Round-Timber Area 



Round-timber areas are those in which practically 

 all the slash and longleaf pines from reproduction to 

 old growth are unworked for naval stores and in 

 sufficient quantities to justify working either now 

 or at some future time. They occupy more than 

 \}i million acres, or 19 percent of the turpentine 

 area, and constitute one of the main reserves of the 

 future gum naval stores industry (table 7). Most 

 of this area is within or adjacent to well-organized 

 naval stores operations; the remainder is in small, 

 isolated, scattered tracts. 



More than a half million acres of the round tur- 



pentine area is in well-developed stands (fig. 17), 

 averaging per acre 24 round trees at least 9 inches 

 d. b. h., 16 trees in the 8-inch diameter class, and 

 more than 70 smaller trees. An additional quarter 

 of a million acres has an average of two 10-inch, 

 fourteen 8-inch, and more than a hundred 2-, 4-, 

 and 6-inch trees per acre, and will be ready for 

 operation within a few years. On the remaining 

 round-timber area, which includes the young 

 sapling and reproduction stands, as well as the 

 intermingled clear-cut and nonturpentine areas, 

 the trees are too small or too scattered to warrant 

 operation under present practices before 15 to 20 

 years.
