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 salmon abundance. The fact that current zoning in this region directs nearly all future development into areas ...
What Does a Stream Ecologist Need to Know About Fatty Acids?
(University of Washington Water Center, 2008-02-26)
Brett will outline controls on zooplankton fatty acid content: 1) Taxonomic affiliation. 2) Diet. 3) Temperature. 4) Food ration/starvation. 5) Biochemical transformations. 6) Homeostasis.
Planning and Management of Forested Agricultural Riparian Buffers: the Case of the Skagit County Managed Agricultural Riparian Plantations (MARP)
(University of Washington Water Center, 2006-10-03)
Riparian forests are part of a complex and interconnected ecosystem that extends from the headwaters to the estuaries. This presentation describes elements of silvicultural systems for riparian buffers on agricultural lands in large floodplains of Northwestern Washington State. Riparian buffers protect and enhance aquatic ...
Buffer Strips and Tree Windthrow: Proglem or Habitat Enhancement?
(University of Washington Water Center, 2007-11-27)
Martin will discuss windthrow in buffer strips. He will compare the effects of logging to the effects of storm exposed landscapes. Next, he will ask: What are the effects of tree windthrow in buffer strips on fish habitat? What is the magnitude and duration of habitat change? Martin will present research that illustrates these ...
Stormwater and Salmon: Assessing the Ecological Impacts of Non-Point Source Pollution
(University of Washington Water Center, 2006-04-11)
Scholz will discuss one of the major threats to our oceans: non-point source pollution. He will discuss the effects of non-point source pollution on Pacific salmon.
A Tale of Two Rivers: or, It's a Long Way from Tiger Mountain to Topatopa Bluff
(University of Washington Water Center, 2007-05-29)
Booth will present a comparative analysis of Issaquah Creek (Washington) and Santa Paula Creek (California) watersheds. He will discuss these two watersheds, including their geological structures, hillslope stability, and erosion processes. He will also review measurement and prediction of sediment transport.
LiDAR-Based Metrics for Solar Energy Attenuation and Large Woody Supply Potential in Riparian Forests
(University of Washington Water Center, 2010-02-17)
Moskal will provide some background information about geospatial data and applications. She will review LiDAR based forest inventory and LAI (leaf area index) models. These models focus on large woody supply potential and solar energy attenuation. Finally, she will anticipate future work in the field.
Headwater Streams: How Much Protection Do They Need?
(University of Washington Water Center, 2007-02-14)
Edmonds will introduce the subject of headwater streams. He will review indicators of change. Next, he will describe two headwater studies in Washington State, and offer some concluding remarks.
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 of high-resolution LiDAR (Light Detection and Ranging) digital elevation data. He will describe the ...
Seasonal Changes in Structure and Salmon-Derived Biomass in the Macroinvertebrate Community of Kennedy Creek
(University of Washington Water Center, 2005-02-17)
Honea will ask the question: What is the effect of salmon spawning on the seasonal changes in aquatic macroinvertebrates? He will describe a study that measured macroinvertebrate characteristics in the Kennedy Creek in Washington State. He will compare upstream areas (no salmon) with downstream areas (with salmon) and describe ...
