The effects of prescribed burning on the rates of recent litter
decomposition, nitrogen and phosphorus release from litter, soil total and
inorganic nitrogen pools, and net nitrogen mineralization were determined in
ponderosa pine sites that had been burned 0.3, 5 or 12 years earlier. Prescribed
burning decreased litter decomposition rates...
Tree growth and soil nutrient responses to prescribed underburning were determined for a period of up to 12 years at four sites in northcentral and central Oregon ponderosa pine stands (Pinus ponderosa Dougl. ex Laws).
Differences reported are significant at a = 0.10. During the first 4-growing-season-measurement period after
underburning,...
A series of stereo photographs displays a range of residue loadings for cleancut units in three general forest types common to coastal Oregon forest lands: Douglas-fir--western hemlock (second-growth), western hemlock--Sitka spruce, and red alder. Postburn residue levels are also represented for the Douglas-fir--western hemlock, and red alder types. Information with...
I conducted two separate studies, both related to the impacts of spring and fall prescribed fire on ponderosa pine (Pinus ponderosa Dougl. ex Loud.) forest soils in Eastern Oregon. The studies were either conducted at or linked to four stands of ponderosa pine, in the Malheur National Forest. Each stand...

Decline of western sage grouse (Centrocercus urophasianus phaios)
in Oregon may be related to the reduced availability of foods in upland
sagebrush (Artemisia)-grasslands used for brood-rearing. The goal of
this study was to determine primary foods of chicks and the short-term
response of brood-rearing habitat to prescribed burning at Hart...

Stands of brush and tree species of low commercial value dominate many potentially productive forest lands in western Oregon. Site preparation to reduce competition from such vegetation will improve the success of reforestation efforts, as well as reduce the cost of controlling small mammals that destroy seeds and seedlings. Site...
The vegetation response of spring and fall prescribed fires in basin big sagebrush (Artemisia tridentata subsp. tridentata Nutt.)/Idaho fescue (Festuca idahoensis Elmer)--bluebunch wheatgrass (Agropyron spicatum Pursh. (Scribn. & Smith)) communities was measured at the John Day Fossil Beds National Monument in eastern Oregon. Objectives of the study were to quantify...

We compared the potential fire behavior and smoke production of historical and current time periods based on vegetative conditions in forty-nine 5100- to 13 500-hectare watersheds in six river basins in eastern Oregon and Washington. Vegetation composition, structure, and patterns were attributed and mapped from aerial photographs taken from 1932...
Prescribed burning is increasingly being used as a management tool to reduce potential fuels on the forest floor and promote stand vigor through removal of dense, crowded vegetation. Because fire affects both the standing vegetation and the amount of downed wood in the ecosystem, it is imperative to examine how...
Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...
Three data sets were examined to determine the costs with and without
constrained forest management practices. Two adjacent sites in the Coast Range of
Oregon were studied. One of the units was broadcast burned while the adjacent site was
left unburned. The stands were projected for growth and yield in...
