Because of the projected wood shortages and the push for greater utilization of the forest resource， increasing empha- sis is being placed on pulping bark rather than debarking bolts or segre- gating wood/bark chip mixtures。 Im- portant to determining the usefulness of the approach with a particular species is determining the proportion of lignified cells that exist in the bark and that will survive normal cooking procedures。 Also， it is important to determine what percentage of these cells will contribute in a favorable way to the resulting paper product。
