Creator:: Mainwaring, Douglas B.
Abstract:: Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa and lodgepole pine stands in central Oregon. Basal area growth was modeled as a function of other stand and tree variables to address five general objectives: 1) to compare the predictive ability of distance-dependent versus distance-independent stand...

Abstract:: A pandora moth (Coloradia pandora Blake) outbreak began in 1991 in a ponderosa pine (Pinus ponderosa Dougl. ex. Laws) spacing study area that also included scattered sugar pine (P. lambertiana Dougl). The relation of defoliation to five tree spacings (with and without understory vegetation) was examined, and stand growth reduction...

Creator:: Kerr, Kelly L.
Abstract:: Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...

Abstract:: This thesis examines the 8-year growth trend of Douglas-fir (Pseudotsuga menziesii (mirb.)Franco), ponderosa pine (Pinus ponderosa Dougl. ex laws.), and whiteleaf manzanita (Arctostaphylos viscida Parry). Manzanita stands ranging from 1700/ha to 27000/ha density were grown among mixed conifers of the same age, which were planted in 1981 at 250x250 cm...
