This fact sheet describes research conducted at Utah State University that identified factors to improve the success of regenerating aspen in southern Utah. Evaluating past silvicultural regeneration treatments indicated that the presence of pre-harvest advance reproduction, site preparation by broadcast burning, and decreasing browsing pressure could increase the quantity of aspen regeneration. The outcomes are generalized into an easy-to-use model, the Aspen Pyramid, to facilitate decision-making regarding regenerating aspen.
