Assuming the same converting factor as previously, the 450 cubic feet given above becomes an even five cords of pulpwood on the average acre, before deduction is made for decay. Because of the deformed and diseased condition of the young growth on the areas burned three times, as described on page 186 a much larger percentage of it will die, or at least will not make commercial pulpwood, than on the areas burned once and twice; consequently, 50 per cent is deducted on this account, making the estimated yield per acre 2.5 cords. The areas burned three times aggregate 6,970 acres, so the total estimated yield of pulpwood becomes 17,425 cords.
On the areas burned many times, the expected yield of poplar will be as follows:
