In stands of normal density a single operator 

 on a feller-buncher can cut and lay 400 to 500 trees 

 per day. while in the most dense stands this may 

 reach 800 stems per day. The usual rate of cutting is 

 0.4 ha per day per feller-buncher and support crew 

 (G. Henderson, pers. comm.). 



Most harvested trees are between 23 and 50 

 cm diameter; few exceed 60 cm dbh. The feller- 

 buncher cannot handle trunks larger than 1 m in 

 diameter. Such rare trees, missed in the harvests of 

 the early 1900's. may be left standing. This process 

 is most efficient in clear-cutting stands larger than 

 four hectares, with densities of at least 5000 txl. ft., 

 but preferably 10,000 bd. ft., per 0.4 ha (G. Hender- 

 son, pers. comm.). 



6.3.2 Re generation after Harvest 



G. Henderson (pers. comm.) stated that the 

 greatest natural reproduction is achieved in North 

 Carolina when cutting is done on frozen earth in mid- 

 winter. The feller-buncher clearcut method can allow 

 for healthy regeneration if slash is cleared sufficiently. 

 In one North Carolina site, an abundant cover of fet- 

 terbush {Lyonia lucida) grew with the cedar initially, 



but cedars overtopped the shrubs by the fourth year 

 By the seventh year an almost solid healthy stand of 

 cedar saplings covered the harvested area (A.D. 

 Laderman and G. Henderson, unpubl. field notes). In 

 other nearby sites where dense slash remained, 

 cedar reproduction was almost nonexistent (J. 

 Moore, J. Taylor, and A.D. Laderman, unpubl. field 

 notes) (Figure 32). Selective cutting of cedar in a 

 mixed stand discourages successful cedar repro- 

 duction (Little 1950). 



6.3.3 Influence of Competing Ve getation and Slash 



Slash left after lumbering severely reduces 

 cedar seedling establishment (Akerman 1923; 

 Korstian and Brush 1931; Little 1950). Cedar see- 

 dlings form dense stands in cleared areas between 

 masses of slash. On logging rollways from which 

 slash was removed. Korstian and Brush (1931 ) found 

 100,000 to 2 million seedlings per 0.4 ha three years 

 after harvest, and more than 30,000 saplings per 0.4 

 ha five years later. Few seeds germinate, and fewer 

 survive under the 0.6 to 1 .2 m of dense slash often left 

 after logging (Korstian and Brush 1931). Hardwood
