printed if an insufficient niimber of trees within any species was sampled. 

 (See table 17). 



Size of Compartment . The size of each compartment in acres must be 

 specified. If not known exactly it must at least be estimated. 



Tally Forms and Product Specification 



Tally forms are available for use with INVENT (see Appendix A, page 46) . 

 Trees are tallied using a two letter species code (Appendix A, page 45), 

 diameter class, height and product . The product column is used as follows: 

 INVENT allows trees to be graded as sawlog or pulpwood. If you do not wish 

 to grade trees simply ignore the product column and all trees will be assumed 

 sawlog. If you do wish to grade trees there are two methods available. You 

 can grade the entire tree as sawlog or pulpwood by entering an S in the product 

 column for sawlog, or entering a P for pulpwood. Alternatively, you may spec- 

 ify the percent sawlog in the tree. If you put 60 in the product column, 60 

 percent of the volume will go into sawlog and 40 percent will go into pulpwood. 



The column marked # is used if two or more trees of the same species, size 

 and product are tallied on a given plot. 



Output Tables 

 Seventeen tables are presented as an example of INVENT 's output. Tables 

 1-16 are part of a 59 page inventory report based on a 3 compartment cruise 

 of Whitaker Woods in North Conway, N.H. Tables 1-9 are for compartment 1 

 while tables 10-16 are for all 3 compartments combined. Table 17 is taken 

 from another cruise where the height double sampling option was used. This 

 table is a summary of that relationship. The output tables are further dis- 

 cussed in section 3 on page 34. However, the tables should be self-explanatory 

 to most foresters.
