Tarif access tables : a comprehensive set

Creator:: Bowers, S. (Steven Clay), Coleman, Nate, and Oregon State University. Extension Service
Abstract:: Tarif access and tree volume tables in this publication are for Douglas-fir, grand fir, ponderosa pine, red alder, western hemlock, and western redcedar. Tarif numbers range from 15 to 60, allowing you to estimate virtually any tree volume for the listed species, based on diameter at breast height (DBH) and...

Tools for measuring your forest

Creator:: Bowers, S. (Steven Clay) and Oregon State University. Extension Service
Abstract:: Woodland owners routinely want to measure property acreage, boundaries, ground slope, various characteristics of standing timber, and individual log volumes. Different tools are required for each of these tasks.

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...

Stand volume and growth : getting the numbers

Creator:: Bowers, S. (Steven Clay), Coleman, Nate, Fletcher, Richard A., and Oregon State University. Extension Service
Abstract:: The procedures outlined in this publication show you how to estimate standing volume and annual growth of timber stands—areas that are uniform in age, stand characteristics, and species. Estimates of volume and growth are helpful in planning when to harvest or how much to remove in a thinning operation. These...

Measuring timber products harvested from your woodland

Creator:: Oester, Paul T., Bowers, S. (Steven Clay), and Oregon State University. Extension Service
Abstract:: This publication describes measurements used to buy and sell timber products. Managing woodland property offers you the opportunity to harvest a variety of products, depending on timber quality and quantity, harvest economics, and market availability. Among these products are saw logs, peeler logs, pulpwood, fuelwood, poles, piling, and posts. Knowledge...

Enhanced height-growth-rate equations for undamaged and damaged trees in southwest Oregon

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr height growth rate of a tree are presented for six conifer species from southwest Oregon. Equations for the combination of undamaged and damaged trees were estimated with weighted nonlinear regression techniques. These equations are being incorporated into the new southwest Oregon version of ORGANON, a...

Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

Creator:: Eskelson, Bianca N. I.
Abstract:: The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

An investigation of factors affecting the optimal output log distribution from mechanical harvesting and processing systems

Creator:: Marshall, Hamish Douglas
Abstract:: Globally the forest harvesting industry is becoming increasingly mechanized. Driving this trend is the desire to increase productivity and reduce cost, as well as to improve labor-related issues. With mechanization comes an in-forest platform for the introduction of state-of-the-art communication and measurement technologies, and powerful on-board computers. These systems have...

Enhanced diameter-growth-rate equations for undamaged and damaged trees in southwest Oregon

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr diameter-growth rate of a tree are presented for eight conifer and nine hardwood tree species from southwest Oregon. Equation parameters for undamaged and damaged trees combined were estimated by weighted nonlinear regression. The resulting equation for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] explained more than 71%...

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...
