  Citation × Citation Citation Abstract Copy Title: A physical and chemical characterization of stream water draining three Oregon Coast Range catchments Author: Hale, V. Cody Few studies have examined both long-term and fine-scale spatial variations in water quality of small streams in the Pacific Northwest. As such, a case study was conducted to determine if current physical and chemical properties of water in three streams located in the Oregon Coast Range differed from historically measured conditions, taking differences in past management regimes into account. In addition, this research provides an assessment of spatial and temporal variability in nitratenitrogen (N) concentrations and summer stream temperatures within each catchment. The three research catchments were part of the Alsea Watershed Study (1959- 1973), where effects of forest management practices were examined using a pairedwatershed study design. One catchment, Needle Branch, was clear-cut with no protection provided to the stream. Harvesting in Needle Branch was followed by an intense broadcast burn to remove logging slash. Another catchment, Deer Creek, was patch-cut in three small units resulting in a 25% harvest of the total catchment area, but buffers were retained along fish-bearing streams. The third catchment, Flynn Creek, was used as a control. In this revisit to the Alsea Watersheds, measurements were conducted continuously (discharge, turbidity), intermittently (suspended sediments), and at regular intervals (nitrate-N) for one year between October 2005 and September 2006. Summertime stream temperature was also measured every half-hour from mid-June to mid-September. Comparisons of recent data with historic data show no detectable changes over time for streamflow characteristics (annual runoff volume, peak flow discharges, and number of low-flow days), annual sediment yield, or summer maximum stream temperatures. Current nitrate-N export was similar to historically measured values for Flynn Creek and Deer Creek; however, export at Needle Branch was increased over past levels. This observation may be caused by dense colonization of the riparian area with red alder (Alnus rubra), a N-fixing species, following the 1966 harvest. Patterns of nitrate-N concentration varied throughout each catchment and are likely influenced by the current distribution of red alder stands. Synoptically measured stream temperatures were variable along each stream’s longitudinal profile. The ability to meet Oregon’s water quality standard for temperature was dependent on measurement location and method of analysis. Evaluating individual sampling points as discrete records resulted in each stream exceeding the standard for at least one measurement location, whereas evaluating the criteria based on the mean of all data collected within the mainstem stream excluded Flynn Creek and Needle Branch from violation. These results highlight the physical and chemical variability of stream water draining Oregon Coast Range headwater catchments and provide insight as to where future work should be focused to gain a more thorough understanding of these dynamic systems.

  Citation × Citation Citation Abstract Copy Title: Coarse woody debris in streams of the Drift Creek Basin, Oregon Author: Veldhuisen, Curt N. This study examined the occurrence of coarse woody debris (i.e., pieces greater than 0.15 m in diameter and 2.0 m in length) in first- through fifth-order streams located within the Drift Creek Basin of the Oregon Coast Range. Nine "tributary reaches" were surveyed to determine how three land management treatments (undisturbed, patch clearcut with buffer strip, and entirely clearcut) and/or geomorphology were associated with CWD loadings or piece characteristics. An additional 45 km of third- to fifth-order channels were surveyed to identify CWD distribution patterns over changing stream size. All surveys recorded channel characteristics and the dimensions and attributes of each CWD piece. Coarse woody debris loadings varied greatly (11 to 62 pieces/lOOm, 0.3 to 4.3 m³/100m² of inchannel volume) between the tributary reaches, but were not significantly (p > 0.10) related to harvest treatment. However, reaches associated with clearcut treatment contained less hardwood CWD and pieces were significantly shorter, and more decayed than in the other treatments. This suggested that little CWD recruitment had occurred in the 15 to 20 years since harvest. The undisturbed and buffer strip tributaries contained CWD that reflected continued recruitment of both hardwood and conifer trees. Inchannel CWD loadings averaged 0.44 m³/100m² and decreased significantly (p < 0.01, r² = 0.68) with drainage area. Coarse woody debris frequency and total loading averaged 10 pieces/lOOm and 14 m³/lOOm, respectively, and were not significantly related to stream size. The percentage of total CWD volume within the channel increased with stream order and decreased with increasing channel gradient. "Large" debris pieces (i.e., pieces greater than 0.5 m in diameter and 10 m in length) were particularly frequent in the gorge-like reaches of the Drift Creek Wilderness. Over one third of the CWD pieces in larger channels occurred within debris jams. Coarse woody debris loadings in the Drift Creek Basin appear to be lower than other forested streams in the Pacific Northwest. It is concluded that past stream cleaning, harvesting, and basin geomorphology have influenced CWD loadings within the Basin. However, the effects of nineteenth century forest fires on stand characteristics and debris recruitment trends appear to be a major cause of the observed CWD loadings.

  Citation × Citation Citation Abstract Copy Title: Riparian vegetation in Oregon's western Cascade Mountains : composition, biomass, and autumn phenology Author: U.S. International Biological Program. Coniferous Forest Biome, Campbell, Alsie Gilbert, Franklin, Jerry F. Sixteen understory plant communities in the riparian zones of small streams are identified and described. They range from pioneer communities on gravel and rock to well-developed shrub communities on flood plains and terraces. Several other vegetation types are discussed. Distribution of communities within the riparian zone is also discussed. A survey of nine small streams shows the Acer circinatum community to have the widest distribution and highest cover, but the Rubus spectabilis/Ribes bracteosum community is somewhat more common in the active zone. Biomass estimates are made for riparian vegetation along three stream segments. Total foliar production for 1976 is calculated for all vegetation, for communities, and for individual species. The percentage of each type of foliage which may reach the stream directly, indirectly, or not at all is estimated. Abscission and fall senescence for thirteen species was monitored. Leafy and herbaceous detrital input is timed. Rates of leaf fall and decadence are related to environmental factors.

The Lamprey Eel Decline project conducted by the Confederated Tribes of Siletz Indians (CTSI) combined traditional ecological knowledge, scientific research and geographic information science. CTSI wanted to learn why the Pacific lamprey (Lampetra tridentata), a culturally and ecologically important species, was declining in the streams within their native land area. The project included interviewing native elders, characterizing stream habitat, monitoring water quality, creating a geographic information system (GIS) and educating tribal members on the cultural and ecological importance of the Pacific lamprey. Dynamic segmentation, a GIS data structure, was used to link standard stream survey data on the river unit scale to a base stream coverage (1:24,000). Dynamic segmentation efficiently associates georeferenced data to a linear feature, thus allowing the data to be readily assessable on desktop computer systems. To be more useful to the tribal and local resource managers, it is recommended that these GIS coverages of aquatic habitat should be used in conjunction with additional data coverages and basic regional models for watershed analysis and better management of aquatic ecosystems.

  Citation × Citation Citation Abstract Copy Title: Biology and distribution of the Dicosmoecinae (Trichoptera: Limnephilidae) in western North America Author: Wisseman, Robert William Literature and museum records have been reviewed to provide a summary on the distribution, habitat associations and biology of six western North American Dicosmoecinae genera and the single eastern North American genus, Ironoquia. Results of this survey are presented and discussed for Allocosmoecus, Amphicosmoecus and Ecclisomvia. Field studies were conducted in western Oregon on the life-histories of four species, Dicosmoecus atripes, D. failvipes, Onocosmoecus unicolor and Ecclisocosmoecus scvlla. Although there are similarities between genera in the general habitat requirements, the differences or variability is such that we cannot generalize to a "typical" dicosmoecine life-history strategy. A common thread for the subfamily is the association with cool, montane streams. However, within this stream category habitat associations range from semi-aquatic, through first-order specialists, to river inhabitants. In feeding habits most species are omnivorous, but they range from being primarily detritivorous to algal grazers. The seasonal occurrence of the various life stages and voltinism patterns are also variable. Larvae show inter- and intraspecific segregation in the utilization of food resources and microhabitats in streams. Larval life-history patterns appear to be closely linked to seasonal regimes in stream discharge. A functional role for the various types of case architecture seen between and within species is examined. Manipulation of case architecture appears to enable efficient utilization of a changing seasonal pattern of microhabitats and food resources.
