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...
Remote sensing technologies have proven useful and cost-efficient for quantifying various forest vegetation characteristics over multiple scales. However, significant limitations were encountered in each of two related experiments conducted to explore their potential to supplement or replace traditional, single-species biomass equations for estimation of ground vegetation and tree overstory on...
