ent ages (usually in lo-year periods) per unit of area (usually per 

 acre) . 



Normal yield tables are constructed separately for given species on 

 different sites (and sometimes different growth regions) under <li: 

 treatment, and are used as standards with which to compare actual 

 yields. The statements of a normal yield table are derived as an 

 average from the best producing areas. If a normal forest were not 

 only an idea, but actually attainable, the normal yield table would 

 represent its productivity and stock. 



Empirical yield table is a statement of the actual volumes of given 

 stands. They are of local value only. Since there is no " experience " 

 involved, the term Local yield table would be preferable. 



In finance, volumes may be translated into values and referred to as 

 money yield table, income table, or financial yield table.
