Bioenergy crops are being developed globally to reduce greenhouse gas emissions, often on marginal lands with minimal inputs. A key concern is the potential introduction of invasive species. This commentary argues that invasion risk can most effectively be prevented through a life-cycle approach that applies scientific and policy tools at each stage—from crop selection to field production, feedstock transport, storage, and decommissioning—avoiding the "kudzu effect." The paper provides a framework to guide regulatory agencies in the selection and permitting of biofuel feedstocks.

In an effort to reduce greenhouse gas emissions, expand domestic energy production, and maintain economic growth, public and private investments are being used to pursue dedicated feedstock crops for biofuel production. This commentary addresses the necessary balance between designing biofuel feedstock crops to require minimal inputs yet preventing them from surviving outside the cultivated environment.
