Many yield tables represent a normal forest. Early yield tables assumed ‘normal’ or near max’ stocking and hence were called “normal yield tables’. These tables are of limited usefulness because most stands do not have normal stocking but rather something less.

• Temporary plots are deliberately located in fully stocked or normal density portions of a series of stands of varying ages representing various site qualities
• Volume-Age curve for each site quality classes & ages to compile normal yield tables

Application

• Limited application, no reliable methods are available for predicting yields of non-normal or under-stocked stands
• The usual procedure has been continued to compute the ratio of BA of stands to Bashown in Normal yield table and to apply this ratio for volume as well
