reserved, the annual yields would be gradually 

 increased, as shown below: 



Year: Calculated yield 



1935 726 million board feet and 752,000 cords 



1940 740 million board feet and 859,000 cords 



1945 753 million board feet and 982,000 cords 



In addition to the above yields from good trees, 

 the saw-timber trees removed each year have at 

 least 164,000 cords of upper-stem wood; and the 

 annual yield from cull trees, assuming 20 years to 

 remove the present accumulation of cull volume, 

 would approximate 9,000 cords. This material is 

 at least suitable for fuel wood, and a small part of 

 it may be used for pulpwood. Taking into account 

 some of the practical limitations, it seems reasonable 

 to believe that about three-fourths of a million 

 cords of pine pulpwood could be removed annually 

 from the stand without endangering the future 

 timber supply of the present industries. 



In the pulping hardwoods, the increment of live 

 sound trees 6 to 12 inches d. b. h. will provide an 

 annual pulpwood cut of 177,000 cords, with 

 sufficient growing stock left to maintain and even 

 increase the stand of trees 14 inches and larger. 

 In addition, trees removed for saw timber each 

 year have about 90,000 cords of top wood. The 

 sound volume removable in cull trees is 150,000 

 cords per year, assuming that the present accumu- 

 lated volume is harvested over a period of 20 years. 

 Hence, an annual cut of at least 200,000 cords of 

 material suitable for pulpwood seems possible. 



These pulpwood estimates presuppose that the 

 cut is well distributed over the unit and that 

 diversified utilization occurs. At present, mills of 

 all kinds and sizes are well scattered throughout the 

 unit and are operating in all kinds of stands. There 

 are no areas in which the timber is inaccessible. 

 Since the land is controlled by a variety of owners 

 with various plans of management, some stands 

 are available for logging at all times. As stated 

 earlier, 86 percent of the annual board-foot incre- 

 ment is taking place on economically accessible 

 sawlog-size stands; but the volume on the remaining 

 timber areas is rapidly increasing also. 



Poles and Piles 



Included in the total volumes previously dis- 

 cussed are 35 million pine trees suitable for poles or 

 piles. Ail of these will satisfy the requirements for 



southern pine poles as set up by the American 

 Standards Association. About 20 percent of the 

 pine trees 7 to 19 inches d. b. h. were considered as 

 pole material by the cruisers of the survey, who 

 found the heaviest concentration of poles and piles 

 in the territory shown in figure 14.

 PILES ARE MOST ABUNDANT 



Figure 14. — Location of the main body of the pole and pile 

 timber, as indicated by shading 



Table 21 shows the total number of pine poles 

 and piles classified according to diameter and 

 length. Owing to the recognized difficulty of 

 classifying standing trees for poles and piles, this 

 table may not give the exact number to be found 

 within the unit, but it does show the probable 

 percentage of the total number of each size class. 

 Of the trees suited for poles and piles, 84 percent 

 are under 13 inches d. b. h. outside bark; the 

 remainder are 13 to 19 inches in diameter. Sig- 

 nificant is the fact that 70 percent of the total poles 

 and piles are 25 feet or less in length. The com- 

 monly used 35-foot length forms only 7 percent of 

 the available supply, while only 1 percent of the 

 present supply of poles and piles are at least 50 feet 

 long. With only 14 percent of the total supply 

 over 30 feet long, pole operators in this unit need to 

 develop a greater market for the shorter and smaller 

 pieces.
