Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major reasons for this are human caused changes to the environment, which continue to increase - in Oregon and throughout the world.
Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend on plant and animal products. About 50% of …
Since Time Immemorial: The Decline Of Columbia River Basin Salmon, Samuel J. Levin
Since Time Immemorial: The Decline Of Columbia River Basin Salmon, Samuel J. Levin
Young Historians Conference
Since Time Immemorial: The Decline of Columbia River Basin Salmon studies the near extinction of what has been historically the world’s largest salmon population. By examining the issue systemically, my paper reveals that the environmental misjudgments that have brought the salmon so near extinction are not isolated, but rather are the product of cultural trends. A study of these misjudgments reveals a culture within the Columbia Basin that has, since the mid-19th century, sought expansion for expansion’s sake and valued short-term wealth over long-term sustainability. My paper illustrates how his philosophy has guided and continues to guide Columbia Basin …

In 2006, a marked increase in harbor porpoise Phocoena phocoena strandings were reported in the Pacific Northwest of the USA, resulting in the declaration of an unusual mortality event (UME) for Washington and Oregon to facilitate investigation into potential causes. The UME was in place during all of 2006 and 2007, and a total of 114 porpoises stranded during this period. Responders examined 95 porpoises; of these, detailed necropsies were conducted on 75 animals. Here we review the findings related to this event and how these compared to the years immediately before and after the UME. Relatively equal numbers among …

Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major cause of this phenomenon is large-scale destruction of native habitats, which has increased since European settlement began in the mid 1800's - in Oregon and throughout the New World.

Irrigation, Power, And Salmon: The Case For Voluntary Water Transfers In The Columbia Basin, Eric Kuhner
Irrigation, Power, And Salmon: The Case For Voluntary Water Transfers In The Columbia Basin, Eric Kuhner
Center for Urban Studies Publications and Reports
This paper begins with a brief history of water law in the west, illustrating the roots of conflict over water allocation. A more detailed examination of activities in the Columbia Basin follows, describing the many parties affected by issues of water use and the overlapping institutional structures that govern the river and its water.
Sources of pressure to change the current pattern of water use are then considered. These include requirements to protect endangered salmon runs and the change over time in the relative values of water for power production and irrigation. This section demonstrates how changes in the value …
