APPENDIX II 



Data Input for Program TREM0D1 



Codes for species, habitat type, etc., are defined in a BLOCK DATA subroutine that 

 can be readily modified. Definitions and units for other variables such as the index 

 age for site only need to agree with the corresponding variables used in the growth 

 models . 



Data cards needed: 



#1 § 2) The stand information format cards. These will contain the format 

 (enclosed in parentheses) needed to read in the variables on card #7. 



#3 S 4) The tree record format cards. These will contain the format (enclosed in 

 parentheses) needed to read in the variables on card #8. 



#5) Contains the following variables: 

 Variable Coliams Type and forfnat 



NPLT 8-15 Alphanimeric 2A4 



NCYC 16-18 Integer 13 



IY(J) 19-21,22-24, Integer array 



2013 



#6) Contains the following variables: 

 Variable Columns Type and format 



8-15 Alphanumeric 2A4 



ALPH 

 CTN(J) 



Definition 



Stand identification 



Maximum number of cycles 



The excess of the calendar year over 1900 

 for successive projection cycles for 

 J=l,. . . ,NCYC+1. 1900 + IY(1) = year of 

 initial inventory. 



Definition 

 Stand identification 



16-20,21-25, Real array 11F5.0 Residual stand density to be left after 



thinning at the start of each projection 

 cycle. (If CTN(J) equals or exceeds the 

 stand density, no thinning will be per- 

 formed. )
