Good biofuel crops can make great invasive species. That’s one of the findings of a new report released today by the National Wildlife Federation. Growing Risk: Addressing the Invasive Potential of Bioenergy Feedstocks explores the challenges and policy solutions surrounding the use of non-native and potentially invasive bioenergy crops. Numerous non-native and genetically modified species are already being considered for use as biomass feedstocks. Growing these plants may appear to be a great source of homegrown renewable energy, but without proper precaution, producers run the risk of unleashing the next big invasive species catastrophe that could devastate native ecosystems, deplete scarce water resources and require significant resources to control.
