Terrestrial laser scanning (TLS) may provide a way to increase timber value recovery by replacing manual timber cruising with a simple-to-use, cost-effective alternative. TLS has been studied in several trials worldwide. Past studies have not compared TLS based estimates with mill estimates of stem value and volume.

Two objectives of this research were to identify fungi which are
mycorrhizal with western hemlock and to examine the ecology of hemlock
mycorrhizal fungi indigenous to outplanting sites. Another objective
was to evaluate the effectiveness of mycorrhizal inoculation in
improving the performance of outplanted hemlock seedlings.
A list of over...
Inoculations of white fir, Shasta red fir, Douglas fir and
ponderosa pine with Pisolithus tinctorius spores when outplanted
failed to produce P. tinctorius mycorrhizae at the end of the first
growing season. In the third year a few P. tinctorius mycorrhizae
were formed on white fir. Inoculations reduced seedling survival...
The purpose of the study was to investigate the effect of trials-to-criterion on the retention of a discrete motor skill (overhand beanbag throw) by moderately mentally retarded and severely mentally retarded individuals. Nonmentally retarded individuals were involved as a control group. The subjects were grouped by degree of retardation and...
