practiced to a larger degree in the mixed-type 

 groups, and a relatively insignificant clear-cut area 

 has resulted. The cypress type, which is usually 

 clear-cut, generally restocks to hardwoods or slash 

 pine soon after logging and thereby loses its earlier 

 characteristics. 



Stocking of Forest Stands 



Although well-stocked second-growth stands occur 

 on large tracts, principally in the north-central and 

 northeastern portions, of the survey unit, the forests 

 are generally open and poorly stocked. An analysis 

 of the second-growth longleaf pine stands indicates 

 that more than 60 percent are seriously under- 

 stocked. Longleaf, however, often occurs in open-

grown stands; and the other types show a better de- 

 gree of stocking. 



The predominance of young second-growth 

 stands is reflected in the number of small trees of all 

 species. Trees that have been turpentined com- 

 prise approximately one-fourth of the 8-inch long- 

 leaf and slash pines, one-half of the 10-inch, and 

 two-thirds of the larger sizes. Hardwoods are next 

 to the longleaf and slash pines in point of numbers, 

 followed by cypress and the nonturpentine pines 

 (fig- 4). 



The data of the Forest Survey show that, in the 

 second-growth uncut stands of the pure longleaf 

 type, both the under-sawlog-size and the sawlog- 

 size stands support per acre on the average 123 

 good trees 1-inch and larger of all species. In 

 addition, there are 48 cull trees in the under- 

 saw-log-size, and 31 cull trees in the sawlog-size 

 stands, the removal of which would improve the 

 stands. Only 5 longleaf pines in the under-sawlog- 

 size stands are over 9 inches, in contrast to 27 in the 

 sawlog-size stands. The average ages of the domi- 

 nant trees in these stands, based on measurements 

 at breast height, are 27 and 40 years, respectively. 



The second-growth uncut stands of the pure 

 slash pine type are more heavily stocked than the 

 corresponding acres in the longleaf type. The 

 average acre bears 165 and 187 good trees and only 

 13 and 16 cull trees, respectively, in under-sawlog- 

 and sawlog-size stands. Although only 7 slash 

 pines are over 9 inches in the under-sawlog-size 

 stands, 32 have reached that diameter in the saw- 

 log-size stands. The average ages of the dominant 

 trees in the slash pine stands are 29 and 44 years, 

 respectively.
