The effect of short duration, heavy grazing by cattle was evaluated 3 and 6 years after burning and seeding of an aspen (Populus tremuloides Michx.) grove. Replicated paddocks of June grazed (early), August grazed (late), and ungrazed treatments were established. Regardless of treatment, density of all woody species was lower 6 years after burning than after 3 years. Early or late season grazing reduced the density of aspen and wild raspberry (Rubus strigosus Michx.). Late season grazing promoted a greater density of unpalatable western snowberry (Symphoricarpos occidentalis Hook.). Grazing reduced the height of aspen, preventing the development of a forest canopy. Herbage production averaged 1,700 kg ha-1, not differing between years 3 and 6: but the proportion of smooth brome (Bromus inermis Leyss.) increased while orchard grass (Dactylis glomerata C.) declined, Burning of aspen forest in Central Alberta followed by forage seeding and short duration, heavy grazing is an effective, economical range improvement tool.
