DescriptionFour mature but grossly under-stocked (15 to 23 percent of normal) aspen stands were regenerated by suckering following shearing. Eight years later, aspen standing crop varied with site quality from 3.4 to 8.0 tons per acre -- nearly the potential for these sites at this age. Shearing is as effective as complete clearcutting for regenerating aspen.
