maple stands on the Allegheny Plateau of 

 northwestern Pennsylvania — stands that were 

 uncut or had been thinned one time. Grade 

 distribution is likely to be substantially dif- 

 ferent in stands that have been under inten- 

 sive management over a long period, or that 

 have been high-graded. 



Despite these limitations, the data are use- 

 ful for estimating stand value for typical 

 stands where specific grade information is 

 lacking. They can be used to estimate the 

 financial maturity of typical stands or to 

 evaluate short-term value changes that might 

 be expected from several cutting strategies in 

 typical stands. 



Stand values may be calculated from stand 

 table data by proportioning the trees in each 

 species-dbh class into grades. Tree value con- 

 version standards (Mendel et al. 1976) can 

 then be applied to derive a value for the en- 

 tire stand.
