I used to contract for data processing with a program called FITSIM developed
by grad student Bo Mack at UMass back in the late 70's. For each tree you had
to record present grade and POTENTIAL grade.
You had to stand there and decide whether a tree would go from a grade 5 to a 4
or a 3 or a 2--for example--in a given time period. It was hard to figure for
trees that had some defect, but it was easy for those that didn't.
It produced real nice tables for growth and treatment simulations, with cut and
leave volumes and values according to the user's prescriptions, plus IRR and
That program made it off the mainframe to Bo's PC, but it never got to market
because he found better things to with his time than fiddle with a program that
maybe a couple dozen foresters would buy.
