wood characteristic mapping was considered as a means for optimizing the value chain of northwestern ontario tree species. a literature review was completed which investigated the relationship of wood morphology to wood characteristics and end use as related to potential opportunities for northwestern ontario. it was found that there was insufficient study on the area of interest to make any definitive conclusions; save that research is needed. the literature did, however, provide a general understanding on issues being assessed. based on the findings of the literature review, a case study on mapping wood characteristics of eastern larch (larix laricina (du roi) k. koch) grown in the thunder bay district was completed. it was found that the greatest variability displayed by eastern larch wood grown in thunder bay district was between sites and radial position within trees. in all cases of statistical analysis, variance between sites was significant. radial variability was significant for all the selected wood properties tested except for moe perpendicular to the grain. longitudinal or axial variability was significant in all the selected wood properties tested except for wood density.
