  	Citation × Citation Citation Abstract Copy Title: Typical salmon stream Year: 1925 This slide represents a typical salmon stream in which a few salmon may be observed ascending the river. A very interesting controversy has arisen over what is known as the "parent stream" theory. In years past it has been debated pro and con in a lively fashion. There are those who have contended that adult salmon ascend the stream in which they were hatched and which their parents ascended. According to this idea, some instinct is supposed to have a directive influence upon the fish as they approach maturity, drawing them into the river which they descended a few years before. For support of this contention it is pointed out that marked fish released as fry in a certain river have been taken in the same stream when adult. There is no denial on the part of those who oppose the "parent stream" theory that salmon are often taken as adults in the same stream in which they were hatched. In fact, this is only to be expected. Our knowledge concerning the salmon during their existence in the ocean is necessarily very limited. It is believed, however, that salmon do not go very far distant from the mouths of rivers which they descended, or that they confine their migrations during the period of growth to near-shore waters up and down the coast. When the period of maturity nears after a few years in the ocean, the salmon being near the mouths of rivers come in contact with the fresh waters of the streams that flow into the ocean with considerable force. The salmon are attracted by this current and make their way into the mouths of the rivers and begin the ascent of the streams. It is only natural that some may find their way into the same rivers which they descended three or four years before. It is believed by the better authorities that the "parent stream" phenomenon is explained as a natural result of the habits of the fish while in the sea. Salmon are taken for commercial purposes in many ways. It is only to be expected that in the case of fish so valuable as the salmon many devices would be employed for their capture. One of the methods of taking the salmon is by the fish wheel, as is illustrated by slides.

  Citation × Citation Citation Abstract Copy Title: Keying forest stream protection to aquatic ecosystem values in multi-ownership watersheds Author: Pickard, Brian R. Forested lands of western Oregon provide aquatic habitat for many fish and riparian dependent species, including a wide variety of salmon species. Current policies set riparian protections using fixed buffers on streams for federal and private lands based on stream type or size. These buffers can create a series of disjointed riparian protections, as federal lands require buffers that are much larger than private lands. In addition, the fixed buffer approach is neither flexible nor tailored to aquatic ecosystem values. This thesis presents a framework for comprehensively assessing stream networks using site specific watershed features and then suggests riparian conservation strategies that key stream and riparian protection to aquatic ecosystem values. Seven study watersheds were used in this analysis, totaling over 2.5 million acres of forested lands in western Oregon. Employing a set of geospatial tools, called NetMap, streams in each watershed were classified into higher and lower priorities using criteria of intrinsic potential, erosion/debris flow susceptibility, and thermal loading potential. Results demonstrated the inherent variability within and among watersheds based on the geomorphic and ecological processes determined important for selected salmon species. Within each watershed, both federal and non-federal lands had many miles of higher priority fish-bearing and non-fish bearing streams, suggesting the need for comprehensive, holistic watershed conservation strategies. Based on the partitioning of streams into higher and lower priorities, an alternative riparian conservation strategy was then modeled for federal lands that allocate protection on the basis of the ecological context of a stream segment’s potential and particular location while still meeting federal aquatic conservation goals and objectives. Possible increases to the land base for long-term timber production were then identified if this strategy were applied to federal Matrix lands. Results demonstrated that 8-30 percent of the current riparian buffers could be reallocated to the land base for long-term timber production. An additional 26-45 percent of current buffers could be managed simultaneously for both timber production and aquatic ecosystem goals. Results also provided a framework for targeting of conservation and restoration efforts towards higher priority streams within each watershed. As many of the most ecologically important streams were located on non-federal lands, riparian conservation policies focused on streams classified as higher priority on those lands may be needed to protect aquatic species and their environments.
