Simultaneous equation estimation for individual tree growth in young Southern Oregon and Northern California conifer plantations

Creator:: Hamann, Jeff D.
Abstract:: This thesis presents methods for obtaining asymptotically efficient and consistent parameters and variance estimates for simultaneous equations in a forest growth modelling context. Ordinary Least Squares (OLS), Seemingly Unrelated Regressions (SUR), Two-Stage Least Squares (2SLS) and Three- Stage Least Squares (3SLS) are presented for linear models. The variables, model types...

Temporal effect of vegetation management on growth and wood quality of conifers in a western Oregon plantation

Creator:: Goracke, Heidi S. Roe
Abstract:: Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and duration of vegetation control on wood quality near the pith...

Growth analysis of heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

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...

Alterations in Douglas-fir crown structure, morphology, and dynamics imposed by the Swiss needle cast disease in the Oregon Coast Range

Creator:: Weiskittel, Aaron R.
Abstract:: Plants respond to defoliation in many different and complex ways, depending on their growth habit and form as well as the extent and duration of the defoliation. Tree crowns have been shown to be quite sensitive to disturbances such as defoliation, however quantitative relationships have rarely been developed, making the...

Crown structure, stand dynamics, and production ecology of two species mixtures in the central Oregon Cascades

Creator:: Garber, Sean M.
Abstract:: Knowledge of stand structure, stand dynamics, and production ecology of species mixtures lags well behind that of single-species, even-aged stands. Two mixed-species spacing trials in central Oregon allowed investigation of mixed-species dynamics in a controlled experimental setting. The first site, Pringle Butte, is a mixture of ponderosa pine (Pinus ponderosa...

Growing stock assessment and growth prediction system for managed hill dipterocarp forest of Peninsular Malaysia

Creator:: Kassim, Abd. Rahman
Abstract:: The silviculture of mixed dipterocarp forests of Peninsular Malaysia can potentially be improved by developing quantitative tools and guidelines for this forest type. This thesis addresses three key objectives; 1) to test the hypothesis that a maximum size-density relationship can be identified in hill dipterocarp forests of Peninsular Malaysia, 2)...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...

An examination of several methods of quantifying forest structure in headwater riparian forests of western Oregon

Creator:: Haxton, Zane A.
Abstract:: Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...

The presence and characterization of measurement error in forestry

Creator:: Canavan, Sean Joseph
Abstract:: Measurement error (ME) is a component of any study involving the use of actual measurements, but is often not recognized or is ignored. The consequences of MEs on estimates of tree and stand attributes and the parameters and predictions of forest models can be varied and severe, including the presence...

Taper, crown, and volume responses of a coastal Oregon Douglas-fir stand to sulfur treatments for control of Swiss needle cast

Creator:: Younger, Nicole L.
Abstract:: For nearly two decades, foresters in the Oregon Coast Range have been witnessing a substantial decease in Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) vigor and growth, caused by Swiss needle cast (Phaeocryptopus gaeumannii). Currently, no solutions are in sight but aerially-applied sulfur may alleviate Swiss needle cast and its...

Using a heuristic programming method for incorporating wildlife habitat constraints into spatial harvest scheduling on the Elliott State Forest

Creator:: Lennette, Marie
Abstract:: The Elliott State Forest, located in the Coast Range of Oregon, is currently revising their Habitat Conservation Plan (HCP). Many of the constraints in the HCP are spatial, requiring identification of specific parcels in order to limit activity along habitat reserves, limit harvest opening size, and to coordinate activities within...

Forest industry restructuring and emerging forest tenures in Deschutes and Klamath Counties, Oregon

Creator:: Kelly, Erin Clover
Abstract:: Since the 1980s, industrial forest restructuring has resulted in the divestment of industrial timberlands across the U.S. Emerging tenures have benefited from the divestment, including conservation-based tenures that manage for multiple objectives such as restoration, recreation access, and forest and habitat contiguity. Deschutes and Klamath Counties, Oregon, have three proposed...

The SafeD model : incorporating episodic disturbances and heuristic programming into forest management planning for the Applegate River Watershed, southwestern Oregon

Creator:: Graetz, David H.
Abstract:: A hybrid landscape optimization/simulation model called SafeD (Simulation and analysis of forests with episodic Disturbances) was built to address the needs of forest management planning in the Applegate River Watershed, southwestern Oregon (the Apple gate Project). There are two goals of the Applegate Project: 1) search for forest policies and...
