RICHER is a sophisticated interpolation routine which allows the user to
generate data for points he does not have. The following activities
are at best marginally legitimate.
A. Regenerate a dataset at a different step size (monthly points
instead' of bimonthly)
B. Estimate, missing data due to equipment failure
This study was initiated to determine the relative efficiency
of systematic, stratified and simple random sampling for crown area
and tree frequency estimation of five of the major forest types found
in the Pacific Northwest. Several of the more common methods of
estimating spatial distribution coefficients were evaluated. Finally
The focusing of public attention on the practices of forest managers has resulted
in the need for new tools to help explain the results of these practices. The traditional
tools of tables and graphs of numerical values require a significant investment in
learning the forestry profession. Once the investment is...
The Coniferous Forest Biome has access to several strip chart recorders but is definitely limited with respect to data-logging equipment. The methodology reported in this paper interfaces the common strip chart with the Coniferous Forest Biome Information bank storage system by
converting the strip chart data to card image data...
A dynamic programming algorithm (MS PATH) was used to develop a stand level optimization model, FPS Optimizer. The model incorporates a late-seral constraint on the profit maximizing objective function utilizing a four-descriptor structural index as a proxy. This index, the 'Old-Growth Index', rates the late-seral structural quality of a given...
Violations of one or more of the assumptions made In analysis of
variance (ANOVA) or linear regression analysis may lead to erroneous
results. Often data will not conform to the assumptions implicit in the
analyses, but transforming the data to a different scale may lead to an
appropriate model. Before...
This experiment was designed to investigate the use of volume
estimations from aerial photography and probability proportional to
size (PPS) sample selection in the development of a practical sampling
design for timber volume estimation on small land areas of
Pacific Northwest Douglas -fir (Pseudotsuga menziesii, Franco).
The major problem of...
