Tools woodland owners need to measure property acreage, boundaries, and characteristics of standing timber, including individual log volumes, are described.
Tarif numbers are essential for calculating the volume of standing timber on forest land. This publication includes comprehensive tarif numbers for six species of Oregon timber--Douglas-fir, grand fir, ponderosa pine, red alder, western hemlock, and western redcedar--and the corresponding tree volumes.

Selling timber by the tree or by the thousand board feet is a
business proposition. Both the seller and the buyer must know the
quality and the quantity of the products being sold.

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...
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.
One of the most important challenges facing foresters is the
development of a raw material measurement system designed to give
a complete inventory of log volume and to assist in planning the complete
management of log production. This paper introduces a concept
of production analysis in terms of solid fiber...
This study was a test of eight basal area factors and five point
sampling cluster patterns in a computer oriented sampling study of
coastal Alaska old-growth spruce-hemlock stands. It was an attempt
to learn which basal area factor and which type of point sample cluster
pattern should be used in...
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...
This study was initiated to determine the accuracy and limits
of the height-accumulation method of measuring tree volume and
surface area for Pacific Northwest second-growth trees. Thirty
trees were selected from various thinning treatments in a 55 year
old Douglas-fir forest. Each tree was measured with the highly
accurate Barr...
