  • Field study of competition between medusahead (Taeniatherum caput-medusae ssp. asperum (Simk.) Melderis) and squirreltail (Elymus elymoides (Raf.) Swezey)

    Creator:
    Clausnitzer, David
    Abstract:
    Medusahead (Taeniatherum caput-medusae ssp. asperum (Simk.) Melderis) is a Eurasian annual grass that infests large areas of U.S. rangelands, dominating former bunchgrass/shrub sites. Squirreltail (Elymus elymoides (Raf.) Swezey) is a native perennial grass that has demonstrated the ability to establish in stands of medusahead. A study conducted on two sites...

  • Assessment of impacts of Canada geese on wheat production

    Creator:
    Louhaichi, Mounir
    Abstract:
    Numbers of wild Canada geese (Branta canadensis) have increased dramatically during the past 30 years in the lower Columbia and Willamette Valley systems. The damage they cause by grazing and trampling plants can be substantial. The objectives of this research were to: 1) Develop methods that provide reliable estimates of...

  • Methods to assess factors that influence grass seed yield

    Creator:
    Louhaichi, Mounir
    Abstract:
    A greater than 10-fold increase in Canada goose (Branta canadensis) populations over the past several years has resulted in concerns over grazing impacts on grass seed production in the mid-Willamette Valley, Oregon. This study was designed to develop methods to quantify and statistically analyze goose-grazing impacts on seed yields of...

  • Elevation, thermal environment, and stream temperatures on headwater streams in northeastern Oregon

    Creator:
    Meays, Cynthia L.
    Abstract:
    A case study examining the relationship between stream temperatures and the thermal environment through which streams flow was conducted on the headwaters of 4 tributaries of the Burnt River (Barney, Elk, Greenhorn, and Stevens Creeks) in northeastern Oregon during July through August 1998 and 1999. Barney Creek and Stevens Creek...

  • Describing the thermal regimes of two northeastern Oregon streams

    Creator:
    Raven, Sonja E.
    Abstract:
    Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied during the summers of 2000 and 2001 to determine water heating and cooling patterns. Hourly temperature data were recorded for air, water, and soil parameters at four elevations 150m apart on Barney and Stevens Creeks....
