1960). Although the total 

 area of hardwood planta- 

 tions is still limited, in 1979 

 some 16 companies were 

 reported as having hard- 

 wood planting programs, 

 mainly for cottonwoods 

 (Prewitt 1982). Studies 

 have also revealed poten- 

 tials for growing eucalypts 

 in Florida for use in pulp 

 and paper and possibly 

 other products (Geary and 

 others 1983). 



Extensive cooperation 

 between researchers and 

 industrial and other groups 

 concerned with the manage- 

 ment of southern hard- 

 woods has been an impor- 

 tant factor in southern 

 forestry research. A south- 

 ern hardwood forestry 

 group, for example, orga- 

 nized in 1951, held regular 

 field meetings to study 

 hardwood management, 

 sponsored classes in log 

 and lumber grading, estab- 

 lished long-term timber 

 growth studies, and assisted 

 in other research programs. 

 A hardwood research coop- 

 erative in North Carolina 

 involved industry and univer- 

 sity participants in a series 

 of growth and yield studies. 



In the area of forest mensu- 

 ration and biometrics, 

 recruitment of Roy Chap- 

 man in the early 1930's 

 added the first in a series 

 of specialists who have 

 contributed statistical ex- 

 pertise to a wide variety of 

 research investigations. In 

 later years other scientists, 

 including J.G. Osborne, 

 C.A. Bickford, T.C. Evans, 

 Frank Freese, and H.T. 

 Schreuder, provided similar 

 assistance to improve 

 sampling design and other 

 statistical techniques in 

 many research projects. 

 LR. Grosenbaugh led in 

 the development of proce- 

 dures for variable radius 

 plot sampling and other 

 techniques that helped 

 increase efficiency in timber 

 inventories and manage- 

 ment planning (Grosen- 

 baugh 1958). Cooperative 

 efforts with F.X. Schumach- 

 er, of Duke University, 

 included publication of an 

 early text on sampling 

 methods in forestry and 

 range management (Schu- 

 macher and Chapman 

 1942). Scientists at the 

 University of Alabama 

 provided an understanding 

 of relationships such as 

 that between point density 

 measurements and subse-
