      Stand name of up to 20 characters followed by the number of tree records
      in the description, the elevation, and a growth adjustment (an optional
      number of extra years to grow the standin the first period). (below) 

line 2

      Fifty-year site indices for each species.Site 
      index must be present for each species present. Zeros may be entered
      for species not present on the plot. 

line 3

      Breast-height ages for each species. Zeros may be entered if stand
      component is not even aged or if actual values are not known. Age is 
      a descriptive value only and is not needed for the simulations.

      Individual tree records follow, one per line. Each tree record has
      the following five items: species code, DBH in inches, total height 
      in feet, live crown ratio (decimal fraction), and the number of trees 
      per acre each tree record represents.
