PRODUCTIVITY OF RECENTLY CUT LANDS 



265 



mental data on species composition for the Pacific 

 Northwest was collected and tabulated under a 

 different concept. Here the species constituting 

 the stocking on the ground at the time of examina- 

 tion were recorded. In addition, field examiners 

 were required to determine the species constituting 



the stocking prior to logging by examination of 

 stumps and other available evidence. A com- 

 parison of the composition before and after logging 

 was prepared from these two sets of records and 

 is summarized in table 153. Data are presented 

 separately for clear cuttings and partial cuttings.
