immense practical value to 

 both private and public 

 landowners. 



One of the major activities 

 in the field of timber man- 

 agement has been the 

 development of growth and 

 yield tables, both for natural 

 stands and managed plan- 

 tations. The initial set of 

 yield tables in Miscellaneous 

 Publication 50 (1929) was 

 supplemented by Schu- 

 macher and Coile's 1 960 

 publication "Growth and 

 Yield of Natural Stands of 

 the Southern Pines" and by 

 a subsequent work describ- 

 ing soil -site relationships 

 and yields of slash and 

 loblolly pines (Coile and 

 Schumacher 1964). The 

 comprehensive information 

 on growth and yields devel- 

 oped by researchers has 

 been summarized in an 

 annotated bibliography 

 (Williston 1975) and in 

 general reviews by Farrar 

 (1979) and Burkhart (1979). 



yields of loblolly pine planta- 

 tions in the lower coastal 

 plain of the Southeast. 



Growth and yield data for 



loblolly and shortleaf pine 

 in the west gulf coastal 

 plain were published by 



Burton (1980), Similar 

 findings have been made 

 available for essentially all 



major forest types and 

 conditions in the South. 



In this research on timber 

 yields, cooperation with 

 forest industry groups and 



universities has been an 

 important factor, as in the 

 case of a plantation man- 

 agement research coopera- 

 tive at the University of 

 Georgia and cooperative 

 slash pine density studies 

 at Cordele, GA. The growth 

 and yield data thus devel- 

 oped have proved to be 

 essential for analyses of 

 thinning and other manage- 

 ment alternatives and for 

 evaluation of attainable 

 yields. 



Many scientists have con- 

 tributed to this wealth of 

 knowledge. J.L Clutter and 

 associates at the University 

 of Georgia (1 984), in cooper- 

 ation with Forest Service 

 scientists, developed data 

 on stand structure and 



Research and experience 

 in timber harvesting have 

 led most large landowners 

 in the southern pine region 

 to opt for clearcutting and 

 planting or seeding of pine 

 stands. These practices 

 have proved to be most
