description: The vegetation and soils of hardwood ecosystems in the Elk River Tree Farm, near Campbell River, British Columbia, were sampled and analysed, and the ecosystems classified into a hierarchy of vegetation and site units, using the methods of biogeoclimatic ecosystem classification (BEC). Four plant and four site associations were distinguished. Site units were used as a categorical framework for selection of suitable site preparation method, tree species, and planting microsites. A key was developed to assist Fletcher Challenge Canada Ltd. foresters in site identification and regeneration of hardwood forests on a site-specific basis. A pattern of site units in the study area is demonstrated in the form of a 1:5000 map for a selected, 50 ha-segment of a hardwood forest. It is suggested that the hardwood ecosystems have developed and persisted in response to a seasonally fluctuating water table which can be attributed to poor drainage as a function of fine soil texture, flat topography, and winter-high and summer-low precipitation. The soil water table is very high in the winter but absent or very low in the summer. As a result, the rooting zone in the winter is under the influence of poorly oxygenated water. Such a soil moisture regime is not favourable for the growth of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco]. This study makes recommendations for the management of hardwood ecosystems on a site-specific basis.
