TIGER for Estimating Basis (TIGER EB) is a computer program that can help estimate the basis (value of the trees in a woodland at the time of purchase) by simulating growing trees in a current inventory back in time and use their estimated sizes and number of trees per acre to estimate the value of the trees in a woodland at the time of purchase.  Basis is often used to reduce the taxes to be paid from income from timber harvests, but of course, you need to consult your tax advisor about estimating your basis.

  The program uses the same growth models as TIGER WC, ones developed by the US Forest Service.

 

A detailed manual has been prepared for the program, and a quick-read version.  There is one version for both manuals that apply to all states.  

You will need to buy TIGER for Woodlands and Compartments to create the data files that the Basis program reads.
