Pre-Scarification and Strip Clearcutting to Obtain Lodgepole Pine Regeneration

H. J. Johnson

Open full text 1 citations

Abstract

In 1952 an experiment was conducted near Strachan in the lower foothills of Alberta in a study of regeneration of lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) obtained by pre-scarification and strip clearcutting. The results to 1968 support this technique, regeneration on pre-scarified areas having exceeded 80 per cent stocking. Height growth of the tallest seedlings on scarified areas was over 50 per cent greater than those on undisturbed areas.
