A study of the response of vegetation and planted Engelmann spruce seedlings to operational site preparation procedures for reforestation was initiated in 1986 in the Grenogle Creek Watershed of southeast British Columbia. The five site preparation techniques tested consisted of (1) brush blade with contour, (2) brush blade across contour, (3) FMC blade with contour on gentle to moderately steep terrain; (4) FMC dip and dive on steep slopes; and (5) prescribed burning on moderately steep slopes. Untreated plots were located in the undisturbed areas between scarified strips. Scarification was conducted in brush land rated not satisfactorily restocked (NSR). Slashburning was performed following more recent logging, but would be similar to a brown and burn treatment of NSR land. The study was conducted on a northeast-facing slope in the ESSFwm biogeoclimatic subzone. This report presents data on vegetation development and Engelmann spruce growth during the first 5 years following planting.
