several hundred acres yield from 12,000 to 20,000 board feet per 

 acre. 



Hundreds of square miles of the better shortleaf forests mixed 

 with oak and hickory over central and western Arkansas and adjacent 

 parts of Oklahoma and Louisiana will cut an average of about 5,000 

 board feet of shortleaf. The character of the forests in the more 

 mountainous parts of Arkansas, where shortleaf is confined chiefly 

 to the flats and warm south slopes, is seen in Table 2, showing the 

 composition of the forest cover in the Arkansas and Ozark National 

 Forests. In the higher hilly region of the Arkansas National Forest, 

 cutting to an approximate diameter limit of 14 inches breast high, 

 or about 15 inches on a 1-foot stump, the pine in the mixed type 

 commonly yields about 2,000 board feet 1 of merchantable timber 

 per acre, leaving about 1,000 feet for seed trees and second cut. 



The average run in private cutting, down to a 12-inch stump 

 diameter limit, is 10 logs per thousand board feet. In a representative 

 sale on the Arkansas National Forest, cutting to a 14-inch diameter 

 limit at breast height, the logs averaged 135 feet each, or 8 logs per 

 thousand'. The bulk of the timber cut ranged from 60 to 180 years 

 old. The oldest good-sized groups or small stands observed over a 

 wide district in central Arkansas were 170 to 180 years, and a large 

 number of them were found throughout the whole region. The 

 yields of these groups or small-sized stands ranged mostly between 

 25,000 and 35,000 board feet per acre, and the maximum acre meas- 

 ured was 62,000 board feet. In Montgomery County, Ark., a com- 

 pany recently cut 2,500 feet per acre (Doyle log scale), or an actual 

 mill cut of nearly 4,000 feet of lumber per acre, from a private tract 

 of 4,000 acres in the high hilly country within the Arkansas National 

 Forest. The best cut of this company was 910,560 (Doyle scale) on 

 160 acres, or an actual mill cut of somewhat better than 1,500,000 

 feet, an average of approximately 9,500 feet per acre.
