Fire ecology of ponderosa pine and the rebuilding of fire-resilient ponderosa pine ecosystems

Creator:: Fitzgerald, Stephen Arthur
Abstract:: The ponderosa pine ecosystem of the West have changed dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a grange of 49-124 trees per ha (20-50...

Methods for multi-spatial scale characterization riparian corridors

Creator:: Moser, Thomas J., Lindeman, Dale R., Wigington, P.J., Schuft, Michael, and Van Sickle, John
Abstract:: 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...

Effect of riparian areas on the ecological condition of small, perennial streams in agricultural landscapes of the Willamette Valley : research plan, June 1997

Creator:: Moser, Thomas J., Wigington, P.J., Schuft, Michael J., Kaufmann, Phillip R., Herlihy, Alan T., Van Sickle, John, and McAllister, Lynne S.
Abstract:: 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...

Vegetation characterization of three contrasting riparian areas : Williamette Valley, Oregon

Creator:: McAllister, Lynne S., Dwire, Kathleen A., and Griffith, Stephen M.
Abstract:: 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...

The biology and external morphology of bees ; with a synopsis of the genera of northwestern America

Creator:: Stephen, William Procuronoff, 1927-, Bohart, George Edward, and Torchio, Philip F.
Abstract:: ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...

Inorganic chemistry of water and bed sediment in selected tributaries of the South Umpqua River, Oregon, 1998

Creator:: Hinkle, Stephen R. and Geological Survey (U.S.)
Abstract:: This report presents results of an investigation of water and streambed-sediment quality in selected tributaries of the South Umpqua River. Concentrations of inorganic constituents in water (major and minor ions, nutrients, and trace elements) and streambed sediment (primarily trace elements), along with standard field parameters, are tabulated for samples collected...
