CONSTRUCTION OF A TAPER TABLE FOR JACK PINE IN SASKATCHEWAN (Pinus Banksiana—Lamb.)

A taper table has been developed for jack pine of average form in Saskatchewan. The table is strongly weighted for diameters up to 12 inches and heights up to 70 feet. Beyond these limits the reliability of the table is limited because of the lack of data.The average taper of jack pine in Saskatchewan has proven to be quite similar to that of the Lake States. Therefore, much of the volume table work done in the Lake States should be applicable in Saskatchewan.From the taper table developed for Saskatchewan, volume tables may be constructed on the basis of any desired standard: board foot or cubic foot; any specified top diameter limit; total height or merchantable height. Also, it is possible to determine how many bolts of different diameters, poles or ties can be utilized from each height-diameter class. The table represents average conditions where the average form class of the stand is approximately 65. No allowances for defect have been made.
