I
have had lots of interest and questions on this topic. Well obviously it takes
a long time to become proficient in estimating the volume of timber on a tract
of land and I can not cover the topic in depth on this blog. However it is
worth talking about so you, the landowner has a general knowledge about the
topic. Cruising timber is actually a statistical exercise. The forester must
determine how many trees to actually count and measure to estimate the amount
of timber on a given tract of land. The practitioner walks through the woods
and takes sample plot at predetermined spots on the land. For the sake of
simplicity we will only discuss fixed area plots here i.e. if the forester
estimates how much timber is on that 1/10 acre plot, he simply mulitplies by 10
to estimate the total volume on that acre of land. Likewise this approach can
apply to a hundred acre tract or a thousand acre tract.
Next,
the trees he measures are converted to volume. Volume can be estimated in MBF
(thousand board feet), tons or cords. The following link show the various
volumes for comparison sake.
This is a very simplistic
approach to a complicated exercise, if you have specific questions, please
comment.
