Paired 30-day trials were conducted to evaluate
Agropyron spicatum germination when treated with two
concentrations of throughfall leachates from western
juniper slash in two stages of decomposition. Data from
a second pair of 49-day greenhouse trials were analyzed
to evaluate emergence and growth of Aqropyron spicatum,
Oryzopsis hymenoides, and Poa...
Ranchers and resource managers have become concerned about the
role and spread of Cardaria draba (L.) Desv. (whitetop) in the sagebrush
steppe of Northeastern Oregon. This area is an important natural resource
for livestock production and big game winter range.
An area near Keating, Oregon was selected to study the...
A natural resource science education program for members of the Warm Springs
Indian Reservation was designed and developed in partnership with tribal members. The
intent of the project was to create a culturally relevant program supported by culturally
reflective educational materials which met local needs. The goal of the project...
The purpose of this research was to determine if
overland flow and sediment production were different in
logged (on snow, frozen soil, and prescribed skid trails)
and nonlogged sites in a Pinus ponderosa Laws.!
Symohoricaroos albus Laws. community in the foothills of
the Wallowa Mountains in northeastern Oregon. To determine...
Reforesting harvested lands in southwestern Oregon has been
difficult because of low rainfall, high evaporative demand, and
competitive understory vegetation. Herbicides have been a preferred
method to control competing vegetation but herbicide use on federal
lands was curtailed in 1984. As a result, interest in livestock
grazing as a vegetation...
A case study was performed in 2000 and 2001 to characterize the thermal pattern of four morphologically similar eastern Oregon streams and to identify the physical and environmental factors that expressed significant and functionally viable relationships with stream temperature (daily maximum, daily minimum and daily rate of heating). Stream and...
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...
