Expanding Options for Reforestation of the Cumberland Plateau

Stems of d.b.h. 4 inches or greater in a low quality stand in Tennessee dominated by white and scarlet oak (Quercus coccinea) were sheared in September-November 1976, chipped, and removed. Sawtimber quality trees (30) in the 37-acre area were felled separately by conventional methods. Residual trees (2-3 inches d.b.h., ht. over 4.5 ft) in some areas were injected with herbicide. One-acre plots were planted with 1+0 loblolly pine, 2+0 white pine (Pinus strobus), or 1+0 yellow poplar, or left to regenerate naturally. After 2 years, survival of all trees was good (83% or over) and average height of loblolly pine, yellow poplar and desirable natural stems (white, scarlet or black oak, Quercus velutina) was 3.3 ft, significantly different from that of white pine (1.5 ft). It is concluded that poor quality stands can be cheaply improved by this method, although release from competing vegetation may be necessary, especially in the case of white pine.
