The resurvey shows a larger reserved area than the initial survey. The 

 differences arise from refinements in survey techniques and definitions 

 for there has actually been little change in the reserved area. Better 

 maps are now available, permitting closer delineation of primitive area 

 boundaries. Also, during the resurvey all land, regardless of ownership, 

 lying within the primitive area boundaries was called reserved; the ini- 

 tial survey excluded all private lands so situated. 



Sawtimber growth and drain for all species combined on areas presently 

 defined as commercial forest land have been more or less in balance, with 

 the result that the total sawtimber volume in 1952 is about the same as 

 in the middle 1930' s. However, because of the disproportionately high 

 cut of white and ponderosa pines, it is reasonable to assume that the vol- 

 ume of these pines has diminished.
