives of this chapter are to review and describe historical log transportation in rivers, which was extensive in the western USA and eastern British Columbia; to provide perspectives on the volume of logs transported and areal extent of the estuarine and river habitats allocated to log transfer and storage; and to describe the environmental effects of log transfer and storage that relate to fish habitats. |
