For some years, demand for white birch has been increasing in eastern Canada. However, some contractors have noticed that harvesting this species requires greater effort than that required to harvest softwoods or poplar. This report presents productivity data for seven types of forestry machines used in eastern Canada to harvest this species. The data permits a comparison of equipment productivity during the harvesting of the white birch, poplar, and softwood species present in the operations that we studied. We have also estimated the harvesting costs as a function of the species and type of equipment, the observed productivities, and the site characteristics.
