   Table 2. Verification/validation table for species known via FIA to be 
   present in more than 100 counties, and with an IV at least 3.0. 
   [PF= number of  counties present in FIA data only; PP= number of 
   counties present in predictive model only; PB= number of 
   counties present in both; CA= classification accuracy 
   (PB/(PB+PF+PP)*100); EOA= error of omission accuracy (PB/(PB+PF)*100); 
   CORR= correlation between actual and predicted IV.
