The Past, Present, and Future of Fire and Ponderosa Pine Stand Dynamics in the Metolius Research Natural Area, Central Oregon

Creator:: Johnston, Kayla M.
Abstract:: The Metolius Research Natural Area (RNA), located 29 km northwest of Sisters, Oregon, was originally established in 1931 to maintain a ponderosa pine (Pinus ponderosa Dougl. Ex Laws) and dry, mixed-conifer forest with the aim to meet objectives of preserving natural conditions, providing for research opportunities, and preserving gene pools...

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...

Recruitment of ponderosa pine seedlings beneath partial overstories

Creator:: Keyes, Christopher R.
Abstract:: The objective of this project was to investigate the fate of ponderosa pine regeneration from seed to established seedling, and to determine the relative influences of several important stand elements on those fates. The project was carried out in a series of observational and experimental recruitment studies in central Oregon....

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...

Morphological characteristics of ponderosa pine and lodgepole pine regeneration nine years after stand density reduction at three sites in central Oregon

Creator:: Michel, Alexa K.
Abstract:: Without the natural occurrence of fire in ponderosa pine forests of the western US, lodgepole pine has started to dominate regeneration in many forest stands and may be gradually replacing ponderosa pine over time. This development, however, conflicts with recent efforts in this region to restore old-aged, open ponderosa pine...

Soil-site productivity relationships of central Oregon ponderosa pine

Creator:: Wilson, Duncan Steil, 1969-
Abstract:: The relationship between annual foliage production and nitrogen and water stress was examined in 14 naturally regenerated, mid-rotation ponderosa pine stands in central Oregon. Current-year and older foliage masses, and foliage nitrogen contents and concentration were estimated from 132 destructively sampled trees. Litterfall mass and nitrogen retranslocation rates from senescing...

Tree Vigor Response and Competitive Zone Density in Mature Ponderosa Pine

Creator:: Shaw, Randi C.
Abstract:: This study explored the relationship of mature ponderosa pine (Pinus ponderosa Dougl. ex Laws) tree vigor and competitive zone density following thinning and fuel reduction treatments. Competitive zone density (CZD) was defined as the total tree basal area (m²/ha) surrounding a given ponderosa pine tree within a 10m fixed radius...
