Timber
Cruises are statistical samples of a timber stand that allow us
to determine the amount of merchantable standing timber, usually
in Board-Foot units. The more sampling done on the timber stand,
the more accurate the results. I design, and execute, timber cruises
to acheive just the level of accuracy needed by the client, after
discussing their needs. Timber cruises can range from simple occular
estimates, using a method that I've verified the accuracy on, to
cruises that will produce a report acceptable to the timber industry,
typically, with a 10%, or lower, Standard Error.
I
can also collect the timber stand growth information needed for
the California NTMP or to support growth models.
My
cruise and scale reports document my method, along with the results,
and I include the raw field data, so that the client can have my
work reviewed by a third party or build on my sample later on, if
desired.
Log
Scaling. Like timber cruises, log scales sample quantities of down
or decked logs. These samples are typically more accurate than timber
cruises.
Both
my timber cruise and log scale sample designs can determine volumes
by log sorts and grades, preferrable if the intent is to market
the logs to a specialty market, such as the far eastern import market.
Further, I specialize in providing cruise & log scale samples
that can determine hardwood lumber
grades.
