Economic Contribution of the Forestry and Wood Processing Sectors in the State of Washington
(10/1/2009)Investment by value-adding wood industries is critical to sustaining forestland ownership. An increasingly complex array of forest owners and investors suggests a business climate that views forests as a financial, rather ... -
Economically Sustainable Working Forests:
(2005-10-24)Economic viability is an important part of the sustainability of working forests. With landowners facing increasing regulatory complexity, increasing demand for a diversity of forest outputs, and economic pressures to ... -
Economics and Salmon Habitat Conservation: Welcome to the Data-Poor Real World
(University of Washington Water Center, 2006-10-24)Benefit-cost analysis is as natural to economists as breathing—which sometimes gets us into trouble when we try to ply our trade in a data vacuum. In the data-poor real world, the practice of benefit-cost analysis often ... -
Ecosystem Services Markets
(2005-10-27)The term “ecosystem services” refers to indirect ecosystem functions such as water purification, flood control, carbon sequestration, climate regulation, and soil and nutrient cycling, as well as recreation or ... -
The Ecotoxicology of Mine Waste Contamination at Different Levels of Biological Organization in the Methow River Vally, Okanogan County, Washington
(Center for Water and Watershed Studies, 2003-05-15)A study of mine-waste contamination effects on Methow River habitat on the eastern slopes of the north Cascade Mountains in Washington state, U.S.A., revealed impacts at ecosystem, community, population, individual, ... -
Effect of Forest Harvesting and Riparian Buffers on Headwater Stream Temperatures
(University of Washington Water Center, 2010-02-17)Headwater streams are small in size, but can be 80% of stream length. They have a high density in steep terrain and have a high biodiversity of invertebrates, amphibians and fish. However, they are very sensitive to landscape ... -
The Effect of LiDAR Digital Elevation Model Resolution on Stream Network Prediction and Computational Requirements
(University of Washington Water Center, 2006-02-16)Mouton will describe his research into stream prediction. In his study, he examined the effects of digital elevation model (DEM) grid size for stream network predictions in the northwestern United States to test the accuracy ... -
Effectiveness of large woody debris in stream rehabilitation projects in urban basins
(Center for Urban Water Resources Management, University of Washington, 2000-03)In-stream rehabilitation projects are commonly built in response to problems that result from both local sources and diffuse watershed degradation. Local problems, such as an improperly sized culvert, are relatively ... -
Effects of Development on Coho Salmon and Implications for Stream Habitat Restoration
(University of Washington Water Center, 2009-03-31)Examination of a 20-year record of spawning coho salmon abundance from more than 80 streams in central Puget Sound indicated that even modest levels of development within a watershed were associated with reductions is ... -
Effects of Turbidity and Suspended Solids on Salmonids
(University of Washington Water Center, 2001-11)Human activities in Northwestern watersheds, including logging, grazing, agriculture, mining, road building, urbanization, and commercial construction contribute to periodic pulses or chronic levels of suspended sediment ... -
Efficacy and Potential for Non-Target Effects of Larvicides for West Nile Virus Control in Seatttle Catch Basin
(University of Washington Water Center, 2009-02-18)In anticipation of the spread of West Nile Virus, Seattle officials promoted a city-wide research effort over the summers of 2006 and 2007 designed to investigate the efficacy and fate of four common larvicides: Mosquito ... -
Efficacy and Safety of Reclaimed Water
(University of Washington Water Center, 2010-02-17)Brown will present a plan to develop a reclaimed water program in King County. She will discuss average water use and precipitation statistics. Next, she will consider the wildlife impacts of conventional discharges. To ... -
