The response of soils, streambanks and instream coliform bacteria levels to grazing management in a riparian area

Creator:: Bohn, Carolyn C.
Abstract:: This thesis describes a case study of the effects of five systems of grazing on watershed values in a deteriorated riparian area. Soil infiltration, bulk density and penetrability, streambank edge movement and coliform bacteria were monitored for seven years along a stream in the Blue Mountains of northeastern Oregon. For...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...

Application of nonequilibrium ecology to managed riparian ecosystems

Creator:: Stringham, Tamzen K.
Abstract:: Seasonal trends in water table level and soil moisture for four plant community types within an irrigated eastern Oregon riparian zone were described. Aboveground biomass, species composition, litter, percent bareground and percent basal cover of key plant species and life forms were measured. The relationship between water table levels and...

Riparian and wetland vegetation of central and eastern Oregon

Creator:: Crowe, Elizabeth A. (Elizabeth Ann), 1963-, Kovalchik, Bernard L., Kerr, Marie Jeannette James, 1968-, Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: The structure and components of riparian areas influence the rate, amount, and timing of water, nutrients, organic debris, and inorganic materials that enter streams and rivers. The energy of floodwaters and their ultimate volume, timing and erosive power is influenced by the soils, vegetation and geomorphology of fluvial surfaces within...

Coarse woody debris in streams of the Drift Creek Basin, Oregon

Creator:: Veldhuisen, Curt N.
Abstract:: 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...

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...

A characterization of unmanaged riparian overstories in the central Oregon Coast Range

Creator:: Nierenberg, Tara R.
Abstract:: Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian overstories in the central Oregon Coast Range along nine streams which have experienced minimal disturbance...

Relations among hydrology, soils, and vegetation in riparian meadows : influence on organic matter distribution and storage

Creator:: Dwire, Kathleen A.
Abstract:: Organic matter dynamics in riparian ecosystems are largely driven by interactions among hydrology, soil, and vegetation. In two riparian meadows, northeast Oregon, I examined the hypothesis that vegetation and soil characteristics in three plant communities - defined as wet, moist, and dry meadow - were strongly influenced by hydrological and...

Estimating large woody debris recruitment from adjacent riparian areas

Creator:: Minor, Kathleen P.
Abstract:: Large woody debris recruitment to streams from adjacent riparian forests influences stream channel morphology, sediment routing, and fish habitat. A mathematical model was developed to 1) determine whether the trees in a stand adjacent to a stream, upon falling, would provide large woody debris of a specified size to the...
