3 Includes cypress type. 



The clear-cut condition class is found on cut-over 

 lands that do not contain enough seedlings or sprouts 

 to qualify as reproduction. Only 1.1 percent (123,- 

 600 acres) of the State's forest land was classed as 

 clear-cut and nearly half was in the longleaf pine 

 type, chiefly in the sand-hill region of the northern 

 Coastal Plain, where dense stands of scrub oak have 

 prevented pine reproduction (fig. 23). 



Site Quality 



Like cultivated soils, forest soils have varying de- 

 grees of fertility and productivity. Next to soil, 

 climate most influences the productivity of the 

 forest. The combined effects of soil, climate, drain- 

 age conditions, and other factors are reflected in the 

 quality of the site and the rate of forest growth. 

 For example, the short, slow-growing stands are 

 usually found on poor, dry soils, whereas long- 

 bodied, fast-growing stands are on moist but fairly 

 well drained soils. 



Site quality is measured in several ways, most 

 commonly for pine in the height of average domi- 

 nant trees at 50 years of age and for hardwoods by 

 the length of merchantable stems of mature trees. 

 The height of pine stems at 50 years is determined 

 from height-on-age curves, based on measurements 

 of many trees at different ages and sites. 



The areas of pine types have been classified as to 

 site quality on the basis of the ability to produce 

 trees at 50 years, as follows: 

 Loblolly pine: Feet 



Good 75 or more 



Fair 55 to 75 



Poor Under 55 



Other pines: 



Good 65 or more 



Fair 55 



Poor Under 55 



For the hardwoods, sites capable of producing 

 trees making at least 3 merchantable 16-foot logs at
