註釋Within the Sub-Boreal Spruce Zone (SBS) of the Prince Rupert Forest region, the forest manager encounters a considerable range of stand types, forest productivities, and stand responses to various kinds of treatment. Such variability arises not only from different stand histories but also from intrinsic differences in the climate, topography, geology, and soils of various forests sites or ecosystems. This Field guide aims to provide a practical, efficient tool to identify decent intrinsically different ecosystem units in the field.
