Approach of Abnormally Stocked Forest Stands of Douglas Fir to Normal Condition
Abstract:Permanent sample plots alone can furnish the solution to many questions arising in the correct application of yield tables. Records of from five to twenty years standing in even-aged stands of Douglas fir are here used to show the tentative trends of abnormally stocked stands to a normal condition. Understocked stands become more normal at a rate dependent upon the initial degree of stocking in inverse ratio, and conversely overstocked stands become less overstocked. The ultimate meeting place of the two is taken to be the point of true normality.
