  • Effect of western juniper removal on ponderosa pine and associated understory vegetation

    Creator:
    Rose, Jeffrey A.
    Abstract:
    This research assessed the effect of western juniper (Junlperus occldentalls) removal on understory plant production and cover and ponderosa pine (Pinus ponderosa) growth and plant water status. A complete randomized block design, with four blocks and four treatments was established in the summer of 1984 near Prineville, Oregon. The four...

  • Modeling riparian zone processes : biomass production and grazing

    Creator:
    Korpela, Edwin J.
    Abstract:
    Seasonal trends in forage production and environmental parameters for five plant community types within a northeastern Oregon riparian zone were described and modeled using correlation and path analysis. Wet meadows produced the greatest amount of herbage biomass, followed by moist bluegrass meadows, gravel bars, forests and dry bluegrass meadows. Trends...

  • Understory competition for resources in Pinus ponderosa forests of northeastern Oregon

    Creator:
    Riegel, Gregg M.
    Abstract:
    The objective of this research was to determine which environmental resources, light, water, and nutrients, control understory plant production and composition in a Pinus ponderosa forest in northeastern Oregon. A split-plot experimental design, with three blocks, four treatments, and 44 plots, was established in the summer of 1985. Twenty plots...
