The production of regional biomass yield tables for Canada is feasible. This conclusion is based on the knowledge that the data bases used to construct the provincial yield tables exist and can be converted to regional biomass yield tables, by the application of appropriate tree biomass equations. There also exists a set of factors produced by the ENFOR program for the conversion of gross merchantable tree volume to weight. Factors were also developed for other tree components - bark, top, branches, foliage and stump. Further factors to predict the stand volume and hence biomass for trees below the minimum size measured in permanent sample plots are available. The resulting biomass yield tables would then account for all Canadian forest biomass excluding only the biomass of roots and non woody vegetation. This study identifies the necessary data and its sources and provides a working plan for the production of the yield tables. It includes a pilot study, provides a 6-yea schedule, and makes a global cost estimate of $1 120 000.
