Jeffery, Olsen, Anthony R., Schreuder, Hans T., National Health and Environmental Effects Research Laboratory (U.S.) An interagency project demonstrated the feasibility of integrating Federal surveys of terrestrial natural resources and offers a vision for that integration. At locations selected from forest inventory and analysis, National forest system Region 6, and national resources inventory surveys in a six-county area in Northern Oregon, experienced teams interpreted and made measurements on aerial photographs and measured on-site a range of soil, vegetation and animal attributes. The project demonstrated the feasibility of conducting a combined FIA/NFS/NRI survey at the substate level and suggests an approach that will preserve the utility of the critical historic information from these surveys.

  Citation × Citation Citation Abstract Copy Title: Effect of riparian areas on the ecological condition of small, perennial streams in agricultural landscapes of the Willamette Valley : research plan, June 1997 Author: Moser, Thomas J., Schuft, Michael J., Wigington, P.J., Herlihy, Alan T., Van Sickle, John, Kaufmann, Phillip R., McAllister, Lynne S. 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.

Six high-use destination areas were studied in the Alpine Lakes, Mount Jefferson, and Three Sisters Wildernesses in Washington and Oregon. Exit interviews were conducted with visitors, and recreation impacts and visitor encounter rates between groups were quantified. Encounter rates were extremely high and impacts were substantial but localized. Visitors were more concerned about high impact levels than high encounter rates. Management implications are explored.

This was the first year that extensive monitoring of forest vegetation for ozone injury was carried out in Oregon, and Washington. Injury was detected on ponderosa and Jeffrey pine in the Sierra Nevada permanent plots and on red elderberry at one FHM location in southwest Washington. 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.

  Citation × Citation Citation Abstract Copy Title: Small scale photo probability sampling and vegetation classification in southeast Arizona as an ecological base for resource inventory Author: Johnson, James Russell Increasing demands on earth resources require the need to know how much resource is present. A new technology, which is developing partially with the support of the National Aeronautics and Space Administration, will help to inventory and monitor surface resources in a more comprehensive manner than previously possible. Research in southeastern Arizona for the past six years has been developing methodology that would permit the use of space and high altitude imagery for natural vegetation and related resource investigations. This paper reports on three meaningful research contributions in remote sensing of natural vegetation. They are (1) a natural vegetation classification suitable for remote sensing use, (2) a technique for objectively comparing space imagery for relative information content, and (3) a sample scheme for using small scale photography to identify and estimate areas of vegetation types. The natural vegetation classification contains 31 "vegetation types" that were developed for a 3, 200 square mile area. The types are ecologically determined from association tables, and are, therefore, suitable for use in remote sensing applications. This is possible primarily because the types are related to photo identifiable landform variables. The classification is suitable for generalized levels of land use planning, but this was not tested. Three types of space imagery were evaluated for apparent photographic information content. The technique avoided subject-image relationships by concentrating directly on image characteristics. The approach, coined "image groupability", should be a worthwhile contribution to the larger problem of comparative imagery interpretations. An example demonstrates an approach to objective photo stratification based on image groupability results. The third accomplishment involved design and execution of a comparative two stage sampling scheme to estimate kind and extent of vegetation types. The comparison was between two space photos substituted at the first sampling stage. At the second stage (high altitude photography) potential secondary sampling units were categorized by image similarity rather than by the more complicated process of ground subject interpretations. Efficiency gains from space photo stratification were not substantial; however, the sample scheme was effective. Furthermore, clustering, a space photo sampling artifact, saved an estimated 32-35 percent in "working time" expenses when making ground checks by helicopter.
