In the Riding Mountain Experimental Forest Area of south-west Manitoba, stands of 100-year-old mixed white spruce and aspen were partially cut in 1953-55 and scarified, leaving treatments that retained from 14 to 100 percent of total stand basal area. This report describes the composition of the stands, based on measurements of 88 permanent sample plots before and after cutting and in 1992. Stand development is described in terms of mortality and growth of the residual stands (including advance growth), hardwood reproduction and softwood regeneration on undisturbed seedbeds, and softwood regeneration on scarified strips within the plots. Options for renewing mature mixedwood stands are also discussed.
