Silvicultural Implications in Shrub Biomass Utilization

In many regions of the United States, forest stands contain high levels of competing native and non-native shrubs that pose a significant challenge to regeneration efforts (Royo and Carson, 2005). Typically, site preparation techniques based on either mechanical or chemical methods are employed to reduce the presence of woody competition and to increase the favorability of a site for planting or natural regeneration. Historically, these treatments have been at a cost to the landowner; however, the development of biobalers and other new and forthcoming biomass harvesting technologies may facilitate the economical removal of this material from a site. It is important to avoid negatively impacting the long-term productivity of the site while harvesting these materials.
