Abstract

Abstract: Short‐rotation coppice systems like shrub willow are projected to be an important source of biomass in the United States for the production of bioenergy, biofuels, and renewable bio‐based products, with the potential for auxiliary environmental benefits and multifunctional systems. Almost three decades of research has focused on the development of shrub willow crops for biomass and ecosystem services. The current expansion of willow in New York State (about 500 ha) for the production of renewable power and heat has been possible because of incentive programs offered by the federal government, commitments by end users, the development of reliable harvesting systems, and extension services offered to growers. Improvements in the economics of the system are expected as willow production expands further, which should help lower establishment costs, enhance crop management options and increase efficiencies in harvesting and logistics. Deploying willow in multifunctional value‐added systems provides opportunities for both potential producers and end users to learn about the system and the quality of the biomass feedstock, which in turn will help overcome barriers to expansion. Abstract : Willow biomass crops have been studied in the United States since the mid 1980s, but only recently has this research resulted in the deployment of this system across the landscape. This initial deployment occurred because of support of the U.S. Department of Agriculture's Biomass Crop Assistance Program (BCAP) and a regional company's (ReEnergy) decision to sign long‐term contracts to purchase biomass from willow growers. Shrub willow has the potential to be effective in multifunctional systems and examples of these systems are being deployed in the United States despite the lack of direct value being attributed to these systems.
