This book was released on 2011 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Powerdale Dam was an 87-year-old hydroelectric complex on lower Hood River in northern Oregon which was decommissioned in 2010. Macroinvertebrate samples were collected in 2009, before the removal process began, and in 2010, near the end of the demolition project, at one site upstream and three sites downstream of the dam. Macroinvertebrate communities were analyzed using both multi-metric (Benthic Index of Biotic Integrity [B-IBI]) and multivariate (Predictive Assessment Tool for Oregon [PREDATOR]) approaches, as well as EPT and Functional Feeding Group (FFG) analysis. All analytical approaches indicated declines in habitat quality in 2010 relative to 2009, and showed increasing impairment in the downstream sites in 2010, with sediment implicated as an impairment factor. Pollutants such as pesticides released from the impoundment might also contribute to downstream disturbance levels. The upstream, control site showed habitat quality declines in 2010 relative to 2009, indicating a possible upstream source of impairment. The demolition project did not physically impact upstream areas, and tributary turbidity does not appear to have been elevated relative to other years; however, the Hilsenhoff Biotic Index indicates an increase in upstream nutrient pollution in 2010 relative to 2009. Future research will be able to establish rate and extent of post-removal habitat recovery relative to these baseline data.

Download or read book Place based Learning for the Plate written by Joel B. Pontius and published by Springer Nature. This book was released on 2020-06-08 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume explores 21st century stories of hunting, foraging, and fishing for food as unique forms of place-based learning. Through the authors’ narratives, it reveals complex social and ecological relationships while readers sample the flavors of foraging in Portland, Oregon; feel some of what it’s like to grow up hunting and gathering as a person of Oglala Lakota and Shoshone-Bannock descent; track the immersive process of learning to communicate with rocky mountain elk; encounter a road-killed deer as a spontaneous source of local meat, and more. Other topics in the collection connect place, food, and learning to issues of identity, activism, spirituality, food movements, conservation, traditional and elder knowledge, and the ethics related to eating the more-than-human world. This volume will bring lively discussion to courses on place-based learning, food studies, environmental education, outdoor recreation, experiential education, holistic learning, human dimensions of natural resource management, sustainability, food systems, environmental ethics, and others.
