  Citation × Citation Citation Abstract Copy Title: Quantifying physical habitat in wadeable streams : surface waters Author: Robison, E. George, Seeliger, Curt, Levine, Paul, Peck, David V., Kaufmann, Phillip R. We describe concepts, rationale, and analytical procedures for characterizing physical habitat in wadeable streams based on raw data generated from methods similar or equal to those of Kaufmann and Robison (in PB99-139156). We provide guidance for calculating measures or indices of stream size and gradient, sinuosity, substrate size and stability, habitat complexity and cover, woody debris size and abundance, residual pool dimensions and frequency, riparian vegetation cover and structure, anthropogenic disturbances, and channel-riparian interaction. We evaluated sampling precision of field habitat survey methods employed by EMAP in several hundred streams in Oregon and the Mid-Atlantic region, comparing variance among streams ('signals') with variance between repeat stream visits (measurement 'noise'). The final measure of the utility of a habitat approach is whether it is useful for interpreting controls on biota or impacts of human activity.

The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The focus is on fine grained remote methods. Comparison between candidate selected monitoring systems provides for an initial formulation of a monitoring design. A series of evaluations of these initial formulations provides for an initial recommendation. With the state's interest in the status of coastal fishes, and the programmatic interest of EPA's Western Ecology Division, the areas selected for study are in the Oregon coastal province and the Willamette basin.

Little research has been directed toward determining the status and ecological role of riparian areas in agricultural landscapes of the Willamette Valley, Oregon. A research project has been designed to contribute to the development and evaluation of alternative future scenarios and to improve the basic understanding of the role of riparian areas on the ecological condition of small, perennial streams in agricultural landscapes of the Willamette Valley. The objectives of the research are: (1) to quantify relationships between riparian attributes at varying spatial scales and stream ecological condition, and (2) to estimate the influence of selected riparian area-agricultural configurations on the indicators of stream ecological condition. To address these objectives, remotely-sensed imagery (aerial photography and thematic mapper satellite imagery) will be used to quantify land cover at multiple spatial scales (i.e., stream reach, stream network, watershed), from which riparian vegetation function, land use stressor, and stream network structure indicators (i.e., potential explanatory variables) are derived for 41 study watersheds.

  Citation × Citation Citation Abstract Copy Title: Ecological functions of off-channel habitat, Willamette River, Oregon : final research plan Author: Sharps, D., Cline, S.P., Landers, Dixon, Andrus, Charles W., Erway, M.L. Off-channel features such as alcoves and side channels can have important ecological functions for large rivers such as the Willamette River. Some species and age classes of fish may select these features instead of the main channel to feed, avoid predation by other fish, escape fast water, or seek out cool water in the summer. Other organisms such as amphibians, mussels, and birds may also be attracted to alcoves and side channels because of unique physical and water quality characteristics. This proposal describes research to evaluate the functions of alcoves and side channels in a large river ecosystem, determine factors that currently affect their ecological functions, and identify future management actions that could be taken to improve these functions. In addition, the authors intend to relate the processes occurring within alcoves and side channels to processes occurring in the main channel, in adjacent ground water, and the riparian vegetative community.

Forest Service, National Applied Resource Sciences Center (U.S.), Borman, Michael M., Elsbernd, Van, Leonard, Steve (Stephen G.) This document presents information from various land managers and researchers to guide livestock management in riparian areas using their unique responsiveness to accomplish management objectives. Riparian areas, as interfaces between the aquatic and upland components of the ecosystem comprise mosaics of landforms, communities, and environments within the larger landscape. The structure and processes of riparian areas, more than any other ecosystem, are influenced by their connectivity to adjacent ecosystems. An ecosystem perspective provides an ecological basis for evaluating current grazing practices and other land uses, identifying riparian management objectives, and developing future management alternatives.

  Citation × Citation Citation Abstract Copy Title: Vegetation characterization of three contrasting riparian areas : Williamette Valley, Oregon Author: McAllister, Lynne S., Dwire, Kathleen A., Griffith, Stephen M. Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and restoration planning. The objective of this study was to characterize the vegetation of three contrasting riparian sites occurring in the Willamette Valley. W determined plant species composition and abundance at a non-cultivated herbaceous site and a cultivated site, both located along Lake Creek, an intermittent stream, and at a forested site located along the Calapooia River, a perennial stream. All sites were adjacent to intensively-managed perennial ryegrass seed production fields. Crop agriculture strongly encroached on the Lake Creek sites, whereas the Calapooia site had received little encroachment from agricultural coversion. At Lake Creek, we inventoried 32 species at the non-cultivated herbaceous site and 18 species at the cultivated site, most of which were non-native. The cultivated site was dominated by wetland-adapted species in the area closest to the creek where perennial ryegrass was absent. Approximately half of the species at the non-cultivated herbaceous site were facultative upland species, and the site was dominated by introduced pasture grasses. In contrast, the 53 species inventoried at the forested site were mostly native and wetland-adapted. The forested site was dominated by Poplus balsamifera ssp, trichocarap T. & G., Pseudotsuga menziessii (Mirbel) Franco, and Acer macrophyllum Pursh, with extensive shrub and herbaceous strata. Results show a range of vegetative conditions found in riparian areas of the Willamette Valley and reflect the influence of differing hydrologic regimes and agricultural impacts.

  Citation × Citation Citation Abstract Copy Title: Fire history and pattern in a Cascade Range landscape Author: Swanson, Frederick J., Pacific Northwest Research Station (Portland, Or.), Morrison, Peter H. Fire history from years 1150 to 1985 was reconstructed by analyzing forest stands in two 1940-hectare areas in the central-western Cascade Range of Oregon. Serving as records for major fire episodes, these stands revealed a highly variable fire regime. The steeper, more dissected, lower elevation Cook-Quentin study area experienced more frequent fires (natural fire rotation = 95 years) that were commonly low to moderate in severity. The Deer study area, with its cooler, moister conditions and gentler topography, had a regime of less frequent (natural fire rotation = 149 years), predominantly stand-replacement fires. Fires created a complex mosaic of stands with variable date and severity of last burn. Fire-created forest patches originating in 1800-1900 are mostly less than 10 hectares. Since 1900, very little of the study areas burned, possibly because of fire suppression.

The prescriptions emphasize alternative approaches for joint production of North American matsutake mushrooms (also known as North American pine mushrooms; Tricholoma magnivelare) and high-quality timber. Other agroforestry byproducts from the system are ornamental conifer boughs, pine cones, and Christmas trees. Management practices concentrate on increasing the physiological efficiency and vigor of trees, and on altering leaf area index, tree species composition, and stand age-class structure to increase matsutake reproduction. Programs of thinning and branch pruning test regulating flows of energy and moisture to mushroom mycelia in the upper soil.

No injury was detected at the Mount Rainier sites. The authors also report on results of a trial where red alder, huckleberry, blue elderberry, and chokecherry were exposed to ozone under controlled conditions. Close

This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused on assessing riparian-stream systems in agricultural landscapes of Oregon's Willamette Valley, GIS land cover/land use databases were created from 1997 aerial photography and digital orthophotography for 23 predominantly agricultural watersheds, including detailed land cover-land use coverages within 150 m of perennial and intermittent streams. GIS functions were used to partition the stream networks at various lateral-longitudinal scales to quantify land cover/land use and to generate functionally relevant metrics of riparian vegetation, such as its composition, width, and continuity. The methods developed provide considerable flexibility for generating metrics characterizing attributes of riparian corridors and for exploring relationships among these metrics and indicators of stream ecological condition.

  Citation × Citation Citation Abstract Copy Title: Growth and yield of western larch under controlled levels of stocking in the Blue Mountains of Oregon Author: Cochran, P.H. Repeated thinning to five growing-stock levels resulted in widely differing tree sizes and volumes per acre after 30 years. Largest trees but the least cubic-volume yield per acre were produced in the heaviest thinning level, whereas highest board-foot yields were found in intermediate thinning levels. partial defoliation by larch casebearer (Coleophora Iaricella Hubner), drought, and top damage from ice occurred, and site trees grew less in height than expected during the 30-year study. Curvilinear increases in periodic annual increments of both basal area and cubic volume generally occurred with increasing stand density, but increments dropped off at the highest stand densities for some periods. Anticipated patterns for these increments were found after fitting a model that included stand density index, height increments of site trees, and dummy variables for periods as independent variables. heavy thinning did not increase the age of culmination of cubic-volume means annual increment as expected. Thinning stands of larch to densities as low as 50 percent of 'normal' results in little loss of basal-area growth, a moderate loss in volume production, and a large increase in tree diameter. Thinning is necessary in many larch stands to maintain vigorous, rapidly growing trees.

  Citation × Citation Citation Abstract Copy Title: Reconnaissance of Noatak National Preserve and Biosphere Reserve as a Potential Site for Inclusion in the Integrated Global Background Monitoring Network Author: Wiersma, G. Bruce, McKee, Arthur, Slaughter, Charles, Hilgert, Jerry, Halpern, Charlie The report presents results of the initial reconnaissance effort of a pilot study to assess the suitability of Noatak National Preserve (also a designated UNESCO/MAB International Biosphere Reserve) as a site for an Integrated Global Background Monitoring site. Sites currently established as part of the pilot network are Olympic National Park, Washington, USA, and Torres del Paine National Park, Chile. Objectives of the global network are: to establish reference levels for pollutants that already exhibit global contamination; establish baseline measurements of ecosystem parameters that permit comparison of more impacted areas; and serve as an early warning system for detecting increases in hazardous pollutants and changes in ecosystem processes. Because of its remote and pristine nature, Noatak National Preserve appeared to be an excellent candidate for inclusion in such a baseline network.
