Poles and Piles 



Survey findings indicate that about 1 out of every 6 pine 

 trees 7 to 19 inches d.b.h., or 29 million in all, meets the 

 requirements for poles (based on specifications of the 

 American Standards Association) or for piles. Although 

 the proportion of such trees is slightly greater in the north 

 unit than in either ot the south units, availability of pole 

 material is greater in the southern stands, few of which 

 contain sufficient volume to be logged for lumber. 



It is of interest to the wood-preserving industry that 

 nearly two-thirds of the trees suitable for poles or piles 

 are less than 11 inches d.b.h. outside bark and most of 

 these will furnish poles no longer than 25 feet (fig. 20, see 

 also table 21, Appendix). 



Naval Stores Resources 



In the south pine units there were in 19.15 about 55 

 million round longleaf and slash pine trees 1.0 inch d.b.h. 

 or larger — of which, however, less than 10 million were as 

 large as 9.0 inches d.b.h. (table 8). The second-growth 

 longleaf pines large enough for turpentining usually occur 

 as scattered trees or small groups (fig. 19). Moreover 

 there is a strong demand for such material for posts, poles, 

 piles, and lumber. These facts make it seem improbable 

 that the gum naval stores resource will regain its past 

 importance in Louisiana. 



In 1935 there were in the two south pine units about 

 7)2 million tons of longleaf pine stumps removable by 

 blasting and available for naval stores production under

 These stumps occurred in all forest conditions, but 58 

 percent were on clear-cut areas that contained 14 or more 

 stumps per acre.
