Challenges to Gray Wolf Recovery in Washington, Oregon, and Northern California

Creator:: Kriz, Matthew A.
Abstract:: Gray wolves (Canis lupus) are the most socially polarizing species listed under the Endangered Species Act. Wildlife management practices at local, state, and federal levels include lethal control to resolve stakeholder and wolf conflicts as a last resort. There is little experimental evidence that lethal control is effective in this...

Sustaining Bend's Urban Forest: An assessment of the City's urban forest management approach and recommendations for future adaptations

Creator:: Lex, Mitchell
Abstract:: The City of Bend’s current urban forest management strategy consists of a series of city codes and ordinances, tree protection and planting standards, and two different plans created by the Bend Park and Recreation District. The analysis of these documents, as well as review of existing management approaches in Boise,...

Wood density of young-growth western hemlock: relation to ring age, radial growth, stand density, and site quality

Creator:: DeBell, Dean S., Singleton, Ryan, Gartner, Barbara L., and Marshall, David D.
Abstract:: Breast-high stem sections were sampled from 56 western hemlock (Tsuga heterophylla (Raf.) Sarg.) trees growing in 15 plots representing a wide range of tree and site conditions in northwestern Oregon. Growth and wood density traits of individual rings were measured via X-ray densitometry, and relationships of ring density and its...

Land-use in the Willamette Valley from 2004-2017

Creator:: Strimbu, Bogdan M., Mueller-Warrant, George, and Trippe, Kristin
Abstract:: The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

Predicting height for undamaged and damaged trees in southwest Oregon

Creator:: Hanus, Mark L., Hann, David W., and Marshall, David D.
Abstract:: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for various tree species common to southwest Oregon. Data for damaged and undamaged trees were analyzed with weighted nonlinear regression techniques. The effects of specific damaging agents and their severity on the height-diameter...

Height-diameter equations for six species in the coastal regions of the Pacific Northwest

Creator:: Hanus, Mark L., Marshall, David D., and Hann, David W.
Abstract:: Three equations for predicting tree height as a function of diameter (outside bark) at breast height are presented for six species found in coastal regions of the Pacific Northwest. Foresters can use these “height–diameter” equations to avoid the time-consuming task of measuring heights of all individual trees in an inventory,...

Predicting height to crown base for undamaged and damaged trees in southwest Oregon

Creator:: Hanus, Mark L., Hann, David W., Marshall, David D., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage...

Reanalysis of the SMC-ORGANON equations for diameter-growth rate, height-growth rate, and mortality rate of Douglas-fir

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing data from untreated research plots, we developed equations for predicting 5-yr diameter-growth rate (ΔD₅), 5-yr height-growth rate (ΔH₅), and 5-yr mortality rate (PM₅) for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in the coastal region of the Pacific Northwest. These equations are revisions of the equations constructed in 1995–1997 for...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...

Tarif tables for mountain hemlock developed from an equation of total stem cubic-foot volume

Creator:: Bell, John F., Marshall, David D., Johnson, Gregory P., and Oregon State University. Forest Research Laboratory
Abstract:: Tarif access tables were developed for mountain hemlock [Tsuga mertensiana (Bong.) Carr.] on the Deschutes National Forest in the Central Oregon Cascade Mountains from an equation for cubic-foot volume including top and stump (CVTS). These tables provide access to the comprehensive tree-volume tarif system.
