Cull development under all-aged management of hardwood stands
1963
Trimble, George R.
S2Since the advent of the Civilian Conservation Corps in 1933, and especially since World War II, large areas of the eastern hardwood forests have been put under some degree of management. In most stands culls are a real problem. One of the first steps in a management program is to eliminate these worthless trees. Some stands are so cluttered with culls that complete removal of the overstory and regeneration of a new stand may be the best course of action. However, these are extreme cases: usually the treatment can be less drastic, so that a manageable stand is left after cull removal. But after the culls have been removed, and a management program has begun, new cull trees will in time develop. The question is: how much of a job will it be to keep such stands free of culls? A good indication of the size of this job is provided by records for a number of areas on the Fernow Experimental Forest near Parsons, West Virginia, where the development of cull has been studied in the course of experimental selection management practices used by the Northeastern Forest Experiment Station of the U.S. Forest Service.S3.
