The influence of tree cover and shade pattern upon the distribution of understory plants in ponderosa pine stands of central Oregon

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Seven sites of uniform topography and soil were selected within a self perpetuating ponderosa pine forest found on the eastern flank of the central Oregon Cascades. These plots were located along a vegetational gradient caused mainly by an orographic rain shadow. Data gathered included density, frequency, and cover for all...

The relationship of non-recovered rodent caches to the natural regeneration of ponderosa pine

Creator:: Saigo, Barbara Woodworth
Abstract:: Studies were conducted within a 12-mile radius of Camp Sherman, Oregon, in the Deschutes National Forest during the spring and summer of 1965 and the spring of 1966, with one follow-up visit in the summer of 1967. The feeding and foraging activities of Eutamias amoenus and Citellus lateralis were observed,...

Spatial and chronological patterns of Purshia tridentata as influenced by Pinus ponderosa overstory

Creator:: Sherman, Robert James
Abstract:: Twelve sites of uniform topography and soils were selected in the Pinus ponderosa/Purshia tridentata/Festuca idahoensis Association. These sites were located in the rain shadow on the east flank of the Oregon Cascades. A fire history in the form of fire scars on ponderosa pine was available for nine of these...

Fungitoxicities of NaMDC decomposition products to decay fungi colonizing Doulgas-fir and ponderosa pine wood

Creator:: Canessa, Edwin
Abstract:: Metham sodium or NaMDC is one of the four major soil fumigants that are currently registered for controlling internal decay of wood products in use. Fumigants are used primarily in utility poles but are also applied to piling, timbers and other large wood members. NaMDC must decompose to fungitoxic compounds...

Inner Bark Utilization : A Nez Perce Example

Creator:: Churchill, Thomas E.
Abstract:: Ponderosa pine trees exhibiting large oval scars on their trunks are found in northeastern Oregon. Patterns in the occurrence and morphology of the scarred trunks raise questions of archeological interest. Examination of ethnographic sources from the Pacific Northwest indicate that the bark of ponderosa pine was peeled to obtain the...

Age structure and spatial pattern of old-growth ponderosa pine in Pringle Falls Experimental Forest, central Oregon

Creator:: Morrow, Robert J.
Abstract:: The dynamics of stands In old-growth ponderosa pine (Pinus ponderosa) forests on the eastern flank of the central Oregon Cascades are Investigated. Age structure and spatial pattern of ponderosa pine within the Pringle Falls Experimental Forest Research Natural Area coupled with the fire history of the area aid In Interpreting...

The effects of mechanical and chemical site preparation on ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex Loud.) performance, associated vegetation, and soil properties in southcentral Oregon eight years after planting

Creator:: Ross, Darrell W.
Abstract:: The effects of six alternative site preparation treatments were compared at three different sites in southcentral Oregon. Treatments included a logged-only control, ripping, brushblading, disking, chemical, and chemical followed by disking. Subplots containing ponderosa pine bareroot (2+0) and containerized (1+0) and lodgepole pine containerized (1+0) seedlings were also included in...

Phytosociology of the ponderosa pine type on pumice soils in the Upper Williamson River Basin, Klamath County, Oregon

Creator:: Volland, Leonard A.
Abstract:: The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...

An analysis of peripheral milling of finger-joints in ponderosa pine cut-stock

Creator:: Liu, Yongsheng
Abstract:: To make low grade lumber into high-valued products, finger-jointing is a widely used method in the timber industry. In certain situations, chip-out occurs degrading the quality of the joint. To better understand the machining process, a beam-type dynamometer based on strain gages was designed to analyze the dynamic cutting forces...
